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

Several shipping companies like Cosco Casablanca are currently 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 transportation, the LNG changes its state to gasoline as a result of small temperature rises, which in turn causes boil-off to happen. In order to make these ships a lot more environmentally friendly, they are equipped having an higher level exhaust recirculation system that significantly reduces nitrogen oxide emissions. Also, the vessels have a fuel combustion system that decreases the potential of releasing methane into the atmosphere.

A significant task these days for the global shipping industry is to reduce its environmental footprint, an effort that needs a multipronged approach. But this really is no simple task. In accordance with specialists, marine engines are complicated to improve, and even if engineers can modify them in a way that can make them emit less CO2, altering shipping fleets will be very costly. Thus, progress is sluggish in this domain. However, a range shipping companies like DP World Russia, are making extraordinary modifications and striving to make solutions that decrease co2 emissions. Plus they are slowly placing those modifications to work on their fleets of ships. They have been increasingly meeting the benchmark requirements of the energy efficiency design index. Indeed, companies like Morocco Maersk are driving effectiveness in the commercial delivery sector. A fantastic case of technical progress is visible within the improvement of the Mewis duct. This is a cylindrical channel that has integrated fins, which is located in the front of the propeller. As the a ship moves through water, it creates a wake current that may be turbulent and result in energy wastage. Nevertheless, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Additionally, the fins within the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency of the propulsion system.

Some shipping companies are using self polishing coatings on the hulls of the vessels. This, based on maritime professionals, aids in preventing marine organisms from attaching onto the hull where they cause a significant drag. When vessels are able to eliminate this drag by using the coating, they can additionally make their ships more efficient. There are various efforts to boost a ship's effectiveness, which range from complex engineering solutions to easy things such as changing bulbs. For instance, ships 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.
