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

A few shipping companies like Cosco Casablanca are making significant investments within the development of new fleets that run on liquified gas (LNG), that will be the most advanced level and fuel-efficient remedy 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 transport, the LNG changes its state to gas because of small heat increases, which causes boil-off to occur. To produce these vessels much more environmentally friendly, they are fitted with an advanced level exhaust recirculation system that notably decreases nitrogen oxide emissions. Additionally, the ships are equipped with a gasoline combustion system that lowers the potentiality of emitting methane in to the atmosphere.

An important task nowadays for the global shipping industry would be to reduce its ecological impact, an attempt that will require a multipronged approach. But this will be no easy task. According to experts, marine engines are complex to change, and even if engineers can change them in a manner that makes them produce less CO2, modifying delivery fleets is pricey. Thus, progress is sluggish in this domain. Nonetheless, a range shipping companies like DP World Russia, are making impressive changes and striving to find solutions that decrease co2 emissions. Plus they are slowly placing those modifications to the test on their fleets of vessels. These are typically increasingly meeting the benchmark needs of the energy efficiency design index. Indeed, companies like Morocco Maersk are driving efficiency in the commercial delivery sector. A fantastic case of technical progress is visible within 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 the water, it creates 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 the water flow. Furthermore, the fins inside the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency for the propulsion system.

Some shipping companies are utilising self polishing coatings on the hulls of their ships. This, in accordance with maritime professionals, helps in avoiding marine organisms from attaching onto the hull where they cause a significant drag. When vessels have the ability to eliminate this drag by using the coating, they are able to additionally help to make their ships more effective. There are many different efforts to improve a ship's efficiency, ranging from complex engineering methods to easy such things as changing light bulbs. As an example, vessels can save energy and start to become more environmentally friendly by changing conventional incandescent light bulbs with Light-emitting Diode lights, which eat much less electricity and last for decades.
