GTT (Gaztransport & Technigaz) has signed a cooperation agreement with the South Korean Shipbuilder Hyundai Heavy Industries (HHI) for the industrialization of GTT’s new Mark V technology.
 
A similar partnership was signed a few weeks ago between GTT and Samsung Heavy Industries.
 
The agreement includes the development and qualification of an innovative welding robot for the primary stainless steel and secondary invar membranes. The robot will permit the optimization of the welding process and a reduction in construction time.
 
After some years of research and development, the Mark V technology is an optimized version of the Mark III system and its sister Mark III Flex. As with the Mark III and Mark III Flex, the Mark V technology is composed of a double insulation with reinforced polyurethane foam. The new system also includes an innovative nickel-steel alloy corrugated secondary membrane and offers significant improvement of the warranted daily boil off rate. The Mark V technology has received AIPs (Approval in Principal) from major classification societies.
 
“We are very pleased to see HHI embarked onto this major development program,” said Philippe Berterottière, Chairman and CEO of GTT. “It allows us to be quite confident in the possibility for Mark V to be commercialized from 2015.”
