The shipping industry often finds itself in the line of fire when it comes to environmental safety. However, the industry has been making progress and continuous efforts are being made by the stakeholders to control its carbon footprint.

Among the various measures including guidelines, advisories and regulations, there are several technological advancements which are pushing the sector towards a greener future.

Here is a list of 10 technologies that are assisting the maritime to Go Green:

1. Ballast Free Ships: A No Ballast Ship can drastically improve the problem of transmission of sediments and micro-organisms of one region to another. IMO's Ballast Water Convention strictly focusses on this issue. With Ballast Free Ships, the shipping industry is looking forward to addressing an important environmental concern. Ballast free ships will result in blocking the transmissions and terminating other requirements like sterilization of equipment that are costly.

2. Scrubbers: While alternative fuels are being looked upon as future fuels, use of conventional fuels cannot be phased out. Hence, scrubber technology becomes an important technology for the shipping industry. Sulphur Scrubber Systems can reduce SOx emissions by 98% along with controlling the emission of other harmful particles.

3. Advance Rudder and Propeller Systems: By reducing fuel consumption, the shipping sector can improve its energy efficiency. An advanced rudder and propeller system can allow a reduction in fuel consumption, reducing emissions up to 4%.

4. Speed Nozzle: Speed Nozzle in trading ships can save power up to 5% and hence improve propulsion efficiency of ships. Technology is playing a crucial role in modifying the designs of speed nozzles and hence ultimately achieve greater efficiency.

5. Waste Heat Recovery System: This system is already in use within maritime for quite a long time. However, efforts are being made to improve the Waste Heat Recovery System to gain better fuel efficiency of ships and reduce fuel consumption. An effective Waste Heat Recovery System can reduce 14% fuel consumption, making it a reliable and long-term solution for achieving better fuel efficiency.

6. Exhaust Gas Recirculation: This is another technology that is playing a pivotal role in controlling NOx emissions. Up to 80% reduction in NOx emission has been observed by using EGR systems.

7. Advanced Pump and Cooling System: Decreased resistance in the flow can be achieved by a modern pump and cooling system. These systems can save 20% of electric power of the vessel.

8. Green Propulsion Systems: Green propulsion systems like Sail and Kite Propulsion System, Fuel Cell Propulsion or Solar Propulsion Systems are now making their way in the shipping industry. When used along with conventional propulsion systems, green propulsion systems can drastically reduce the emissions by 35% plus save on fuel usage as well.

9. Sandwich Plate System: In Sandwich Plate System, two metal plates are composted together by polyurethane elastomer core bond. The system is of great help in improving design of vessel as it makes the structure light in weight and less prone to corrosion. Better service performance and easy maintenance are added advantages.

10. Improved Steering Gears: Latest innovations have allowed the manufacturers to come up with more efficient steering gears, which are also eco-friendly and economical. With modified steering gears, up to 4% reduction in the ship's fuel consumption can be easily achieved on a single voyage.

In addition to the aforementioned technologies, LNG fuel, hull paint and adding water to fuel are other ways that are being adopted by the shipping industry to make shipping more environment-friendly.

Therefore, it would not be an exaggeration to assert that 'Technology', today, is effectively cruising maritime towards a greener future.
