The type B tank in construction is for the LNG fuelled 16,000 TEU container ship series. Each ship is equipped with an independent type B tank. There are 8 sets of this series in total. Designed by DSIC Design Institute, with fully independent intellectual property rights, the tank capacity is 13,000 cubic meters, the design temperature is -163°C, the design pressure is 0.7Bar, the main shell material is NV9Ni/a steel, and the internal pipeline is 316L steel. It is registered with DNV Classification Society. Compared with the traditional type C tank, the type B tank has the advantages of high-capacity utilization, flexible and diverse design.
The type B tank is equipped with a TiG patented panel system, 380mm thickness pre-fabricated Expanded Polystyrene panel with Polyurethane foam insulation system, the panel system is performed as:
1) Thermal insulation, to protect the hull from temperatures below those allowable and limit the heat flux into the tank.
2) Spray shield, deflect any liquefied gas fuel down into the partial secondary barrier (drip tray).
