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

An essential task nowadays for the global shipping industry would be to reduce its environmental impact, an attempt that will require a multipronged approach. But that is no simple task. According to experts, marine engines are complex to alter, and even if engineers can change them in a manner that will make them emit less CO2, changing shipping fleets will be very costly. Hence, progress is slow in this domain. However, a number of shipping companies like DP World Russia, are making impressive changes and striving to make solutions that decrease co2 emissions. Plus they are slowly putting those changes to work on their fleets of ships. They have been increasingly meeting the benchmark requirements of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating effectiveness in the commercial shipping sector. A great example of technical progress is seen into the improvement of the Mewis duct. This is a cylindrical channel which has integrated fins, that will be located in the front of the propeller. As the a ship moves through the water, it produces a wake current which can be turbulent and result in power wastage. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines the water flow. Additionally, the fins in the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency of the propulsion system.

Several shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run using liquified gas (LNG), that is the absolute most higher level and fuel-efficient solution available. These vessels include 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 fuel because of slight heat rises, which in turn causes boil-off to occur. To make these vessels even more environmentally friendly, they have been fitted having an advanced level exhaust recirculation system that significantly decreases nitrogen oxide emissions. Additionally, the ships have a gasoline combustion system that decreases the potential of emitting methane into the atmosphere.

Some shipping companies are utilising self polishing coatings on the hulls of the vessels. This, based on maritime professionals, helps prevent marine organisms from clinging onto the hull where they result in a significant drag. When ships are able to eradicate this drag utilising the coating, they could also help to make their vessels more efficient. There are many efforts to boost a ship's efficiency, which range from complex engineering methods to easy things like changing bulbs. As an example, vessels can save energy and start to become more environmentally friendly by replacing conventional incandescent LED lights with Light-emitting Diode lights, which consume less electricity and last for decades.
