As an alternative to small additional devices, shipowners are considering retrofitting revolutionary and innovative concepts albeit at a more meaningful cost, such as air lubrication systems that reduce frictional resistance. Frictional resistance is the dominant feature of slow-speed vessels. Hence, by…
ESDs provide a direct increase in vessel propulsion efficiency by reducing hull resistance and improving propeller thrust. In particular they comprise devices fitted before or after the propeller, while also having high-performance hull coatings to reduce resistance. In front of…
Along with EEDI, the IMO introduced the Ship energy efficiency management plan (SEEMP). It is the complementary measure that establishes a mechanism to improve the energy efficiency of a ship in a cost-effective manner. SEEMP includes the enhancement of the…
During the MEPC 62 (July 2011), the IMO adopted the Energy efficiency design index for new ships which establishes an energy efficiency identity for all the new-built ships since 2013. The IMO utilises a specific formula that estimates the CO2…
Is an operational measure of how efficiently a vessel transports its cargo, essentially in grams of Co2 emitted by (i) cargo-carrying capacity and (ii) nautical mile. The CII calculation is essentially more straightforward, albeit more complex when it comes to…
The EEXI provides a framework for determining the efficiency of the design of a vessel by expressing its energy efficiency / emissions performance. EEXI regulation relates to existing ships, but each ship type has different factors to consider (the strictest…
The importance of these metrics relates to: The ENVIRONMENTAL side, because there are increasingly stringent requirements related to emissions from ships The SOCIAL point of view, for the areas of crew well-being, as well as health and safety on board,…
"Did you know that ESG is the key term when it comes to future-proof corporate governance. Environmental, social, and governance (ESG) criteria are used to screen investments based on corporate policies and to encourage companies to act responsibly, monitor how…
