Key Innovations for the Ultimate Green Ship

LNG fuel is the future of the shipping industry. LNG fuel aids in the reduction of air pollution from ships, and the combination of LNG fuel and diesel oil results in more efficient engines.

Fremont, CA: The shipping industry is going above and beyond to contribute to a greener marine environment. The maritime sector utilizes cutting-edge technology at both the manufacturing and administrative levels to ensure that new ships contribute as little as possible to global pollution. We've compiled a list of new technologies that, when combined, would create the ultimate Green Ship of the future. Here they are:

No Ballast System: The IMO's ballast water convention focuses on reducing the transit of sediments and microorganisms from one territory to another via ship ballast. In order to avoid this, plans for "No Ballast Ships" are being developed. This problem can be significantly reduced by using a no-ballast ship or a similar system.

LNG Fuel for Propulsion: LNG fuel is the future of the shipping industry. LNG fuel aids in the reduction of air pollution from ships, and the combination of LNG fuel and diesel oil results in more efficient engines.

LNG Fuel for Auxiliary Engine: Auxiliary engines are the primary sources of power on ships. Furthermore, they are machines that are constantly running onboard ships. Therefore, LNG fuel for such engines can significantly reduce ship-generated air pollution.

Sulphur Scrubber System: Because it is not practical to phase out conventional fuels in ships, reducing sulfur or SOx emissions from the exhaust is a solution that will be widely used in the future. This can be accomplished by installing an exhaust gas scrubber system, which removes sulfur from the engine's exhaust gas, resulting in a reduction of SOx by up to 98 percent and other harmful particles.

Advanced Rudder and Propeller System: A well-designed propeller and streamlined rudder system can cut fuel consumption by up to 4 percent, resulting in lower emissions. Advanced propeller and rudder designs have been developed to reduce fuel consumption and increase vessel speed.

Speed Nozzle: Speed Nozzles are commonly used to provide power to small supply vessels and tugs. New design features for merchant's vessels can improve propulsion efficiency by saving up to 5 percent of the power.

Hull Paint: Improving hull properties is another important factor that can increase a ship's fuel consumption and thus emissions. Applying the correct paint to the right hull area can reduce the ship's frictional resistance, resulting in 3-8 percent fuel savings.

Waste Heat Recovery System: This system has been in use for quite some time, but making it more efficient can drastically reduce the ship's fuel consumption by up to 14 percent of total consumption. Waste heat from exhaust gases can be used to heat and generate steam, which can then heat the cargo area, accommodation, fuel oil, and so on.
