GTT’s alternative fuel projects obtain approval from ClassNK

ClassNK has issued four Approvals in Principle (AiPs) for GTT’s following latest development projects in alternative fuels.

The four alternative fuel development projects include – Concept of 12,500m3 LNG Dual-fuelled VLCC fitted with Mark III Flex system, Concept of LNG Fuel Tanks with NH3 ready notation that includes material compatibility with NH3, risk assessment and Boil-off gas management, Concept of 8,000 CEU PCTC LNG Dual-fuelled with NH3 ready notation, and Recycool™ system applied to LNG fuelled vessels which is designed for allowing the reliquefaction of LNG evaporation in order to reduce greenhouse gas emissions and economic losses.

ClassNK carried out the verification on those accomplishments in line with its rules including Part N incorporating the IGC Code, Part GF incorporating the IGF Code, and its Guidelines for Ships Using Alternative Fuels. Among the above, the AiP for Recycool™ marked a world-first AiP for a system of its kind.
