Introducing technologies like the Mewis duct display significant strides in optimising propulsion systems for greater energy efficiency.

Some shipping companies are using self polishing coatings on the hulls of their ships. This, based on maritime specialists, helps in avoiding marine organisms from clinging on the hull where they cause a significant drag. So when ships are able to eliminate this drag by using the coating, they can additionally make their vessels more efficient. There are various efforts to boost a ship's effectiveness, which range from complex engineering solutions to easy such things as changing light bulbs. For instance, vessels can save energy and start to become more environmentally friendly by changing conventional incandescent light bulbs with Light-emitting Diode lights, which eat less electricity and last for many years.

A few shipping companies like Cosco Casablanca are currently making significant investments within the development of new fleets that run on liquified propane (LNG), which can be the most higher level and fuel-efficient remedy available. These ships have slow-speed tri-fuel engines that run on compressed boil-off gas through the cargo tanks as fuel. During transport, the LNG changes its state to gasoline due to small temperature increases, which in turn causes boil-off to occur. In order to make these ships even more environmentally friendly, they have been fitted having an advanced level exhaust recirculation system that significantly decreases nitrogen oxide emissions. Additionally, the vessels are equipped with a fuel combustion system that lowers the potentiality of releasing methane in to the atmosphere.

An important task these days for the global shipping industry is to reduce its ecological footprint, an attempt that requires a multipronged approach. But this is certainly no effortless task. In accordance with experts, marine engines are complicated to change, and even if designers can modify them in a fashion that can make them produce less CO2, changing delivery fleets would be very costly. Hence, progress is slow in this domain. Nonetheless, a number of shipping companies like DP World Russia, are making impressive changes and striving to make solutions that reduce co2 emissions. Plus they are gradually placing those changes to work on their fleets of vessels. They are increasingly fulfilling 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 energy wastage. Nevertheless, the Mewis duct directs this wake current towards the propeller and streamlines water movement. Moreover, the fins in the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency of the propulsion system.
