International Maritime Organisation (IMO) has been intensifying their efforts in environmental rule-making in recent years. This no doubt drives the entire industry in an inevitable direction – to greener, cleaner solutions. As a result, ships and ports are demanded to be more ‘green’ these days. Green ships consist of elements from cleaner fuels to various green ship technologies to minimise energy wastage, carbon output and seek to decrease negative impact on marine biology.
Green ship is about marine biology, cleaner fuels, and energy wastage minimisation. Tweet this!
Ships used to run on unrefined crude full with sulphur and environmentally-harmful impurities. This is because this type of fuel is the leftover of the oil refining process and extremely cheap when compared to other options. In 2005, the IMO started to control the sulphur content of maritime fuel especially in Western countries like the U.S. and Europe. This results in ships needing to burn higher quality (hence, more expensive) fuel with components similar to diesel.
Technologies of greener ships are in demand right now due to more and more regulations and public awareness of the environment.
Some of the most talked about green ship technology is the No Ballast System that aims to minimise ship ballast’s negative environmental impact on aqua organisms.
No Ballast System decreases negative impact on aqua biology.
More efficient systems like higher propulsion efficiency and better cooling water systems that drastically decreases environmental effects are also in the making. Solar cell integration is also one big area that shipbuilders are focusing on.
Efficient solar cell integration in greener ships can save fuel up to 20%.

Besides green ships, port development projects are also more eco-friendly these days. Ports are focusing on reducing carbon footprints, minimising pollution, conserving natural resources and strive for zero energy wastage. Some even placed great emphasis in decreasing noise pollution!

Most ports go green by first identifying recycling possibilities (or re-use even) and put a solid waste segregation plan in action.
The ‘green’ vision of ports has prompted the implementation of carbon reduction programs that includes monitoring of gas, electricity and water usage in ports. Energy saving systems like smart lighting systems are also practised in certain port projects.
Long-term Future of Green Ports & Green Ships
Going ‘green’ is not exactly achievable overnight. It takes lots of effort from all authorities and parties involved. Until now, implementation of more environmental friendly and ‘green’ systems are hindered by the costs involved. However, the energy consumption in the long-term may be a great investment. ‘Green’ is not going anywhere soon, so it is highly advisable that even the smallest companies in this industry will be prepared for the ‘Green Era’. No matter how small the contribution is, steps taken to reduce carbon footprints and implementation of more eco-friendly programs will help build a more sustainable future for the industry.
That is why MAX Groups Marine focuses a lot on reducing our carbon footprint from our sales office to manufacturing plants. Because we care. For us, going green is a priority.
