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

An essential task these days for the global shipping industry would be to reduce its environmental impact, an effort that will require a multipronged approach. But this is certainly no effortless task. According to specialists, marine engines are complex to improve, and even if engineers can alter them in a manner that is likely to make them produce less CO2, changing delivery fleets will be pricey. Hence, progress is sluggish in this domain. However, a range shipping companies like DP World Russia, are making extraordinary changes and striving to make solutions that reduce co2 emissions. And they are gradually placing those modifications to the test on their fleets of ships. They truly are increasingly meeting the benchmark needs of the energy efficiency design index. Certainly, companies like Morocco Maersk are creating efficiency in the commercial shipping sector. A fantastic example of technological progress is seen in the improvement 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 water, it produces a wake current that may be turbulent and result in power wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Additionally, the fins inside the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency for the propulsion system.

A few shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that operate on liquified gas (LNG), which is the most advanced level and fuel-efficient option available. These vessels have slow-speed tri-fuel engines that run on compressed boil-off gas from the cargo tanks as fuel. During transport, the LNG changes its state to gasoline as a result of small heat increases, which causes boil-off to occur. To produce these vessels more environmentally friendly, they have been equipped having an higher level exhaust recirculation system that significantly reduces nitrogen oxide emissions. Additionally, the ships include a gasoline combustion system that lowers the potentiality of emitting methane to the atmosphere.

Some shipping companies are using self polishing coatings on the hulls of their ships. This, according to maritime experts, helps prevent marine organisms from latching onto the hull where they produce a significant drag. When vessels have the ability to eradicate this drag using the coating, they can also make their vessels more effective. There are many efforts to improve a ship's efficiency, ranging from complex engineering solutions to easy things such as changing lights. As an example, vessels can save power and start to become more environmentally friendly by changing conventional incandescent light bulbs with LED lights, which eat much less electricity and endure for decades.
