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

Some shipping companies are using self polishing coatings in the hulls of their ships. This, in accordance with maritime experts, helps in avoiding marine organisms from latching onto the hull where they produce a significant drag. So when ships have the ability to eliminate this drag using the this layer, they can also make their ships better. There are many different efforts to enhance a ship's efficiency, including complex engineering solutions to simple things such as changing lights. For instance, vessels can conserve energy and start to become more environmentally friendly by replacing conventional incandescent LED lights with LED lights, which consume less electricity and endure for many years.

An essential task nowadays for the global shipping industry would be to reduce its ecological impact, an effort that needs a multipronged approach. But this is certainly no easy task. According to experts, marine engines are complicated to improve, and even if designers can modify them in a manner that could make them produce less CO2, changing shipping fleets will be very costly. Thus, progress is sluggish in this domain. Nonetheless, a number of shipping companies like DP World Russia, are making spectacular modifications and striving to make solutions that decrease carbon dioxide emissions. And they are gradually putting those modifications to the test on their fleets of vessels. They truly are increasingly fulfilling the benchmark demands of the energy efficiency design index. Indeed, companies like Morocco Maersk are driving efficiency in the commercial shipping sector. An excellent example of technological progress is visible within the enhancement of the Mewis duct. This is a cylindrical channel which has incorporated fins, that is located in the front of the propeller. As the a ship moves through water, it creates a wake current that may be turbulent and result in power wastage. Nonetheless, the Mewis duct directs this wake current towards the propeller and streamlines water movement. Also, the fins within the duct twist the current before it reaches the propeller blades, leading to increased energy efficiency for the propulsion system.

A few shipping companies like Cosco Casablanca are making significant investments within the development of new fleets that operate on liquified gas (LNG), which can be probably the most advanced level and fuel-efficient solution available. These ships are equipped with slow-speed tri-fuel engines that run on compressed boil-off fuel through the cargo tanks as gas. During transport, the LNG changes its state to gasoline because of slight temperature rises, that causes boil-off that occurs. In order to make these vessels more environmentally friendly, they have been fitted with an advanced exhaust recirculation system that significantly decreases nitrogen oxide emissions. Furthermore, the vessels include a gas combustion system that minimises the potentiality of emitting methane to the atmosphere.
