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

An essential task nowadays for the global shipping industry is to reduce its ecological footprint, an attempt that requires a multipronged approach. But this might be no simple task. Based on specialists, marine engines are complex to improve, and even if engineers can alter them in a way that will make them produce less CO2, modifying shipping fleets could be pricey. Hence, progress is sluggish in this domain. Nonetheless, a number of shipping companies like DP World Russia, are making amazing modifications and striving to find solutions that decrease co2 emissions. And they are gradually placing those changes to work on their fleets of vessels. They are increasingly meeting the benchmark demands of the energy efficiency design index. Certainly, companies like Morocco Maersk are driving effectiveness in the commercial delivery sector. An excellent example of technical progress is seen in the improvement of the Mewis duct. This is a cylindrical channel which includes integrated fins, that is located in the front of the propeller. As the a ship moves through water, it creates a wake current that can be turbulent and result in energy wastage. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines water movement. Furthermore, the fins inside 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 utilising self polishing coatings in the hulls of the vessels. This, according to maritime experts, aids in preventing marine organisms from attaching on the hull where they produce a significant drag. When vessels have the ability to eradicate this drag by using the coating, they can also help to make their ships better. There are many efforts to boost a ship's effectiveness, including complex engineering methods to easy things such as changing lights. As an example, vessels can conserve energy and start to become more environmentally friendly by replacing traditional incandescent light bulbs with LED lights, which consume less electricity and endure for many years.

A few shipping companies like Cosco Casablanca are making significant investments within the development of new fleets that run on liquified natural gas (LNG), which is the most higher level and fuel-efficient option available. These vessels include slow-speed tri-fuel engines that run on compressed boil-off fuel through the cargo tanks as fuel. During transportation, the LNG changes its state to fuel as a result of slight temperature increases, which in turn causes boil-off to happen. To create these ships much more environmentally friendly, they have been fitted having an advanced level exhaust recirculation system that dramatically reduces nitrogen oxide emissions. Furthermore, the vessels are equipped with a fuel combustion system that lowers the potential of emitting methane to the atmosphere.
