Some shipping companies are meeting and surpassing the benchmarks set by the efficiency designs indexes. Find more.

Some shipping companies are utilising self polishing coatings on the hulls of their ships. This, according to maritime specialists, helps in avoiding marine organisms from clinging on the hull where they cause a significant drag. So when ships are able to eliminate this drag by using the this layer, they could additionally help to make their vessels better. There are many different 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 Light-emitting Diode lights, which eat much less electricity and endure for many years.

A significant task nowadays for the global shipping industry would be to reduce its environmental footprint, an attempt that requires a multipronged approach. But this might be no easy task. According to specialists, marine engines are complicated to change, and even if engineers can alter them in a manner that could make them produce less CO2, changing delivery fleets could be very costly. Hence, progress is sluggish in this domain. However, a number of shipping companies like DP World Russia, are making remarkable changes and striving to make solutions that reduce carbon dioxide emissions. Plus they are gradually placing those changes to the test on their fleets of vessels. They have been increasingly meeting the benchmark demands of the energy efficiency design index. Indeed, businesses like Morocco Maersk are creating efficiency in the commercial delivery sector. An excellent case of technological 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 energy wastage. However, the Mewis duct directs this wake current towards the propeller and streamlines the water movement. Moreover, the fins within the duct twist the current before it reaches the propeller blades, which leads to increased energy efficiency for the propulsion system.

A few shipping companies like Cosco Casablanca are making significant investments in the development of new fleets that run on liquified gas (LNG), which is probably the most higher level and fuel-efficient solution available. These ships have slow-speed tri-fuel engines that run using compressed boil-off gas from the cargo tanks as gas. During transport, the LNG changes its state to gas because of small heat increases, which causes boil-off to happen. In order to make these ships a lot more environmentally friendly, they are equipped having an higher level exhaust recirculation system that considerably reduces nitrogen oxide emissions. Also, the vessels have a fuel combustion system that minimises the potential of emitting methane to the environment.
