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

An important task nowadays for the global shipping industry is to reduce its environmental footprint, an attempt that will require a multipronged approach. But this really is no simple task. According to experts, marine engines are complex to alter, and even if engineers can change them in a manner that is likely to 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 awesome changes and striving to find solutions that reduce carbon dioxide emissions. And they are gradually placing those modifications to the test on their fleets of vessels. They truly are increasingly meeting the benchmark requirements of the energy efficiency design index. Certainly, businesses like Morocco Maersk are creating effectiveness in the commercial delivery sector. A great example of technological progress can be seen in the enhancement of the Mewis duct. This is a cylindrical channel which includes incorporated fins, that is situated in the front of the propeller. As the a ship moves through the water, it produces a wake current which can be turbulent and result in power wastage. Nonetheless, 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, that leads to increased energy efficiency for the propulsion system.

Some shipping companies are using self polishing coatings on the hulls of the vessels. This, according to maritime experts, helps in avoiding marine organisms from clinging onto the hull where they cause a significant drag. When vessels are able to eradicate this drag using the coating, they are able to also help make their vessels better. There are various efforts to boost a ship's efficiency, ranging from complex engineering methods to easy things like changing lights. For example, ships can conserve energy and start to become more environmentally friendly by changing traditional incandescent LED lights with LED lights, which eat less electricity and last for many years.

A few shipping companies like Cosco Casablanca are currently making significant investments within the growth of new fleets that operate on liquified propane (LNG), which can be the most advanced level and fuel-efficient option available. These ships have slow-speed tri-fuel engines that run on compressed boil-off fuel from the cargo tanks as fuel. During transport, the LNG changes its state to fuel because of small heat rises, which in turn causes boil-off that occurs. To produce these vessels even more environmentally friendly, they are equipped having an advanced exhaust recirculation system that notably decreases nitrogen oxide emissions. Additionally, the ships include a fuel combustion system that minimises the potential of emitting methane in to the environment.
