GTT (Gaztransport & Technigaz) has received approval from Bureau Veritas (BV) for its membrane containment systems and liquefied natural gas (LNG) technology applications.

The Mark III Flex+ containment system and GTT MARS containment system, both developed for liquefied petroleum (LPG) carriers, have received approval in principle (AiP) from BV.

The AiPs have been given for a 6,500 cbm bunker barge (jointly developed between DSEC and GTT) and for the design of an 180,000 cbm LNG carrier, which is being finalised.

An additional AiP has been granted for a solution for vapour pocket management allowing LNG carriers, in compliance with the revised IGC Code, to operate with an increased filling limit (above 98%). GTT has also received an AiP for its NO96  pressurisation system evolution to provide enhanced maintenance flexibility and safety, and reduced cooling down features of both the NO96 and Mark III systems to improve cargo operations.

Matthieu de Tugny, COO, Bureau Veritas Marine & Offshore said: “These approvals are helping GTT expand the range and depth of their technologies. The increasing sophistication of containment systems and expansion of their application – as in CMA CGM’s breakthrough order for large containerships with membrane tanks – is driving the adoption and development of gas transportation and LNG as a marine fuel as well supporting the marine gas trades.’

Philippe Berterottière, Chairman and CEO, GTT added: “We are very pleased to be granted these approvals by Bureau Veritas with whom GTT has a very close partnership for decades. We have demonstrated the reliability of our latest developments and their ability to meet the owners’ requirements.  I believe these new systems and designs will help the shipping industry to move forward and reduce the ecological footprint.’
