Overview

A major advantage of a membrane type LNG cargo containment system like GTT MARK III and NO96 compared with an independent type CCS is the flexibility for increasing the size of the cargo tank.

However, the risk of sloshing damage to the membranes is an important key factor to consider for a membrane type LNG CCS particularly for offshore application.

Development of ultimate design capacity of LNG cargo containment system with consideration of LNG carrier onboard condition.
