An extensive guide on how to repair a ship launching marine air bag

1. Clean the surface of air bags

First and foremost, you must clean up the air bag’s surface to make sure there is no sand or oil on it.

Then dry it and put it at a clean workplace. It could be in a shaded area or outdoors but please make sure it’s not going to rain/snow anytime soon!

Ensure that the marine air bag is fully dry before beginning the repair process.


2. Check and mark the damage area

Mark the area that needs to be repaired, which must be expand from center to outside (20-26cm) and remember that do not ignore the hidden damaged areas.

Note: the expansive range depends on the size of damage areas.


3. Repair

1) Sand the surface of damaged area until the cords show.


IMPORTANT: DO NOT damage the cords. Just exposing the cords is enough! 


2) For some long cracks, you need to use needle and cord layer to suture

Sewing needle position about 2 ~ 3 cm away from crack, about 10 cm distance between stitches.


3) Wash the surface of repair part with gasoline and dry it.


4) Brush up some special glue on repair part

The glue is made by mixing raw rubber material with gasoline together.


How to make the ‘special glue’: Mix rubber raw material and gasoline together at a ratio of 1:8, meaning 1 portion of rubber requires 8 portions of gasoline.


5) Prepare the repair rubber material.

The repair material should be same with the airbags’ outer layer material.

Meanwhile, the structure layer 2-6 will be based on the size of damage area.

Seal the leakage area using pure rubber belt of 1mm thickness, the belt width and length should be more than 1cm around the crack.


6) Put the layers on the damaged areas.

The first layer of interleave is ordinate, the second layer of interleave is bias.

The angle should be same with the airbag, and it should be 20mm bigger than the first layer.

The third layer also is bias, the angle should be contrary with the second layer. It also needs 20mm bigger than the second layer.

From 4-layer to 6-layer, keep repeating the steps above. Circular angle should be required by interleave and the semi-diameter should be 40-50mm.



4. Thermal Vulcanisation Process

Next, you will have to vulcanise the repaired area.

At the process of vulcanisation, please remember to control the temperature up to 150 ±5 °C and apply maximum pressure to that area using a jack. Then closed the heat steel plate and permit it to cool very slowly to 60°C ( about 40 minutes). During this time, DO NOT remove the jack.



5. Inspection (before using air bag)

Check the repair area to make sure that are no holes/leakages.

Inflate the repaired marine air bag and monitor if there are no major leakage of air throughout the test duration.

NOTE: Please ensure the patched air bag is fully cooled down to room temperature BEFORE inflation for tests.

MAX air bags and dredging hoses recognised by world renowned association

We are extremely proud to announce that recently in 2018, MAX group’s products have been thoroughly inspected, audited and recognised by the Product Quality Congress Association.

MAX products tested are the ISO14409 rubber airbag product category; and dredging-use floating hose category. We take pride in both products as they completely excelled and outperform almost all of the competition. In fact, when we were made aware of the competing products with better performance, their pricing was at least 35% higher than MAX’s.

This is a delightful surprise as our team did not expect such a sudden approach from the committee as we had no prior knowledge of such an experiment going on at the moment.

high pressure rubber airbag (Example of ISO14409 rubber airbag category product)
max rubber products (Example of dredging-use floating hose category product)

What happened?

The procedure involved the committee purchasing 10 similar products from the market and perform various extensive tests respectively to determine & understand more of the industry product.

The inspection is entirely random, done with anonymous purchase from the committee. (MAX has no prior knowledge of it, too). We caught up with the committee and understood that purchasing of goods have been done in January 2018, with the committee purchasing 5 similar products from various manufacturers (one of them being MAX Groups Marine) and carry out a fully documented testing covering a wide range of tests.

Our marine airbag has managed to perform in these areas:

  • Ranked in No.1 for fatigue testing results (best results after tested with 100 cyclic fatigue loading conditions)

  • No.1 in burst pressure/rated pressure ratio

  • Tied at No.2 for product response to sharp object.

  • Ranked in No.2 in total tensile strength of material used.

It is important to note that these tests are performed on our usually manufactured products, and tested without MAX’s knowledge. So, this is a further testament to our general product quality manufactured from our day-to-day operations. Learn more how our product is superior to others in the market by reading this “5 Things Other Airbag Manufacturers Do Not Want You to Know” article.

Dredging hose test details are undisclosed at the time of this writing but we were made aware that the results generally perform in top 4 in all tested categories.

After the tests

After the test results were available, MAX was then approached by the committee to undergo further factory inspection procedure in order to better understand the industry. As one of the most trusted brand in marine equipment manufacturer and supplier in the industry, we were more than happy to help!

In this trip, the personnel further inspect our raw materials, production procedures, and test some more of our available products. We were delighted to help provide further advice and explain on our superior production processes.



We were briefed that such random checks were to restore global public confidence in China-manufactured products and to solidify China as a global manufacturing powerhouse. Manufacturers that export out products that failed testing is also further investigated by the relevant authorities.

“The problem with many of these industry products is that the usage of them is highly correlated to the safety of users. So we would like to make sure, as we can, that the manufacturing community takes their promises seriously. Marine equipment is only one of the many sectors we cover from heavy engineering, construction, chemical products. We are pleased to see MAX Group uphold such high product quality standards, which definitely boosts market confidence in this product category.” – Dr. Chen Y.B., senior committee of congress.

5 Things (Other) Marine Airbag Manufacturers Do Not Want You to Know

High quality marine rubber airbags are commonly used for projects in the heavy industry and marine shipbuilding sector.

high pressure rubber airbag

Some of their most common uses are as follows:

  • Launching of 250-ton to 10,000-ton ships or boats. Sometimes even more
  • Launching of heavy large structures up to 10,000-tons
  • Hauling out of large marine structures including ships for repairs or recycle
  • Providing additional buoyancy for marine salvage projects or flotation needs (i.e. reducing draft of barges etc)
  • Mobilisation of heavy structures on land (a suitable alternative to transporters)
(Below: MAX Marine Airbag used for ship launching)

спуск катера на воду

The usage of marine airbags are especially common in Asia, particularly in the shipbuilding space. However, there has been a misconception in the product, as well as large differences in pricing available in the market. In fact, many of the suppliers claim they are providing xx amount of layers, xx amount of weight etc to justify that their product quality is the same as many of the trusted manufacturers’ products. The vast differences in prices manage to confuse many of these airbag buyers. So, what are the “promises” usually made that a buyer should be careful of?

If you don’t know of marine airbags, and would like to learn more about it, here’s our product page.

Interested to learn how our on-site team can help with mobilisation, launching and hauling? Visit our service page.


1. Weight

It is not uncommon to hear certain suppliers claim something along the lines of “Our rubber airbag of this size weighs xx kg, it proves that our materials are of good quality and we give you more bang for your buck!” or when the weight info is more than a competitor, they claim that their airbags “have more materials in it so it is better!”. However, one should really understand what’s in an airbag, and how weight is affected. And by understanding more, you will see why this is a huge misconception.

Ship-launching airbags are made from rubber and strengthened by cords to provide sufficient bearing capacity. In the act of confusing buyers, some manufacturers actually have more unwanted foreign materials in the rubber sheets, which actually makes them heavier. Rubber is relatively less dense. The availability of more foreign substances in rubber will make them much heavier, but at what cost? It will substantially decrease the elasticity (which means it will fail much sooner after a couple of uses). Some even speed up aging of the rubber and massively decrease its usage safety.

Not all of them do this on purpose, though. Some have these added unneeded foreign materials in the rubber sheets due to dirty working environment or poor quality control procedures. Yet, an overly-aggressive salesperson sometimes mislead and even turn this “higher weight” info into a ‘good’ point to convince buyers. That is why in our facility, we ensure a clean working environment and set-up strict procedures to curb this issue. Only those materials intended to go into a quality marine airbag, goes into them.

Fact #1: Weight is not a good indicator of quality.

rubber airbag quality

2. Raw Materials

Ideally, airbags should be made of new rubber material that adheres to the following standards:

  • ISO34-1  Tear Strength ≥400 N/cm
  • ISO37  Tensile Strength ≥18 MPa, Elongation at Break ≥400%
  • ISO1761-1  Hardness (Shore A) 60±10°
  • ISO815-1  Compression Set
  • ISO188 Requirements After Thermal Aging
  • ISO1431-1 After Static Ozone Ageing

The keyword here is new. MAX NEVER uses recycled or reclaimed rubber material in airbag production. This is a huge red flag. Quality rubber makes the foundation of the whole “inflatable roller” idea, especially when it has to bear very high values of weight on top. Recycled and reclaimed rubber have substantially lower elasticity and has a very fast ageing rate which compromises the integrity of airbags. Use these recycled rubber airbags a couple of times and you will realise they burst very easily.

On the other hand, cords play a big role, too. These “tire cords” are supposed to be three-strand cords with more than 205 N strength per cord. Some manufacturers, like MAX, procure and use a higher strength cord (above required standard) to ensure quality strength; but some other suppliers use two-strand cords with lower strength sometimes. There is also the difference with other cords like dacron cords etc. The difference in use of raw materials can have a cost difference of more than 65%!!

Fact #2: Raw materials in airbags are sometimes very different from one another, and hard to detect.

manufacturing air bags

3. Fabrication Technology

Given all the materials are constant, do you think the end product will be the same? That is not actually the case. Even if both makers are using the same type of materials, the technology and expertise in production would set them apart. It is important for a manufacturer to suitably use certain types of automation and machines to standardise certain procedures, ensuring a very consistent output which minimises mistakes and errors. Skilful workers (and NOT general workers) are needed. With much experience, these personnel are the ones who will make sure every step is according to standard and will result in a consistent, high quality airbag. Details like the alignment, tightness and strength of parts should be inspected closely.

At MAX, we practise a new innovative fabrication technology. This practice enables us to fabricate rubber marine airbags in a more consistent manner, enhancing strength by having multi-directional overlapping layers and minimise human errors.

In addition, we have highly qualified vulcanisation experts. When it comes to manufacturing these high pressure airbags, vulcanisation is a key process where over-vulcanisation or under-vulcanisation can bring very large performance differences!

Fact #3: Even with the same materials, it is impossible to expect two different manufacturers to have exact product result, because of different fabrication technology and manufacturing processes. Some are better than the others.


4. Layer Quantity Overstatement

Imagine the shock when we encountered some customers came to us asking for a 15-layer airbag!

Most ships/structures can be handled with our 7-layer type airbags, or in some cases (sharp hull or challenging work conditions) maybe up 10 layers. But anything more than 10 is definitely not necessary. These overstatements cause industry-wide confusion, and buyers thought they are getting more with these cheap prices. However, we are convinced our MAX 7-layer type airbags would perform better than many of those “15-layer” airbags. Truly reputable suppliers will understand that these high layer counts mean nothing. For those “15-layer” claims, how many layers do you think you are getting?

Also, quantity is not everything. It is vital for the buyers to educate themselves of the difference in quality. And the best part is to try our products to see the difference for themselves!

Fact #4: Find a trusted manufacturer who does not over-promise and under-deliver.

5. Third Party Inspection

Third party inspection is great. Our company happily offers third party inspection certificates from various inspection parties upon customer’s request. However, it is important to understand that inspections are not a guarantee of product quality. They are only able to make sure they are made according to standard guidelines. It does not ensure the product quality is on par with another similarly inspected product. Because these inspections are made with overall product outer inspections.

As we have mentioned earlier, it is a combination of the finest raw materials and skilful fabrication expertise that makes a product great. The fabrication skill can’t be “inspected” and compared on a newly made product. Besides, some manufacturers like MAX even go above and beyond the guidelines to use much higher grade materials in our products.

A more specific example would be product lifespan: product A and product B might work the same for the first two uses, but gradually, you will realise product A degrades, loses its flexibility and strength faster; while product B maintains its performance, and has a much longer useful life. In the long term, you would save more by using product B, even if sometimes it cost a little more upfront.

Fact #5: Third party inspection is not able to 100% ensure integrity of airbag. Find a trusted source.

Try them out

So, these are some of the common misconceptions of marine airbag buyers. Some of these points actually apply to our other products like pneumatic fenders, dredging hoses, foam fenders, rubber fenders, winches etc too. If you are currently using other brand’s products, try contacting us to get a quote. We are confident that if you tried our rubber airbags, you will realise the difference upon usage!


Ship Repair, Launching & Marine Salvage using MAX Airbags

The Ultimate Guide to Ship Launch, Ship Repair & Marine Salvage using MAX Air Bags

MAX Marine Airbag technology is an extremely flexible technology where it can handle heavy structure launchings (ships, boats, floating jetties, caissons), ship repair haul-ins and marine salvaging cases.

While we cannot disclose the details of calculation due to professional competitive advantage, this guide aims to give an overall view of how MAX advises our clients.

Ship launching using such marine rubber inflatables is superior to many other conventional methods.

Airbag ship repair and launching offer shipyards a cheaper, safer and eco-friendlier option than traditional methods. Tweet this!

Ship Launch Section

MAX Rubber Airbags are really cost-effective in launching a vessel.

They are very suitable even for smaller-sized barges to tug boats up to bigger-sized chemical tankers and containerships.

However, it is very important to understand that rubber airbag launching is not a ‘one-size-fits-all’ method.

Marine rubber air bag launching is not a ‘one-size-fits-call’ method. Tweet this!

In fact, MAX team would need to understand all the necessary technical specifications of the vessel (or structure, as this launching method can also be used to launch caissons & floating jetties etc) and many external factors.

The first step is to identify the vessel size & dimensions.


Identify Main Dimensions & Types of Vessel

At MAX, we believe in listening before we jump to conclusions and putting our clients priorities first.

Before proceeding in advising, MAX staff would normally request our prospects to fill in a technical specifications form.

Factors like:

  • Length overall (L.O.A.),
  • Beam,
  • Draft,
  • Launching weight (light weight) of the vessel
  • Working height (distance between ground and the hull of the vessel), are just a few crucial things we need to know.

This enables our team to understand the weight dynamics of the structure during launching.

Equally as important, we also ask for a GA plan as the main ship design different designs of the structure plays a role in choosing an efficient air bag solution.


Selection of MAX Marine Airbag

After understanding the type of vessel and its principal dimensions, MAX staff is then able to recommend the:

  • Types
  • Sizes
  • Numbers of airbags.

A weight allowance of a certain percentage of the vessel weight is taken into consideration.

This helps MAX to ensure a safe launching process by not overexerting the rubber airbags and also have a safety margin, should there be any additional weight carried by the vessel during launching.

It is important to take into consideration a safety factor of weight allowance during selection of marine air bags. Tweet this!

Based on the dimensions and structural design, the team can recommend the dimensions of the airbag in terms of length, diameter and type.

Then, based on calculations and careful projections, MAX staff is able to determine the guaranteed bearing capacity per airbag.

At this point, extra airbags for launchway mobilisation will be included in our recommendations.

The selection process of MAX airbags is also checked by our MAX Smart Ship launching software.

launching calculator

Due to professional competitive advantage, this is a screenshot of just a part of the software.

This software is developed by MAX software engineering team and acs as a double-checking process to enable a safe recommendation of the optimum number and types of airbags for use.


General Ground Structure Preparation

MAX airbag launching process requires a hard ground so that the whole structure will not sink during launching.

If the ground consists of sand or is soft, there are many options that our staff will recommend.

Sandbags are a very commonly used solution.

MAX also helped many of our clients prepare concrete ground as launching slipway for airbag use.

This would require a very delicate study of the nature of the ground and in-depth analysis on a case-to-case basis. Thus, it is crucial that this aspect should not be overlooked.

For MAX, we have helped our clients solve these issues in many years of our experience in ship launching.

Contact us if you have such tricky issues with the launching slipway and need professional assistance.

Power and miscellaneous issues:

Other pre-launch conditions like power generation issues including the design & supply of diesel generator systems will also be discussed with our client.


Selection of Slipway Winch

We do not recommend other general-usage winches. Our slipway winch is designed specifically for this use – launch or haul-out ships.

  • Winch speed within the industry standard of ship launching with airbags
  • Emergency reverse-braking mechanism
  • Various built-in safety mechanisms for common issues when handling ships.
  • Control panel tailored to conditions in shipyards / marine-use
  • And more.

Safety should be the No.1 consideration here. Our winch is built for the job.

Determining winch capacity:

The force needed to support the vessel will be determined by taking into account the slope angle.

The engineering team will have to calculate and find out the type & strength of slipway winch required to hold the structure in place.

Determining electric or hydraulic powered?

The decision of whether to use an electric or hydraulic winch is also very important.

A hydraulic winch may be more expensive but might be more durable and more suitable in certain cases. Though it depends on the user and conditions.

Pulley blocks, shackles, suitable wire rope types and necessary equipments will also be recommended if needed.

Pulling force plays an especially huge role for certain launching projects that require a slow and steady launch approach, needing the winch to be able to operate long periods of time.


Placing of Rubber Airbags

MAX team uses 3D projections to determine the placement of rubber airbags at ready-launch position.


This helped give a 3D view on how to evenly distribute the weight of the vessel/structure for maximum safety.

MAX takes into careful consideration the distance between components and how to coordinate the metal strut/stand locations.

3D-printing is used for some of MAX’s vessel launch projects, too.


The Actual Process of Launching the Vessel

First time users usually require MAX consultation crew to be on ground to help clients launch their vessel.

We are able to facilitate the whole preparation together with supervision of the launching process at a small consultation fee for our clients.

Equipped with decades of experience in launching and careful projections, our team ensures the project success and the safety of the crew.

With its advantages, launching of structures up to 10,000 Tonnes using this method is pretty common these days.

It is widely acknowledged that our quality launching bags are able to be used up to more than 5 years and is very cost efficient compared to most traditional launching methods.

MAX Airbag launching process

This is a simple breakdown of the common air bag launching process.

  1. It started with a winch holding the vessel in place.
  2. Airbags are placed underneath the ship’s hull.
  3. Air bags are then inflated.
  4. The transfer of weight from support blocks to having the airbags actually lifting the vessel itself.
  5. Remove the support blocks.
  6. Then the winch’s pulling force is slowly decreased to enable mobilisation of vessel towards the sea line.
  7. At a certain point, the connection between winch and vessel will be released using MAX quick release shackle.
  8. The vessel, assisted by gravity and launching bags, will be launched safely into the sea with minimal risk.


Please note that however, there are many different scenarios to cater to different situations and different vessels, so this is just an overall idea of it.

Ship Repair Section

Like the ship launching method, the main concept and preparation process are both very similar, just reverse the process. Please go through ship launching section first before reading this section to better grasp the idea.

Most calculations are inverted and the core concept of having strong enough pulling force (in this case, hauling winch) is key to maintaining a steady hauling process for ship repair.

Understanding Principal Dimensions & Weight of Vessel

Similarly to the vessel launching process, the hauling in of vessel for repair projects require MAX to analyse its dimensions in detail.

Weight, overall ship length and width are some of the aspects MAX engineering team would take under consideration.

The design of hull and ship has to be considered as well for hauling process as structural differences can affect the types of airbags used.

Choosing Suitable MAX Airbags

Main dimensions and structural design of the vessel helps MAX team to recommend the dimensions, thickness, specsnumber of air bags needed.

When choosing the most suitable bags for hauling use, safety is our number one priority.

Marine bags should not be overexerted.

That is why MAX’s experienced technicians will add a percentage of weight contingency in calculations.

This will add a ‘safety cushion‘ also to accommodate any excess weight that the vessel may have added.

Next, detailed projections and careful calculations enable MAX to identify the bearing capacity per airbag.

This figure is subsequently used to deduce the total number of bags needed, including extra bags for launchway mobilisation.

MAX team will then use our in-house developed MAX Smart Ship Launching software to double-check the calculations.

Pulling Winch / Hauling Winch with Enough Pulling Force

Depending on the angle of the slope, the dimensions & size of vessel, a winch and the entire pulley system will be recommended to provide sufficient pulling force.

Ship Repair using Launching Airbags

Most of the process is similar to the airbag ship launching process.

You can read more about it here, but reverse the process.

Instead of launching the vessel into the water, rubber airbags help lift the vessel out of the water, supporting its movement towards land using the winch’s pulling force.

This innovative product helps boost a yard’s ship repair capacity without needing to invest in building another dry dock.

A hard ground is sufficient to enable vessel hauling using airbags, and repair works can be performed at the same location.

The entire hauling process is a delicate case-to-case situation.

MAX’s experience and detailed projections will ensure you a safe ship haul-out process.

These launching bags are also used by our team to solve launch way limitation problems, maximising the return on investment of our clients.



Marine Salvage Section

Marine Salvage is the process/project of recovering a vessel (ship), its cargo, or items after a ship wreck.

This includes towing of a vessel, patching of a ship or re-floating a sunken/grounded ship.

MAX Airbags is a popular product for re-floating a sunken/grounded ship.

Marine salvage using rubber bags are mainly case-to-case studies where MAX technical team will advise only based on known data.

Here is just a general idea of how MAX would assist in vessel salvaging projects:

Buoyancy Needed to Re-float Vessel

The in-depth study & calculations of buoyancy needed will be carried out by MAX.

With this, MAX is able to advise on the size and type of MAX salvaging bags (There are custom made and very different when compared to launching bags with more emphasis on floating ability etc).

Depth or Water Pressure

MAX needs to understand the scale of the project and the magnitude of it to determine the strength & type of mobilisation/re-floating airbags.


We have worked closely with marine salvaging teams in many parts of the world since Hurricane Katrina in 2005.

Our experience in these projects would ensure the success of your marine salvage projects.

So if you’re a marine salvaging team, contact us for high quality and reasonably-priced MAX rubber airbags.

This newly established ship repair yard has limited launch way/slipway. In fact, the slipway has just a solid concrete ground clear of obstacles that is able to accommodate the width of one barge. Conventional wisdom dictates that only one barge can be hauled in for repairs at one time. However, the use of MAX airbags has helped solve this problem.

launchway arrangement

Barge to be brought in to Position A


Haul in First Barge to Position

Firstly, the first 1662 Gross Tonnage barge will be hauled in to Position A using MAX 40 Ton Hydraulic Winch. To identify the pulling force needed for the winch, factors including the sloping angle and the weight of the barge is taken into consideration. In this case, a 40T Hydraulic Winch is enhanced by a 5-lined pulley system to provide the pulling force in excess.

Pulled in using 40T Rated Tension Launchway Winch


Then, at Position A, it is mobilised sideways to Position B using MAX 20 Ton Electric DC Winch facilitated by MAX inflatable bags. Similarly, the use of pulley is installed. The entire process is carried out carefully and under professional supervision.

Safety First

It is very important to avoid sharp objects on the slipway/ground as it may cut the airbags and put the entire operation at risk. The pressure of bags should be checked and maintained at all times. The optional use of excavators & cranes are to ensure the safety of the operations. Communication is a highly regarded aspect in such operations as all parties must be highly diligent for this delicate process. Release Shackle Demo 2

Second Ship for Repairs

Similarly after that, the second barge is also hauled in using the 40T slipway winch into Position A, and moved to Position C using the side 20T winch. This enables the yard to provide repairs for two barges at the same time instead of just one.

Maximise repair capacity by having the third Vessel at the middle 

Moreover, if there was a third barge, it can be brought into Position A and repairs could be carried out there. This way, the one limited slipway will be able to accommodate 3 ships for repairs and maximised the usage of the shipyard’s land.

barge 3 mobilisation

Even accomodate a 3rd barge to maximise yard capacity


Ship Launching

Aside from being used for hauling, the same MAX Rubber Airbags are also used to launch the vessels after repairs. The reverse arrangement is carried out for launching. In fact, launching process is the easier part (compared to hauling) as for barges, an immediate-launch or slow-launch are both acceptable options. However, details like the tide, sloping angle, and the use of certain accessories to facilitate the launch (Quick Release Shackle, for example) would have to be considered.

Embrace Versatility using MAX Airbags

The great thing about MAX mobilisation bags is their versatility. Although in this case, we do not recommend beginner airbag users to carry out such an operation by yourself. Instead, contact our sales team and we would gladly assist in such operations to help you succeed using less costs & maximise your yard’s capacity.

Ship Launching Airbags, the best ship launching method?

Launching a ship is the most important process in ship construction. It not done right, it erases all the hard work building the ship itself. Sometimes, people take ship launching for granted and it came as no surprise that many ship launching projects fail due to negligence.

MAX Turkey 2007 ShiplaunchPenang shiplaunch max airbags

A table for some of the most popular ship launching method comparisons:





Oiled Slideway Launching

(Longitudinal & Side)

Low costs.

Dangerous as front part of the ship undergoes huge pressure. The immediate drop into water also might cause collision with the bottom of the river/sea. Many accidents happen for especially side ship launching.

Oil used will pollute the water.

Roller Slideway Launching

Initial installation costs are high.



MAX Ship Launching Airbags

Very cost-effective. Ship launching airbags can be re-used many times & usually has a lifespan of 5-8 years.

Safe. MAX Ship launching airbags provide support to the hull of the ship and aids its launching motion into the water.


Dry Dock Floating-Out Launching

Initial investment is extremely high.



Mechanical Type Launching

(With mechanical features)

The construction and maintenance for mechanical features are extremely high.

Risky, and only for smaller vessels. You can see many accidents happen for this type of ship launching.



If you are still using oiled slideway ship launching, it may be time to consider a more eco-friendly and safe ship launching method.

If you are launching your ship with dry dock float-out method, consider whether it is necessary for such a huge initial investment for your vessel. The float-out method is great for massive ships (more than 15,000DWT ships) but for ships with a DWT of less than 10,000 tonnes, ship launching airbags can help launch the vessel with relative ease. For those more than 10,000 tonne DWT ship launches, careful projection and a professional team’s assistance may be required. Still, it is usually much more cost-effective than dry dock ship launching. Rubber air bag vessel launching is a much preferred option especially popular in South East Asia, though it is already picking up momentum in many other regions like Europe and North America.

Ship Launching with Rubber Airbags

Ship launching with rubber airbags is an innovative technology that is widely used in the shipping industry. It is said to be introduced by the Chinese for use in emergency launching during the early 1980s. Over the years, ship launching airbags have been embraced by shipping industries in various parts of the world. In fact, MAX Groups Marine has shipped ship launching airbags to 6 continents to date. This technology helps to overcome fixed launching track challenges. This technology has offered flexibility and it saves both time and effort for small and medium-sized shipyards. The technology is reliable, safe and is a good investment for shipyards. This traditional technology was only effective in the launch and landing of small and medium-sized ships but today its application is more versatile in many ways.

Airbag Uses

Ship launching using marine airbags relies on airbags that measure usually from 0.8m to 2.5m in diameter. These airbags usually have lengths from from 5.0m to 25.0m. They are used to launch ships as well as other functions in floating, salvaging and loading. The airbags are popular for launching and landing of chemical tankers and cargo boats. They are also effective for moving and lifting sunken ships or salvaging vessels that are stranded. Shipyards can save in investment expenses with these versatile and portable airbags.

Ship landing for repairs with rubber airbags makes it possible for vessels to land in locations that were previously restricted. Vessels no longer have to land on dry docks. The airbags have been tried and tested for several years and it is now possible to launch ships that weigh between 100 ton and more than 10,000 tonnes.

The outer layer of the airbag is made of rubber and it is designed to protect the cord layers that are inside from external forces such as abrasion. The material used for the outer layer is strong enough to withstand different weather and physical conditions.

The synthetic reinforcement layer is similar to what is found in tires. The cord layers are organized at specific angles so that stress is evenly distributed to offer adequate reinforcement. The airbags also have end fittings, which include a safety air inlet and airtight swivel.

Раздел: Спуск Корабля на Воду

MAX резиноые подушки безопасности являются экономически эффективным решением для спуска различных судов – от небольших барж до крупногабаритных грузовых судов. Но важно понимать, что пневматические ролик-мешки для спуска и подъема судов не является методо, при котором один размер подходит для всех. На самом деле, команда MAX должна понимать все необходимые технические характеристики судна (или конструкции, так как этот метод может быть использован и для спуска кессонов, плавающих причалов и т.д.) и принимать во внимание внешние факторы.

Первый шаг заключается в определении размера и объёмов.

Определение основных размеров и типа судов

В MAX мы сначала слушаем, и только потом говорим.

Перед консультацией наши сотрудники, как правило, просят вас заполнить некоторые технические формы по характеристике. Такие факторы, как общая длина (LOA), балка, проект, вес спуска (легкий вес) судна и рабочая высота (расстояние между землей и корпусом судна) будут учитываться. Это позволяет нашей команде оценить вес конструкции во время спуска на воду и узнать основные размеры для того, чтобы эффективно структурировать резиновые подушки безопасности. Различные конструкции играют важную роль при выборе типа надувных резиновых подушек безопасности.

Линейка товаров MAX пневматических ролик-мешков для спуска и подъема судов

После определения типа судна и его основных размеров, мы сможем дать вам совет по типам, размерам и количеству надувных подушек безопасности. Вес, определяемый по проценту от массы судна,также принимается во внимание. Это помогает MAX обеспечить безопасный процесс спуска на воду, не перегружая резиновые подушки безопасности, а также создать запас прочности, так как во время спуска кораблей на воду переносится дополнительный вес судна.

На основании размеров и структурного проекта команда может помочь вам советом о размерах резиновых подушек безопасности с точки зрения длины, диаметра и типа. Затем, на основании расчетов и тщательных прогнозов, мы можем определить гарантированную несущую способность надувных подушек безопасности. В этот момент дополнительные пневматические ролик-мешки будут включены в наши рекомендации.

Процесс спуска также проверяется нашим программным обеспечением “MAX Smart Ship launching”.

launching calculator

В связи с профессиональным конкурентным преимуществом этот скриншот только часть программного обеспечения.

Это программное обеспечение разработано нашей командой разработки программного обеспечения и дважды проверяет наши расчеты, чтобы убедиться, что рекомендуемый тип и количество являются оптимальными.

Подготовка конструкции на земле

MAX пневматическому ролик-мешку для спуска требуется твердая повехность, чтобы вся конструкция не утонула во время запуска.

Если земля мягкая или состоит из плавучего песка, то существует много вариантов, которые наши сотрудники смогут вам порекомендовать. Мешки с песком – широко используемый вариант. Мы также помогли многим нашим клиентам подготовить землю для спуска стапель. Это потребует очень детального изучения природы земли и углубленного анализа на индивидуальной основе. Этот аспект не следует упускать из виду. Мы помогаем нашим клиентам решить эти проблемы в течение многих лет на основе нашего опыта в спуске кораблей. Свяжитесь с нами, если вы столкнулись с проблемами при спуске стапеля.

Другие условия предварительного запуска и проблемы энергетики , в том числе проектирование и поставку дизель-генераторных установок будут обсуждаться с клиентом.

Выбор лебедки

Усилие, необходимое для поддержки движения судна в воду, определяется с учетом угла наклона и веса. Команда должна определить тип и силу стапельной лебедки, необходимую для сохранения конструкции на месте. Выбор между электрической и гидравлической лебедкой типа также важно. Тали и необходимые оснастки оборудования также будет рекомендованы, если это необходимо.

Наличие сильной лебедки, которая способна обеспечить достаточное тяговое усилие, является жизненно необходимым. Это особенно важно для некоторых спусковых проектов, которым требуется лебедка с длительным сроком службы.

Размещение резиновых подушек безопасности

Мы используем 3D проекции, чтобы определить размещение резиновых подушек безопасности на стартовой позиции.

спуск на воду

Этот 3D вид помогает понять, как распределить вес судна / конструкции равномерно для максимальной безопасности. MAX принимает во внимание расстояние между компонентами и способы координации места “блоков поддержки”.

3D печать используется также для некоторых проектов.

Спуск корабля

В первый раз, как правило, клиентам требуются услуги нашей консультационной команды и её присутствие на месте для оказания помощи при спуске судна на воду. Мы можем содействовать всему процессу подготовки, а также наблюдать за процессом спуска для наших клиентов за небольшую оплату нашей консультации. С многолетним опытом и тщательными прогнозами наша команда гарантирует успех проекта и безопасность экипажа. Имея многочисленные преимущества, спуск конструкций до 10000 тонн с использованием этого метода, довольно распространён в наши дни. Широко признано, что эти резиновые мешки безопасности могут быть использованы в течение долгих лет и являются гораздо более экономически эффективными по сравнению с другими традиционными методами спуска кораблей на воду.

Это простая иллюстрация процесса спуска катера на воду при помощи резиновых подушек безопасности. Все начинается со удерживанием корабля на месте при помощи лебедки, когда резиновые подушки безопасности расположены между корпусом судна и землей, а затем надуваются. Когда лебедка включена, трос медленно разматывается, и конструкция может скользить по направлению к береговой линии при помощи силы тяжести. В назначенном пункте связь между лебедкой и судном будут сокращена с помощью “быстрого выпуска скоб”. Судно при помощи силы тяжести и пневматических ролик-мешков для спуска и подъема судов будет безопасно запущено в море. Это метод с минимальным риском. Пожалуйста, обратите внимание, что существует множество различных сценариев, чтобы соответствовать конкретной ситуации и судну, так что это всего лишь общее представление о методе спуска. Для консультации по вашему проекту, напишите нам, чтобы наша команда смогла вам помочь.

Раздел: Судоремонт

Как и метод спуска кораблей, понятие и способы подготовки очень похожи, только процесс происходит в обратной последовательности. Наличие достаточного тягового усилия (в данном случае, перетяжка лебедки) является ключом к поддержанию стабильного процесса судоремонта.

Понимание основных размеров и веса судна

Аналогично процессу спуска судна, установка судна для ремонта требует от нашей команды тщательного анализа размеров судна. Вес, общая длина и ширина корабля – это только некоторые из аспектов, на которых наша инженерная команда будет сосредоточена. Различия конструкции, то есть дизайн корпуса и корабля, могут повлиять на виды резиновых подушек безопасности, которые будет необходимо использовать.

Выбор подходящих MAX резиновых подушек безопасности

Основные размеры и структурная конструкция судна позволяют нашей команде рекомендовать размеры, толщину спецификации и количество необходимых резиновых подушек безопасности. При выборе наиболее подходящих подушек для перевозки, безопасность является нашим приоритетом номер один. Тяжелые аварийные подушки безопасности для подъёма не должны быть перегружены. Вот почему опытные технические специалисты MAX добавляют процент от веса в чрезвычайных ситуациях к расчетам. Это позволит применить “резиновую подушку безопасности” к любому лишнему весу судна.

Затем, подробные прогнозы и тщательные расчеты позволяют определить несущую способность резиновых подушек безопасности. Эта цифра в дальнейшем используется, чтобы определить общее количество необходимых подушек, в том числе дополнительных подушек для мобилизации. Наша команда использует наше собственное программное обеспечения “MAX Smart Ship Launching” для перепроверки расчетов.

Тяговая лебедка / тяговые лебедки с достаточным тяговым усилием

В зависимости от угла наклона, объёма и размера судна, вам будут предоставлены рекомендации, чтобы лебедка и вся система такелажа, усиланная шкивами, обеспечивали достаточное тяговое усилие.

Судоремонт с помощью спуска резиновых подушкек безопасности

Большая часть процесса аналогична процессу с пневматическими ролик-мешками для спуска и подъема судов. Вы можете узнать больше об этом здесь. Вместо спуска судна в воду, резиновые подушки безопасности помогут вывести судно из воды, двигаясь по направлению к земле вместе с использованием тяговой лебедки.

Этот инновационный продукт помогает повысить судоремонтный потенциал предприятия без необходимости инвестировать в строительство дополнительного сухого дока. Достаточно жесткой земли для того, чтобы судно перевозилось с использованием резиновых подушек безопасности для ремонтных работ. Весь процесс вывозки – это детальное рассмотрение ситуации в зависимости от конкретного случая. Опыт MAX и подробные прогнозы обеспечат безопасный процесс ремонта корабля.

Раздел: Морское Аварийное Спасение

Морское аварийное спасение – это процесс/проект восстановления судна (корабля), его груза или предметов после крушения судна. Включает в себя буксировку судна, латание судна или подъем затонувших /заземленных кораблей. MAX тяжелые аварийные подушки безопасности для подъёма являются популярным продуктом для подъема затонувших / заземленных кораблей. Морское аварийное спасение происходит при помощи резиновых подушек безопасности, но в ависимости от конкретного случая наша техническая команда предоставляет консультации на основе известных фактов. Далее мы хотим дать вам основное представление о том, как мы оказываем помощь в утилизации судов.

Поплавки, необходимые для поднятия судна

Будут проведено исследование и подготовлены расчеты поплавков, которые будут необходимы на глубине. При этом MAX способен консультировать по размеру и типу MAX тяжелых аварийных подушек безопасности для подъёма (разработка производится по заказу, они существенно различаются от подушек для спуска с большим упором на плавающую способность и т.д.).

Глубина или давление воды

MAX должны понимать масштаб проекта и его величину, чтобы определить силу и тип мобилизационных / плавающих резиновых подушек безопасности.

Мы тесно сотрудничаем с командами по морской утилизации во многих частях света, поскольку ураган Катрина в 2005 году добавил нам опыта в этих проектах, и мы сможем обеспечить успех ваших морских спасательных проектов. Если вы представляете команду по морской утилизации, свяжитесь с нами для получения MAX тяжелых аварийных подушек безопасности для подъёма высокого качества и по разумным ценам.

Sección de botadura de barcos

Las bolsas de aire de caucho MAX son una solución rentable para las botaduras de buques, desde aquellos de menor tamaño hasta los enormes barcos de carga. Pero es muy importante entender que el lanzamiento bolsas no es un método “universal”. De hecho, el equipo de MAX necesitará entender todas las especificaciones técnicas del buque (o estructura, debido a que este método de lanzamiento también puede utilizarse para lanzar cajones y muelles flotantes, etc.) así como muchos factores externos.

El primer paso es identificar el tamaño y las dimensiones de la estructura.

Identificando las principales dimensiones y tipos de buques

En MAX, creemos en la escucha antes de hablar.

Antes de brindar asesoramiento, nuestro personal normalmente solicitará a los prospectos que completen un formulario de especificaciones técnicas. Se deberán especificar, solamente por nombrar algunos, factores como la longitud total, el ancho máximo, el casco, el peso del lanzamiento (peso ligero) del buque y la altura de trabajo (distancia entre el suelo y el casco de la embarcación). Esto permite a nuestro equipo entender el peso de la estructura durante el lanzamiento y es igualmente importante saber las principales dimensiones con el fin de que las bolsas se puedan estructurar de forma eficiente. Los diferentes diseños de la estructura juegan un papel en la elección de los tipos de tubos inflables.

Selección de la bolsa de aire MAX

Después de comprender el tipo de buque y sus dimensiones principales, entonces podremos recomendar los tipos, tamaños y número de bolsas marinas. Será tomada en consideración un cierto porcentaje de peso de contingencia del barco. Esto ayudará a MAX a garantizar un proceso de lanzamiento seguro al no aplicar fuerza excesiva en las bolsas así como para mantener un margen de seguridad, por lo que no deberá haber ningún peso adicional en el buque durante el botadura.

Basándose en las dimensiones y diseño estructural, el equipo puede recomendar las dimensiones de la bolsa de aire de caucho en términos de longitud, diámetro y tipo. Posteriormente, en base a cuidadosos cálculos y proyecciones, podremos determinar la capacidad de carga garantizada por cada bolsa marina de aire. En este punto, serán incluidos tubos inflables adicionales para la movilización en nuestras recomendaciones.

El proceso de selección también es revisado por nuestro software MAX Smart Ship launching.

launching calculator

Debido a la ventaja competitiva profesional, esta es una captura de pantalla de solamente una parte del software.

Este software fue desarrollado por nuestro equipo interno de ingeniería de software y nuestros cálculos fueron doblemente verificados para asegurar que el tipo y la cantidad recomendada sea óptima.

Preparación de la Estructura en Tierra

El proceso de lanzamiento de las bolsas de aire de MAX requiere un terreno firme con el fin de que la estructura no se hunda durante el lanzamiento.

Si el terreno es blando o es de arena sumergible, hay muchas opciones que recomendará nuestro personal. Los sacos de arena son una opción muy utilizada. También hemos ayudado a muchos de nuestros clientes a preparar suelo de concreto, como en el lanzamiento de gradas. Esto requiere un estudio muy delicado de la naturaleza del suelo así como un análisis de la profundidad que se hace sobre las bases de caso por caso. Este aspecto no debe pasarse por alto. Hemos ayudado a nuestros clientes a resolver estos problemas en nuestros muchos años de experiencia en botaduras de barcos. Póngase en contacto con nosotros si tiene estos problemas difíciles con la el lanzamiento de gradas.

Otras condiciones previas al lanzamiento como problemas de generación de energía , incluyendo el diseño y suministro de sistemas de generador diesel también se discutirán con el cliente.

Selección de los Cabestrantes

La fuerza necesaria para soportar el movimiento de la embarcación en el agua se determina considerando el ángulo de inclinación y el peso. El equipo debe de determinar el tipo y la fuerza del cabestrante de la grada que se necesitan para mantener la estructura en su lugar. Es importante para determinar si se debe utilizar cabrestante eléctrico o hidráulico. Los motones y los equipos de aparejos necesarios también son recomendados en caso de ser necesarios. Contar con un cabrestante fuerte, capaz de proporcionar la suficiente fuerza de tracción es vital. Esto es especialmente cierto para determinados proyectos de lanzamiento que requieren que el cabrestante opere durante largos períodos.

Colocación de las Bolsas Marinas

Utilizamos proyecciones en 3D para determinar la colocación de las bolsas de aire de caucho en la posición de lanzamiento.

спуск на воду

Esto ayuda a dar una vista en 3D sobre cómo distribuir uniformemente el peso del buque/estructura para máxima seguridad. MAX toma en cuidadosa consideración la distancia entre los componentes y la forma de coordinar las locaciones de los “bloques de apoyo”. La impresión 3D también se usa para algunos proyectos.

Пневматические ролик-мешки для спуска и подъема судов

La Botadura

La primera vez que trabajamos con un cliente, usualmente es requerido que consulte con nuestro equipo para que estemos en tierra con el fin de ayudar a lanzar su buque. Podemos facilitar para nuestros clientes toda la preparación junto con la supervisión del proceso de lanzamiento con un pequeño costo de la consulta. Estamos equipados con décadas de experiencia y proyecciones cuidadosas, nuestro equipo asegura el éxito del proyecto y la seguridad de la tripulación. Con estas ventajas, el lanzamiento de estructuras de hasta 10.000 toneladas que utilizan este método es bastante común en estos días. Es ampliamente reconocido que estas bolsas pueden utilizarse por muchos años y esta técnica es mucho más rentable en comparación con otros métodos tradicionales de botadura de buques.

Esta es una simple ilustración del proceso de botadura. Comenzó con un cabestrante sosteniendo el buque en su lugar cuando se posicionaron las bolsas marinas entre el casco del barco y el suelo y posteriormente se procedió a inflar. Cuando se enciende el cabrestante, el cable de alambre se desenrolla lentamente y se le permite a la estructura deslizarse hacia la línea de mar con la ayuda de la gravedad. En el punto designado, la conexión entre el cabrestante y buque será cortada utilizando un “grillete de liberación rápida”. La embarcación, asistida por la gravedad y los tubos inflables de lanzamiento, se lanza al mar de forma segura. Este es un método con riesgo mínimo. Sin embargo, tome en cuenta que existen muchos escenarios diferentes para abordar diferentes situaciones y diferentes buques, así que esto es solamente una idea general. Para sus proyectos, envíenos un email para que nuestro equipo puede ayudar.

Sección de reparación de barcos

Al igual que el método de botadura de buques, los conceptos y procesos de preparación son a la vez muy similares, pero invertidos. Tener la suficiente fuerza de tracción (en este caso, el cabestrante de arrastre) es la clave para mantener un proceso de arrastre firme para la reparación de los buques.

Entendiendo las Principales Dimensiones y el Peso de la Embarcación

De forma similar a los procesos de lanzamiento de barcos, el arrastre de un buque para proyectos de reparación requiere que nuestro equipo analice sus dimensiones en detalle. El peso ligero y la longitud y el ancho total del barco son algunos de los aspectos en los que se enfoca nuestro equipo de ingeniería. Las diferencias estructurales, es decir, el diseño del casco y la nave pueden afectar los tipos de bolsas utilizadas.

Eligiendo las Bolsas de Aire MAX Adecuadas

Las principales dimensiones y el diseño estructural de la embarcación ayudan a nuestro equipo a recomendar las dimensiones, espesor, características y número de bolsas marinas necesarias. Al elegir los tubos inflables más adecuados para el transporte, la seguridad es nuestra principal prioridad. Las bolsas de aire de caucho no deben sobrecargarse. Es por eso que los experimentados técnicos de MAX añaden un porcentaje de peso de contingencia en los cálculos. Esto agrega un “colchón de seguridad y adicionalmente sirve para acomodar el exceso de peso que el buque pudiera haber añadido

Posteriormente, las proyecciones detalladas y los cuidadosos cálculos nos permiten identificar la capacidad de la carga por bolsa. Esta cifra se utiliza después para deducir el número total de bolsas marinas necesarias, incluyendo los tubos inflables adicionales para la movilización. Entonces, nuestro equipo utiliza nuestro propio software desarrollado en casa MAX Smart Ship Launching para realizar una doble revisión de los cálculos.

Cabestrante de Tracción / Cabrestrante de Arrastre con Suficiente Fuerza de Tracción

Dependiendo del ángulo de la pendiente, las dimensiones y el tamaño del buque, se recomendará un cabrestante y el sistema de aparejo mejorado por poleas con el fin de proporcionar la suficiente fuerza de tracción.

Reparación de Buques Utilizando Bolsas de Aire de Lanzamiento

La mayor parte del proceso es similar al lanzamiento de barcos con bolsas. Puede aprender más del tema aquí. En vez de lanzar el buque al agua, las bolsas de aire de caucho ayudan a elevar la embarcación fuera del agua, apoyando su movimiento hacia el suelo cuando se utiliza junto con un cabrestante de tracción.

Este innovador producto ayuda a aumentar la capacidad de reparación de los astilleros sin necesidad de invertir en la construcción de otro dique seco. Un suelo duro es suficiente para permitir el transporte de la estructura utilizando los tubos iflables para los trabajos de reparación que se vayan a realizar. El proceso completo de acarreo es una situación delicada que se evalúa caso por caso. La experiencia y proyecciones detalladas de MAX garantizarán un proceso de reparación de buques seguro.

Sección de Salvamento Marítimo (operación flotante)

El salvamento marítimo es el proceso/proyecto de recuperación de buques (barcos), su carga, o los artículos después de un naufragio. Esto incluye el remolque de un buque, colocar un parche a un barco o hacer que reflote un barco hundido/ detenido en tierra. Las bolsas de aire de MAX son un producto popular para que vuelva a flotar un barco hundido/ detenido en tierra. El salvamento marítimo utilizando bolsas de aire de caucho son principalmente estudios de caso a caso en el que nuestro equipo técnico le asesorará únicamente en base a hechos conocidos. Esta es solamente una idea de cómo ayudamos en los proyectos de salvamiento de buques.

Flotabilidad Necesaria para Reflotar Embarcaciones

Se lleva a cabo un estudio a profundidad y los cálculos de flotabilidad necesarios. Con esta información, MAX puede asesorar sobre el tamaño y el tipo de bolsas de salvamento MAX (Están diseñadas a la medida y son muy diferentes en comparación con el lanzamiento de bolsas, con más énfasis en la capacidad flotante, etc.)

Profundidad o Presión del Agua

MAX necesita entender la escala del proyecto y la magnitud del mismo para determinar la fuerza y el tipo de movilización/ bolsas de aire para reflote.

Hemos trabajado en estrecha colaboración con equipos de salvamiento marítimo en muchas partes del mundo desde el huracán Katrina en el 2005. Nuestra experiencia en estos proyectos asegurará el éxito de sus proyectos de salvamento marítimo. Así que si usted gestiona un equipo de salvamento marítimo, póngase en contacto con nosotros para obtener alta calidad y precios razonables en las bolsas de aire marinas MAX.
