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

A significant task these days for the global shipping industry is to reduce its ecological impact, an effort that needs a multipronged approach. But that is no simple task. According to experts, marine engines are complicated to change, and even if engineers can alter them in a way that could make them emit less CO2, altering delivery fleets would be very costly. Thus, progress is sluggish in this domain. Nevertheless, a number of shipping companies like DP World Russia, are making awesome changes and striving to make solutions that reduce carbon dioxide emissions. And they are slowly placing those changes to work on their fleets of vessels. They truly are increasingly meeting the benchmark requirements of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating efficiency in the commercial shipping sector. A great case of technical progress can be seen in the improvement of the Mewis duct. This is a cylindrical channel which has incorporated fins, that will be situated 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. But, the Mewis duct directs this wake current towards the propeller and streamlines the water flow. Moreover, the fins in the duct twist the current before it reaches the propeller blades, that leads to increased energy efficiency for the propulsion system.

Some shipping companies are utilising self polishing coatings in the hulls of their ships. This, according to maritime specialists, aids in preventing marine organisms from clinging on the hull where they produce a significant drag. So when ships are able to eliminate this drag by using the coating, they could also help to make their vessels better. There are many different efforts to improve a ship's effectiveness, which range from complex engineering answers to easy things such as changing lights. As an example, vessels can conserve power and start to become more environmentally friendly by changing old-fashioned incandescent LED lights with Light-emitting Diode lights, which eat much less electricity and last for decades.

Several shipping companies like Cosco Casablanca are currently making significant investments in the development of new fleets that operate on liquified gas (LNG), which can be 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 fuel. During transportation, the LNG changes its state to gas due to small heat increases, that causes boil-off that occurs. To help make these vessels more environmentally friendly, they are fitted with an advanced exhaust recirculation system that significantly decreases nitrogen oxide emissions. Furthermore, the vessels include a gasoline combustion system that minimises the potential of emitting methane in to the environment.
