Problems solved by technology

[0002] Large storage tanks (such as C-type independent liquid tanks of liquefied gas ships, etc.) are mostly supported and placed on rigid saddles during shipping. The problems with this method are; On the seat, the hull and storage tank at the saddle will produce excessive concentrated stress; second, when the large storage tank shrinks, expands, and the hull deforms, it is easy to cause excessive stress on the hull and storage tank; third, when When the ambient temperature is too high, the storage tank must be sprayed with water to cool down; Fourth, the type A machinery space connected to the cargo space, drinking water tanks and other cabins must be separated by isolation cabins or A-60 grade insulation

Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] A concave watertight water jacket 1 is set on the hull deck. The cavity of the water jacket coincides with the longitudinal lower half section of the storage tank 8. The middle is semi-cylindrical or over half-cylindrical, and the two ends are 1 / 4 spherical or over 1 / 4 Spherical shape, the inner diameter of the water jacket is slightly larger than the outer diameter of the storage tank, usually 50-100 mm larger, and the upper edge of the junction of the water jacket cavity and the hull deck 7 is provided with a water-retaining edge 5 that protrudes upwards and is higher than the hull deck surface. The water edge is integrated with the hatch fence; in addition, the two ends of the water jacket cavity can also be ellipsoidal, dish-shaped or plane-shaped for the convex heads at both ends of the storage tank; elastic pads are set in the water jacket ca...

Abstract

A support device of semi floating storage tank used on ship is featured as setting a concave watertight water bath on deck of ship, making section cavity of water bath fit with bottom half section of gas storage tank and placing elastic raising blocks at section cavity surface of water bath.

Description

technical field [0001] The invention relates to a marine water cushion type semi-floating storage tank support device for carrying large liquefied gas, compressed gas storage tanks or other liquid storage tanks. Background technique [0002] Large storage tanks (such as C-type independent liquid tanks of liquefied gas ships, etc.) are mostly supported and placed on rigid saddles during shipping. The problems with this method are; On the seat, the hull and storage tank at the saddle will produce excessive concentrated stress; second, when the large storage tank shrinks, expands, and the hull deforms, it is easy to cause excessive stress on the hull and storage tank; third, when When the ambient temperature is too high, the storage tank must be sprayed with water to cool down; Fourth, the type A machinery space connected to the cargo space, the drinking water tank and other compartments must be separated by a cofferdam or A-60 class insulation.
