IMO Type C Single / Double Shell Tank
The IMO type C-Tank type LNG tank is the most common tank technology for LNG fuel containment, typically used as a fuel tank for cargo vessels. The construction is similar to a pressure vessel, based on the cylindrical design for optimal material usage vs. internal pressure, with a maximum design pressure of 10 bar for marine applications.
It is the dominant design in LNG carriers. The C-type tank needs insulation to keep the content cold and minimize LNG boil-off. There are two types of insulation used, double shell with vacuum and insulation in annular space and single shell with spray insulation on the outer layer to hold the low temperature. It called 9%Ni cryogenic tank, for LNG storage. Used for LNG barges, chemical carriers, LNG fuel tanks with TCS system,FGSS system, or LNG bunkers.
