Integrating advanced exhaust recirculation systems is considerably reducing nitrogen oxide emissions.

Some shipping companies are using self polishing coatings in the hulls of the ships. This, based on maritime professionals, helps prevent marine organisms from attaching on the hull where they produce a significant drag. So when ships have the ability to eradicate this drag utilising the coating, they could additionally make their ships more efficient. There are many efforts to boost a ship's effectiveness, ranging from complex engineering solutions to simple things such as changing lights. For instance, ships can save energy and start to become more environmentally friendly by replacing conventional incandescent LED lights with Light-emitting Diode lights, which eat much less electricity and endure for many years.

Several shipping companies like Cosco Casablanca are currently making significant investments in the development of new fleets that operate on liquified propane (LNG), that will be the most advanced and fuel-efficient solution available. These ships are equipped with 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 slight heat increases, that causes boil-off that occurs. To make these vessels much more environmentally friendly, they have been equipped having an higher level exhaust recirculation system that notably decreases nitrogen oxide emissions. Also, the ships include a gas combustion system that minimises the potential of emitting methane in to the environment.

A significant task nowadays for the global shipping industry is to reduce its environmental impact, an attempt that needs a multipronged approach. But that is no effortless task. According to specialists, marine engines are complicated to alter, and even if engineers can alter them in a fashion that could make them emit less CO2, changing delivery fleets is very costly. Hence, progress is sluggish in this domain. However, a number of shipping companies like DP World Russia, are making significant modifications and striving to get solutions that reduce co2 emissions. Plus they are gradually placing those changes to the test on their fleets of vessels. They are increasingly fulfilling the benchmark needs of the energy efficiency design index. Indeed, businesses like Morocco Maersk are driving effectiveness in the commercial shipping sector. A fantastic example of technical progress is visible in the enhancement of the Mewis duct. This is a cylindrical channel that has incorporated fins, which is located in the front of the propeller. As the a ship moves through the water, it creates a wake current that can be turbulent and result in power wastage. Nevertheless, the Mewis duct directs this wake current towards the propeller and streamlines water flow. Additionally, the fins inside the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency of the propulsion system.
