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.
You can now safely launch a ship, haul in vessels for repairs or perform mobilisation projects in a more cost effective way.
MAX Airbag Launching is a safe, versatile & reliable option with a much lower capital investment.

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.
(Example of ISO14409 rubber airbag category product)
(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.
Why
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.
MAX. Your Most Reliable Marine Equipment & Airbag Ship Launching Solution.
At MAX, we focus on delivering value as our Managing Director always says, “product quality is the No.1 marketing”. The team will continue to hold this statement true to heart, always.
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)
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.
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. MAXNEVER 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.
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!
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.
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.
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.
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.
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.
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.
This is a simple breakdown of the common air bag launching process.
It started with a winch holding the vessel in place.
Airbags are placed underneath the ship’s hull.
Air bags are then inflated.
The transfer of weight from support blocks to having the airbags actually lifting the vessel itself.
Remove the support blocks.
Then the winch’s pulling force is slowly decreased to enable mobilisation of vessel towards the sea line.
At a certain point, the connection between winch and vessel will be released using MAX quick release shackle.
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.
View a Youtube video of the launching of Sealink Asia 101 by MAX below:
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, specs & number 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.
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.
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.
Straight Sideways Mobilisation with MAX Inflatable Bags
Country: Indonesia.
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.
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.
20T Winch for Sideways Mobilisation
1st Vessel in Position B
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.
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.
Second vessel brought in with MAX bags and Hydraulic Winch
Vessel 2 in central position
Pulled Sideways using 20T DC Winch
2 Barges for Repairs 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.
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.
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.
A table for some of the most popular ship launching method comparisons:
METHOD
COST
SAFETY
ENVIRONMENT
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.
Moderate.
Eco-Friendly
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.
Eco-Friendly
Dry Dock Floating-Out Launching
Initial investment is extremely high.
Safe.
Eco-friendly
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.
Eco-friendly
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.

Here’s what makes our airbags special:
MAX Groups Marine has launched various types of vessels in 6 continents using marine airbag technology. For more info of our projects, visit <http://max-groups.com/projects/>
MAX Marine Airbag technology is a flexible technology where it can handle heavy structure launchings (ships, boats, floating jetties, caissons), ship repair haul-ins and marine salvaging cases…[Read More]
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.
Ship Launching Airbag Features
Ship launching with rubber airbags is made possible through the use of specially designed airbags. These airbags are made of rubber layers and synthetic-cord-reinforced rubber layers. The two layers are vulcanized and air is compressed inside them to allow them to roll.
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.
Benefits of Ship Launching with Rubber Airbags
The rubber airbags used for ship launching application is an innovative technology with a main aim to improve efficiency. At MAX Groups Marine, only high quality raw materials are used to produce the airbags. This material has attained the ISO standard.
Ship launching with rubber airbags is a cost effective solution and the airbags can be used for 7 to 15 years with reasonable maintenance and care.
The quality and safety of the airbags is guaranteed and this is a significant advantage for the shipyards. The airbags have been tested in the laboratory and in the field to ascertain their effectiveness and safety. Shipyards can get free consultation during the design process to ensure they get airbags that meet their unique individual requirements.

Ship launches require lots of planning and the launch of a ship is the proudest moment for both the shipowner & the crew who built it. Regardless of its size, building a vessel is a great deal of engineering work. We appreciate awesome engineering works at MAX so here we are, just sharing some of our favourite ship launching videos.

Окончательное Руководство по спуск кораблей на воду, судоремонту и ликвидации аварий с использованием пневматических ролик-мешков
В настоящее время предприятия должны быть гибкими и иметь высоко-универсальное оборудование, чтобы адаптироваться к постоянно меняющейся экономике. Технология MAX резиновых подушек безопасности является чрезвычайно гибкой морской технологией, она может поднимать тяжелые конструкции (корабли, катера, плавающие причалы, кесисоны), судоремонтные дальнемагистральные модули и морские аварийные спасательные блоки.
Все, что вам нужно, это стапель без каких-либо острых предметов; стапель-лебедка, чтобы обеспечить необходимое тяговое усилие, система такелажа со стальным тросом, шкивом, кандалами; и несколько резиновых подушек безопасности. Спущенные резиновые подушки безопасности вставляются под корпус и накачиваются, чтобы поднять конструкцию. MAX надувные резиновые подушки безопасности разработаны с большой несущей способностью и облегчают спукс судна на воду (или его подъём из воды, в зависимости от трубований), используя свою способность к скручиванию.
Популярные способы применения:
Торговые суда общего назначения: Первый в истории спуск корабля с помощью пневматического ролик-мешка прошел в Турции, судно 8600DWT OFMAR Атасой было запущено в Стамбуле при помощи подушек и полной технической поддержки от MAX в 2007 году.
Баржа: Баржи часто заземлены (особенно в Юго-Восточной Азии) и спускаются на воду при помощи надувных резиновых подушек безопасности, а не другими способами, так как это наиболее универсальный и экономически эффективный метод.
Резиновые подушки безопасности предназначены для всех типов судов, весом менее 10 000 тонн в том числе и легких судов, но не ограничиваясь якорными буксирными судами снабжения, танкерами, химическими танкерами, плавучими доками, тяжелыми сельскохозяйственными сооружениями, строительными кессонами и т.д.
Мы занимаемся всеми проектами – от начальной консультации до завершения работ, а также поставками лебедок, аксессуаров, резиновых подушек безопасности, чтобы убедиться в хорошей скоординированности и спецификации на месте запуска. Мы помогли многим компаниям по всему миру снизить затраты на спуски кораблей и ремонт проектов, просто напишите нам, и мы будем рады вам помочь!

Хотя мы и не можем раскрывать подробности расчетов в связи с профессиональной конкуренцией, это руководство стремится создать общее представление о том, что MAX советует своим клиентам.
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.
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”.
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.
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.
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”.
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.
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.
