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

Several shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run using liquified propane (LNG), that is probably the most higher level and fuel-efficient solution available. These ships include slow-speed tri-fuel engines that run using compressed boil-off fuel from the cargo tanks as fuel. During transport, the LNG changes its state to fuel as a result of slight temperature rises, that causes boil-off that occurs. To make these ships more environmentally friendly, they have been equipped with an advanced exhaust recirculation system that dramatically decreases nitrogen oxide emissions. Furthermore, the vessels are equipped with a gas combustion system that lowers the potential of emitting methane to the environment.

An essential task these days for the global shipping industry is to reduce its environmental footprint, an effort that needs a multipronged approach. But this is certainly no simple task. In accordance with experts, marine engines are complex to change, and even if engineers can modify them in a way that makes them produce less CO2, altering delivery fleets is pricey. Thus, progress is sluggish in this domain. Nonetheless, a range shipping companies like DP World Russia, are making impressive changes and striving to find solutions that decrease co2 emissions. Plus they are slowly placing those modifications to the test on their fleets of vessels. These are typically increasingly fulfilling the benchmark needs of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving efficiency in the commercial shipping sector. An excellent example of technical progress is seen into the enhancement of the Mewis duct. This is a cylindrical channel which has incorporated fins, that is situated 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 water flow. Moreover, the fins inside 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 utilising self polishing coatings in the hulls of their ships. This, according to maritime professionals, helps in avoiding marine organisms from clinging on the hull where they result in a significant drag. So when vessels have the ability to eradicate this drag using the coating, they are able to additionally help to make their ships more efficient. There are many different efforts to boost a ship's effectiveness, which range from complex engineering solutions to easy such things as changing bulbs. For instance, vessels can conserve energy and start to become more environmentally friendly by replacing old-fashioned incandescent LED lights with LED lights, which consume less electricity and endure for decades.
