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

An important task these days for the global shipping industry is to reduce its ecological footprint, an attempt that will require a multipronged approach. But this will be no simple task. Based on experts, marine engines are complicated to alter, and even if engineers can alter them in a manner that can make them emit less CO2, modifying shipping fleets would be pricey. Hence, progress is sluggish in this domain. However, a number of shipping companies like DP World Russia, are making amazing modifications and striving to get solutions that reduce co2 emissions. And they are slowly putting those modifications to work on their fleets of vessels. They have been increasingly fulfilling the benchmark needs of the energy efficiency design index. Certainly, companies like Morocco Maersk are creating efficiency in the commercial delivery sector. A great case of technological progress is seen in the enhancement of the Mewis duct. This is a cylindrical channel that has incorporated fins, which is 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 energy wastage. But, 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 of the propulsion system.

Some shipping companies are utilising self polishing coatings on the hulls of their vessels. This, according to maritime specialists, helps in avoiding marine organisms from latching on the hull where they cause a significant drag. So when vessels have the ability to eliminate this drag using the this layer, they can also make their ships better. There are many different efforts to enhance a ship's efficiency, including complex engineering solutions to simple such things as changing lights. For instance, ships can save power and start to become more environmentally friendly by changing traditional incandescent light bulbs with Light-emitting Diode lights, which eat much less electricity and last for decades.

Several shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run on liquified gas (LNG), that will be the most advanced and fuel-efficient remedy available. These ships include slow-speed tri-fuel engines that run using compressed boil-off fuel through the cargo tanks as gas. During transport, the LNG changes its state to gas due to slight temperature rises, which in turn causes boil-off to happen. To help make these vessels much more environmentally friendly, they have been equipped having an advanced exhaust recirculation system that considerably reduces nitrogen oxide emissions. Additionally, the ships are equipped with a gas combustion system that minimises the potential of releasing methane into the atmosphere.
