For LNGC, two types of cargo containment system are mainly produced : MarkⅢ and NO96. SAMWOO MCP manufactures key parts of the cargo containment system of both models in state-of-the-art facilities and secure an exclusive position as a reliable partner through perfect quality control system.
We have been participating in the research and development stage for additional types under development and are actively participating in efforts to preoccupy the market and expand the market.
Moreover, in the industry where low carbon and eco-friendliness are emphasized, we are constantly striving for research and development to efficiently reduce costs and improve competitiveness.

MARKIII
MARKIII
The Mark III membrane system is a containment and insulation
system, directly supported by the vessel’s hull structure. It is composed of a
primary corrugated stainless steel membrane, positioned on top of prefabricated
insulation panels, including a complete secondary membrane made of composite
material. This modular system employs standard
prefabricated components that can accommodate any shapes and capacities of tanks.
They are designed for mass production techniques and easy assembly.

NO96 TYPE
NO96 TYPE
The primary and secondary membranes are made of Invar, a 36% nickel-steel alloy, 0.7mm
thick. The primary membrane contains the LNG cargo, while the secondary membrane,
identical to the primary, ensures a 100% redundancy in case of leakage. Each of the
500mm wide Invar strakes is continuously spread along the tank walls and is evenly
supported by the primary and the secondary insulation layers.
With the approval of GTT, SAMWOO MCP manufactures and supplies all metal joint
parts (e.g., coupler) for a cargo containment system.

NO96 SUPER+ TYPE
NO96 SUPER+ TYPE
In the case of the newly developed NO96 Super+ type of GTT, SAMWOO MCP joined the
research and development project at the beginning and contributed to determining product
specifications.

NEXT1 type
NEXT1 type
The NEXT 1 membrane system, a new type of LNGC CCS under
development, is made up of a fully redundant membrane and insulating system,
directly supported by the ship’s inner hull. It includes two independent metallic
membranes, both supported by a layer of insulating material.
The primary barrier, directly in contact with the cargo, is a corrugated
stainless steel membrane, adapted from GTT’s Mark technologies, whereas the
secondary barrier, achieving full redundancy of the tightness function, is a Fe-36%
Ni alloy membrane. With the approval of GTT, SAMWOO MCP will manufacture and supply
all metal joint parts for a cargo containment system.
