Abstract

The invention provides a C-shaped independent liquid tank in a liquefied gas ship. The C-shaped independent liquid tank comprises two cylindrical liquid tank bodies which are arranged side by side and fixed together; domes are arranged on the top surfaces of the two liquid tank bodies correspondingly; material openings are formed in the domes correspondingly; deep well pumps extending into the liquid tank bodies are arranged on the material openings correspondingly; fixed supporting seats and sliding supporting seats which correspond in position are arranged on the bottom surfaces of the two liquid tank bodies correspondingly; the fixed supporting seats and the sliding supporting seats are all of circular arc-shaped structures arranged in the width directions of the liquid tank bodies; a plurality of floating stopping devices are arranged at the tops of the two liquid tank bodies correspondingly; laminated wood is arranged at the bottoms of the fixed supporting seats and sliding supporting seats correspondingly; and liquid accumulation grooves are formed in the inner bottom faces of the two liquid tank bodies correspondingly. The C-shaped independent liquid tank is reasonable in structure, safety and reliability of the position relationship between a tank body structure of the liquid tank and a hull can be guaranteed, loads are effectively transmitted, and all kinds of stress strain and fatigue damage of the liquid tank and a hull structure do not occur, so that the ship can safely conduct transportation.

Description

technical field

[0001] The invention relates to a liquefied gas ship, in particular to a C-type independent liquid tank in the liquefied gas ship. Background technique

[0002] The liquefied gas carrier with C-type independent liquid tank is a new type of high value-added ship with broad market development prospects. The main cargoes it transports are: propane, butane, ethylene, propylene, butene, etc. as the main components of oil Hydrocarbons or a mixture of the two, and some chemical products. Type C independent liquid tank is the most common cargo containment system. Its tank-shaped liquid cargo tank conforms to the pressure vessel standard and is suitable for shipping liquefied petroleum gas with a boiling point higher than -104 degrees. There is no secondary shielding. Its specific structure is two juxtaposed A cylindrical liquid tank structure set and fixed together. The C-type independent liquid tank does not constitute a part of the hull structure, and needs to be...
