C-shaped independent liquid tank in liquefied gas ship

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...

AI Technical Summary

Problems solved by technology

Because the C-type independent liquid tank and the liquefied gas ship are independent of each other, if the coordination between the two is not done well during the ship movement, it will cause damage to the structure of the C-type independent liquid tank or the hull structure, and then cause the leakage of the liquefied gas carried, which will cause Bring considerable losses or even irreparable consequences to the transportation of liquefied gas ships
