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

Some shipping companies are utilising self polishing coatings in the hulls of their vessels. This, in accordance with maritime experts, aids in preventing marine organisms from clinging onto the hull where they create a significant drag. So when ships have the ability to eradicate this drag by using the this layer, they are able to also help to make their vessels more efficient. There are many efforts to enhance a ship's efficiency, including complex engineering solutions to simple such things as changing lights. For instance, vessels can conserve energy and start to become more environmentally friendly by replacing old-fashioned incandescent light bulbs with LED lights, which eat less electricity and endure for decades.

An important task these days for the global shipping industry is to reduce its environmental footprint, an attempt that will require a multipronged approach. But this might be no effortless task. Based on specialists, marine engines are complex to change, and even if engineers can change them in a fashion that is likely to make them emit less CO2, altering delivery fleets could be quite expensive. Hence, progress is slow in this domain. However, a range shipping companies like DP World Russia, are making awesome changes and striving to get 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 needs of the energy efficiency design index. Certainly, businesses like Morocco Maersk are creating effectiveness in the commercial delivery sector. A fantastic case of technical progress can be seen in the improvement of the Mewis duct. This is a cylindrical channel that has integrated fins, which is situated 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 power wastage. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines water movement. Also, the fins within the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency for the propulsion system.

A few shipping companies like Cosco Casablanca are making significant investments within the growth of new fleets that operate on liquified gas (LNG), which can be probably the most advanced level and fuel-efficient remedy available. These ships are equipped with 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 because of small temperature rises, which causes boil-off to occur. To make these vessels much more environmentally friendly, they have been equipped by having an advanced level exhaust recirculation system that considerably reduces nitrogen oxide emissions. Additionally, the vessels have a gasoline combustion system that lowers the potential of releasing methane in to the environment.
