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

A significant task nowadays for the global shipping industry is to reduce its ecological footprint, an attempt that needs a multipronged approach. But that is no easy task. Based on specialists, marine engines are complex to alter, and even if designers can modify them in a manner that will make them emit less CO2, modifying delivery fleets will be pricey. Thus, progress is sluggish in this domain. Nevertheless, a number of shipping companies like DP World Russia, are making amazing modifications and striving to get solutions that decrease co2 emissions. Plus they are gradually putting those changes to the test on their fleets of vessels. They truly are increasingly fulfilling the benchmark demands of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving effectiveness in the commercial shipping sector. A great case of technical progress is visible in the enhancement of the Mewis duct. This is a cylindrical channel which includes integrated fins, that will be situated in the front of the propeller. As the a ship moves through water, it produces a wake current which can be turbulent and result in energy wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines water movement. Also, the fins inside the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency of the propulsion system.

Some shipping companies are using self polishing coatings in the hulls of the ships. This, based on maritime experts, helps in avoiding marine organisms from latching onto the hull where they create a significant drag. When vessels have the ability to eliminate this drag using the this layer, they are able to additionally make their vessels more efficient. There are many efforts to improve a ship's effectiveness, including complex engineering methods to easy things such as changing lights. As an example, ships can save power and start to become more environmentally friendly by changing conventional incandescent light bulbs with Light-emitting Diode lights, which eat much less electricity and last for decades.

A few shipping companies like Cosco Casablanca are making significant investments within the development of new fleets that run on liquified propane (LNG), which is the absolute most advanced level and fuel-efficient option available. These ships have slow-speed tri-fuel engines that run on compressed boil-off fuel from the cargo tanks as fuel. During transport, the LNG changes its state to gas because of small heat increases, which causes boil-off to happen. To produce these vessels even more environmentally friendly, they are fitted with an advanced level exhaust recirculation system that significantly reduces nitrogen oxide emissions. Also, the ships are equipped with a gasoline combustion system that lowers the potential of releasing methane into the environment.
