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

An important task these days for the global shipping industry is to reduce its ecological impact, an effort that requires a multipronged approach. But this really is no effortless task. According to experts, marine engines are complicated to alter, and even if engineers can modify them in a fashion that will make them produce less CO2, altering shipping fleets would be pricey. Thus, progress is slow in this domain. Nevertheless, a range shipping companies like DP World Russia, are making awesome modifications and striving to get solutions that reduce co2 emissions. And they are gradually placing those changes to the test on their fleets of ships. They have been increasingly fulfilling the benchmark needs of the energy efficiency design index. Indeed, businesses like Morocco Maersk are driving effectiveness in the commercial shipping sector. An excellent case of technological progress is seen in the enhancement of the Mewis duct. This is a cylindrical channel which has integrated fins, that is situated in the front of the propeller. As the a ship moves through water, it produces a wake current that may be turbulent and result in energy wastage. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Furthermore, the fins within the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency for the propulsion system.

Some shipping companies are using self polishing coatings in the hulls of their ships. This, in accordance with maritime specialists, helps in avoiding marine organisms from attaching on the hull where they result in a significant drag. When ships are able to eradicate this drag by using the this layer, they are able to also make their ships better. There are various efforts to improve a ship's effectiveness, ranging from complex engineering answers to easy things like changing bulbs. As an example, ships can save power and start to become more environmentally friendly by changing traditional incandescent light bulbs with Light-emitting Diode lights, which consume less electricity and last for many years.

A few shipping companies like Cosco Casablanca are currently making significant investments within the growth of new fleets that run on liquified gas (LNG), that will be the most advanced level and fuel-efficient remedy available. These vessels have slow-speed tri-fuel engines that run on compressed boil-off gas from the cargo tanks as fuel. During transport, the LNG changes its state to fuel as a result of slight temperature rises, which in turn causes boil-off to happen. In order to make these ships even more environmentally friendly, they are fitted by having an advanced level exhaust recirculation system that somewhat decreases nitrogen oxide emissions. Additionally, the ships are equipped with a gas combustion system that lowers the potential of releasing methane to the atmosphere.
