Introducing technologies such as the Mewis duct prove significant strides in optimising propulsion systems for greater energy efficiency.

Some shipping companies are using self polishing coatings in the hulls of the ships. This, according to maritime experts, helps in avoiding marine organisms from clinging on the hull where they result in a significant drag. So when vessels have the ability to eliminate this drag by using the coating, they are able to additionally help make their ships more effective. There are many efforts to improve a ship's efficiency, including complex engineering methods to simple things like changing lights. For example, ships can save power and start to become more environmentally friendly by replacing traditional incandescent LED lights with Light-emitting Diode lights, which consume less electricity and endure for many years.

Several shipping companies like Cosco Casablanca are making significant investments in the growth of new fleets that operate on liquified gas (LNG), which is the absolute most advanced 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 transport, the LNG changes its state to gas as a result of slight heat increases, which causes boil-off that occurs. To produce these ships more environmentally friendly, they are equipped by having an advanced exhaust recirculation system that notably reduces nitrogen oxide emissions. Furthermore, the ships have a gasoline combustion system that minimises the potentiality of releasing methane to the atmosphere.

An essential task nowadays for the global shipping industry is to reduce its environmental impact, an effort that will require a multipronged approach. But this really is no easy task. In accordance with experts, marine engines are complicated to change, and even if designers can modify them in a manner that is likely to make them produce less CO2, changing delivery fleets would be very costly. Thus, progress is slow in this domain. Nonetheless, a number of shipping companies like DP World Russia, are making outstanding changes and striving to make solutions that reduce co2 emissions. Plus they are gradually placing those modifications to work on their fleets of vessels. They are increasingly meeting the benchmark demands of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating efficiency in the commercial delivery sector. A fantastic example of technical progress is seen in the enhancement of the Mewis duct. This is a cylindrical channel which includes integrated fins, that 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 power wastage. Nevertheless, the Mewis duct directs this wake current towards the propeller and streamlines 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.
