Tank supporting structure for ships

Patent ·
OSTI ID:6554523

Hitachi Shipbuilding and Engineering Co., Ltd.'s new LNG-cargo-tank-support design avoids the need for large support members and allows thermal expansion/contraction without high stresses in the tank or the support members. The low-temperature storage tank is supported in the hull of a ship by chocks secured to and spaced peripherally around the tank and by chock-engaging members carried by the ship's hull. Pressure-resistant heat-insulating pads between the chocks and the chock-engaging members are arranged to provide sliding surfaces and support the tank horizontally and vertically. They also permit thermal contraction/expansion movements of the tank relative to the ship's hull and compensate for thermal expansion/contraction of the chocks and the chock-engaging members.
