At a ceremony held during a seminar in Tokyo, ClassNK issued four Approvals in Principle (AiPs) to GTT, following the latter’s latest development projects in alternative fuels.
These were -
• A 12,500 cu m LNG dual-fuelled VLCC concept fitted with Mark III Flex system.
• An LNG fuel tanks concept with NH3 ready notation that includes material compatibility with NH3, risk assessment and boil-off gas management.
• An 8,000 CEU PCTC LNG dual-fuelled concept with NH3 ready notation.
• GTT’s patented Recycool system applied to LNG fuelled vessels, which is designed to allow the reliquefaction of LNG evaporation in order to reduce greenhouse gas emissions and economic losses.
ClassNK carried out the verification 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.
The Recycool AiP marked a world-first or a system of its kind, ClassNK claimed.
Philippe Berterottière, GTT Chairman and CEO, said: “We are very pleased to have received these Approvals in Principle in person and to be back in Japan after the global pandemic.
“These certifications confirm the research and innovation work performed by GTT engineers and technicians. We thank ClassNK for their trust in our technologies on alternative fuels,” he said.
Masaki Matsunaga, ClassNK Corporate Officer/Director of Plan Approval and Technical Solution Division, said: “It is a great honour to welcome GTT’s team back to Japan and hand over four AiPs for their innovative and inspiring concepts pursuing low and zero carbon shipping upon our rigorous verification process in line with the appropriate standards for each solution.
“We congratulate GTT on achieving these milestones and look forward to continuing our partnership with them in implementing sustainable energy initiatives,” he said.
GTT has also revealed that it has joined the United Nations (UN) Global Compact, the world’s largest corporate sustainability initiative.
The UN Global Compact is a call to companies around the world to align their operations and strategies with the ‘Ten principles’, which derive from the UN’s fundamental texts in the fields of human rights, labour law, the environment and the fight against corruption.
