French LNG containment giant GTT has secured approvals in principle from classification society DNV for two LNG-powered vessel designs and a new tank concept.
GTT said in a statement issued on Thursday that it developed the two concepts for LNG-powered vessels with the support of the Finnish ship designer Deltamarin.
Last year, the two firms also received OK from DNV for a new LNG-powered PCTC.
DNV now approved a concept for an LNG dual-fuel Suezmax tanker fitted with a fuel tank of 5,500 cbm equipped with GTT’s Mark III system.
Also, the classification society granted AiP to a concept for an LNG dual-fuel very large crude carrier (VLCC) fitted with a fuel tank of 12,500 cbm equipped with GTT’s Mark III system.
GTT said these tanker concepts aim at maximizing vessel autonomy thanks to a large tank, giving shipowners and charterers the benefit of longer trade navigation with only one refueling operation, with no impact on cargo capacity.
Besides these two concepts, GTT won AiP for a concept for a Mark III LNG fuel tank with ammonia-ready notation that includes material compatibility with ammonia, risk assessment and boil-off gas management.
Based on an extensive compatibility tests campaign carried out by GTT, the NH3-rady concept paves the way for potential conversion of the fuel tank to ammonia in the future, offering additional flexibility to comply with the environmental regulations, GTT said.
