Energy equipment and marine solutions company Hanwha Power Systems, a part of the South Korean Hanwha Group, has received approval in principle (AiP) from the American Bureau of Shipping (ABS) for the ammonia fuel gas turbine conversion design aimed at 174,000 cbm LNG carriers.
As disclosed, the AiP was granted following a review and approval process of essential engineering documents, including the process flow diagram (PFD), operation and control philosophy, as well as equipment list, general arrangement (GA), machinery arrangement (MA), toxic area detection, emergency shutdown system (ESD), fire safety drawings, and the hazard identification (HAZID) report. It reportedly provides Hanwha with a basis to propose retrofit packages for converting various ship types, including existing LNG carriers, to ammonia fuel.
