(ansa)Genova – Italian classification society RINA has granted approval-in-principle (AiP) for a 50,000-ton ammonia-fueled oil/chemical tanker developed and designed by Shanghai Shipyard, a subsidiary of China State Shipbuilding Corporation (CSSC).
The professional teams of Shanghai Shipyard and RINA have carried out extensive and in-depth analysis of the ammonia-powered tanker design. The company expects that the application of ammonia fuel will give MR tanker design significant advantages in dealing with CO2 reduction and greenhouse gas (GHG) regulations.
When using ammonia fuel as the main fuel, the ship’s energy efficiency design index (EEDI) of this type will be reduced by more than 90% compared with the conventional design. Furthermore, the low-carbon characteristics of ship are expected to effectively meet the International Maritime Organisation’s (IMO) existing ship energy efficiency index (EEXI) and carbon emission intensity Index (CII) requirements to address challenges such as carbon tax or carbon trading regulations in the future: “It is understood that since ammonia fuel itself contains no carbon at all, it can also perfectly solve the IMO medium- and long-term carbon reduction goals technically. Therefore, ammonia fuel has been more and more respected by the shipping market as an alternative zero-carbon fuel,” according to the firm managed by Ugo Salerno.
