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

A significant task nowadays for the global shipping industry would be to reduce its environmental footprint, an effort that will require a multipronged approach. But this is no easy task. According to specialists, marine engines are complicated to alter, and even if designers can change them in a way that can make them emit less CO2, changing shipping fleets could be pricey. Thus, progress is slow in this domain. However, a number of shipping companies like DP World Russia, are making significant changes and striving to make solutions that decrease co2 emissions. And they are gradually placing those modifications to work on their fleets of ships. They are increasingly fulfilling the benchmark needs of the energy efficiency design index. Indeed, companies like Morocco Maersk are creating effectiveness in the commercial shipping sector. An excellent example of technical progress is seen within the improvement 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 water, it produces a wake current that can be turbulent and result in power wastage. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines the water flow. Additionally, the fins in 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 currently making significant investments within the development of new fleets that run on liquified propane (LNG), which can be the most higher level and fuel-efficient remedy available. These ships have slow-speed tri-fuel engines that run on compressed boil-off fuel through the cargo tanks as fuel. During transport, the LNG changes its state to gasoline due to small temperature increases, which in turn causes boil-off to occur. To help make these ships much more environmentally friendly, they have been fitted having an advanced exhaust recirculation system that somewhat decreases nitrogen oxide emissions. Additionally, the vessels include a fuel combustion system that lowers the potential of emitting methane into the environment.

Some shipping companies are using self polishing coatings in the hulls of their vessels. This, according to maritime specialists, helps prevent marine organisms from clinging onto the hull where they create a significant drag. So when vessels are able to eradicate this drag by using the coating, they are able to also make their ships more effective. There are numerous efforts to boost a ship's efficiency, including complex engineering solutions to easy things like changing bulbs. As an example, ships can conserve energy and start to become more environmentally friendly by replacing old-fashioned incandescent light bulbs with Light-emitting Diode lights, which consume less electricity and last for many years.
