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

An essential task nowadays for the global shipping industry is always to reduce its ecological footprint, an effort that needs a multipronged approach. But this really is no easy task. According to experts, marine engines are complicated to improve, and even if designers can modify them in a manner that will make them emit less CO2, altering delivery fleets could be quite expensive. Hence, progress is slow in this domain. Nevertheless, a number of shipping companies like DP World Russia, are making amazing modifications and striving to get solutions that reduce carbon dioxide emissions. And they are gradually putting those changes to work on their fleets of vessels. They are increasingly meeting the benchmark requirements of the energy efficiency design index. Certainly, businesses like Morocco Maersk are creating effectiveness in the commercial shipping sector. A great example of technical progress is seen into the enhancement of the Mewis duct. This is a cylindrical channel which has integrated fins, which is located in the front of the propeller. As the a ship moves through water, it produces a wake current that can be turbulent and result in power wastage. But, the Mewis duct directs this wake current towards the propeller and streamlines water flow. Furthermore, the fins within the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency of the propulsion system.

Some shipping companies are using self polishing coatings in the hulls of their vessels. This, based on maritime experts, helps prevent marine organisms from clinging onto the hull where they cause a significant drag. When ships have the ability to eliminate this drag utilising the coating, they can additionally help make their vessels more efficient. There are many different efforts to improve a ship's efficiency, which range from complex engineering solutions to easy things like changing bulbs. For instance, ships can conserve energy and start to become more environmentally friendly by replacing old-fashioned incandescent light bulbs with Light-emitting Diode lights, which consume less electricity and last for many years.

Several shipping companies like Cosco Casablanca are currently making significant investments in the growth of new fleets that run using liquified natural gas (LNG), that will be the most advanced level and fuel-efficient option available. These vessels are equipped with slow-speed tri-fuel engines that run on compressed boil-off gasoline through the cargo tanks as gas. During transportation, the LNG changes its state to gas because of small heat increases, which causes boil-off to occur. To help make these vessels even more environmentally friendly, they are fitted by having an advanced level exhaust recirculation system that somewhat decreases nitrogen oxide emissions. Furthermore, the vessels are equipped with a gas combustion system that minimises the potential of emitting methane in to the environment.
