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

Some shipping companies are utilising self polishing coatings on the hulls of their vessels. This, according to maritime specialists, helps in avoiding marine organisms from latching onto the hull where they produce a significant drag. So when ships are able to eradicate this drag utilising the coating, they could additionally make their ships more efficient. There are many efforts to boost a ship's efficiency, ranging from complex engineering answers to easy things such as changing lights. For instance, ships can save energy and start to become more environmentally friendly by replacing conventional incandescent LED lights with Light-emitting Diode lights, which eat much less electricity and endure for many years.

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

An essential task nowadays for the global shipping industry would be to reduce its ecological impact, an effort that will require a multipronged approach. But this will be no simple task. Based on experts, marine engines are complicated to change, and even if designers can change them in a fashion that can certainly 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 impressive modifications and striving to make solutions that reduce co2 emissions. And they are slowly placing those changes to the test on their fleets of vessels. They have been increasingly fulfilling the benchmark requirements of the energy efficiency design index. Certainly, businesses like Morocco Maersk are driving effectiveness in the commercial delivery sector. An excellent example of technical progress can be seen within the enhancement of the Mewis duct. This is a cylindrical channel that has integrated fins, that will be located in the front of the propeller. As the a ship moves through the 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 flow. Additionally, the fins inside the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency of the propulsion system.
