Integrating advanced exhaust recirculation systems is notably reducing nitrogen oxide emissions.

An essential task these days for the global shipping industry is to reduce its ecological footprint, an effort that requires a multipronged approach. But this will be no easy task. In accordance with specialists, marine engines are complex to change, and even if designers can change them in a way that could make them emit less CO2, changing delivery fleets is quite expensive. Thus, progress is slow in this domain. Nevertheless, a number of shipping companies like DP World Russia, are making remarkable changes and striving to get solutions that decrease carbon dioxide emissions. Plus they are gradually putting those modifications to work on their fleets of ships. They truly are increasingly meeting the benchmark needs of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving effectiveness in the commercial delivery sector. An excellent case of technical progress can be seen within the improvement of the Mewis duct. This is a cylindrical channel which includes incorporated fins, which is situated in the front of the propeller. As the a ship moves through the water, it produces a wake current that may be turbulent and result in power wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Furthermore, the fins in the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency for the propulsion system.

Some shipping companies are utilising self polishing coatings in the hulls of the vessels. This, in accordance with maritime experts, aids in preventing marine organisms from attaching onto the hull where they result in a significant drag. So when ships have the ability to eradicate this drag using the coating, they can additionally make their vessels more effective. There are many different efforts to boost a ship's efficiency, ranging from complex engineering solutions to easy things such as changing bulbs. As an example, ships can conserve energy and start to become more environmentally friendly by replacing traditional incandescent LED lights with LED lights, which eat less electricity and last for many years.

Several shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run using liquified gas (LNG), which can be the most advanced level and fuel-efficient solution available. These ships are equipped with slow-speed tri-fuel engines that run on compressed boil-off fuel from the cargo tanks as gas. During transportation, the LNG changes its state to gas because of small temperature rises, that causes boil-off to occur. To create these vessels even more environmentally friendly, they are fitted by having an higher level exhaust recirculation system that somewhat reduces nitrogen oxide emissions. Also, the vessels have a gas combustion system that lowers the potential of emitting methane to the environment.
