Problems solved by technology

[0004] Since the above ships will encounter various wind waves and various temperatures during sea transportation, when the ship is swayed by the waves or when the liquefied petroleum gas is loaded with thermal expansion and contraction, there is a very high potential safety hazard

Embodiment Construction

[0012] Such as figure 1 As shown, a prismatic cylindrical tank 2 is arranged along the cross section of the hull 1 in the hull 1, and the bottom, top and sides of the tank 2 are arc-shaped, thereby avoiding sharp corners.

[0013] Between the bottom of the tank body 2 and the hull 1, several bottom elastic supports 3 are uniformly distributed, and between the top of the tank body 2 and the hull 1, several anti-floating elastic supports 4 are evenly distributed.

[0014] Between the middle part of the top of the tank body 2 and the hull 1, a first anti-swing support 5 for limiting the lateral movement of the tank body on the hull is arranged. A second anti-swing support 6 for limiting the lateral movement of the tank body on the ship body is arranged between the middle part of the bottom of the tank body 2 and the hull 1 .

[0015] The tank body 2 can be installed on the load-bearing block above the steel load-bearing base, the load-bearing block is a thin plate type phenol re...

Abstract

The invention discloses a safety tank ship used for transporting liquefied petroleum gas (LPG) and relates to the technical field of production of A-type tanks of LPG ships. A cylindrical tank with prismatic section along the ship body is arranged in a ship body, elastic bottom supports are arranged between the bottom of the tank and the ship body, and anti-float elastic supports are arranged between the top of the tank and the ship body. The tank can be positioned in the ship body and can be prevented from directly and rigidly colliding with the ship body, so that safety transport is facilitated.

Description

technical field [0001] The invention belongs to ship production technology, in particular to the technical field of LPG ship A-type tank production. Background technique [0002] Liquefied petroleum gas (LPG for short) ships are mainly based on the characteristics of density, viscosity, high vapor pressure, high freezing point, high volatility, high heat sensitivity, flammable, toxic, and corrosive The liquefied and reactive gases are stored in special containers for safe and reliable transportation, and can be loaded and unloaded in a liquefied state. Therefore, the craft of designing and building ships for transporting such ships is very complicated. [0003] There are usually three types of storage requirements for LPG ships used for transportation: full-pressure type, with a design temperature of -10°C and a working pressure of 1.76MPa; semi-cooled / half-pressure type, with a design temperature of -50°C and a working pressure of 0.4~1.0 MPa; total cooling type, the ...
