French LNG containment giant GTT and Finnish ship designer Deltamarin have received basic design approval from classification society DNV for a new LNG-powered PCTC.
The approval in principle is for a dual-fuel pure car and truck carrier (PCTC) design, able to carry 8000 CEU, according to a GTT statement issued on Wednesday.
Knut Ørbeck-Nilssen, CEO of DNV Maritime, presented the AiP to GTT’s CEO Philippe Berterottière, and Kristian Knaapi, sales manager at Deltamarin, at the classification society’s headquarters in Oslo this week.
This design introduces a “new generation” of PCTCs, incorporating GTT’s Mark III membrane LNG fuel tank and Deltamarin’s expertise, GTT said.
Moreover, the AiP from DNV confirms that the design of the LNG-fueled PCTC is feasible and that no obstacles exist to prevent the concept from being constructed and operated, GTT said.
GTT and Deltamarin have designed the “most compact” LNG system in order to optimize cargo capacity and energy consumption while providing maximal vessel LNG autonomy.
The 2 bar gauge (barg) design pressure of the LNG fuel tank enables improved pressure holding capabilities and increased operational flexibility especially during bunkering operations, GTT said.
“Following our references in LNG-fueled container vessels and cruise vessels, we are eager to meet the LNG-fueled PCTC challenges with our fit-for-purpose membrane tank solution,” Berterottière said.
Last week, GTT said it has received basic design approval from Japanese classification society, ClassNK, for a new solution applicable to LNG-fueled PCTCs and cruise ships.
This innovation is an upgrade of the Mark III system with a design pressure up to 2 barg for LNG fuel applications, the firm said.
