French engineering company, GTT announced that it has received, at the end of 2017, an order from a South Korean shipyard about the design of the LNG tanks of a new LNG carrier, which is expected to be delivered on the first quarter of 2020.
Namely, GTT will design the LNG tanks of the unit, which will have a capacity of 174,000 m3. The insulation solution Mark III Flex has been chosen for its ability to reduce the daily guaranteed Boil-Off gas rate to 0.085% of tank volume, with 48 vessels in service already benefit from this technology.
Mark III Flex’s primary membrane is made of corrugated stainless steel 304 L, 1.2mm thick. It contains the LNG cargo and is directly supported by and fixed to the insulation system.
The secondary membrane is made of Triplex, a thin sheet of aluminum between two layers of glass cloth and resin. It is positioned inside the prefabricated insulation panels between the two insulation layers.
Furthermore, the insulation consists of a load-bearing system made of prefabricated panels in reinforced polyurethane foam including both primary and secondary insulation layers and the secondary membrane. The total thickness of the insulation is 270mm. The panels are bonded to the inner hull by means of resin ropes, in order to anchor the insulation and spreading evenly the loads.
The shipowner and shipyard’s names are not yet undisclosed.
