Embodiment Construction

[0024] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0025] This embodiment provides a marine liquid tank, which is a marine equipment integrating an LNG liquid tank and a tank connection place.

[0026] The tank connection space (TCS) is set on the outer peripheral side wall of the LNG liquid tank, which makes full use of the space in the width direction of the hull, and does not occupy the space in the length direction required for tank installation, which increases the space of the tank body. The loading volume is especially suitable for ships with a surplus in the width direction of the hull, which expa...

Abstract

The invention provides a marine liquid tank. The marine liquid tank comprises a tank body, a tank body joint and an interlayer pipeline. The tank body comprises an inner tank used for storing low-temperature liquid and an outer tank wrapping the inner tank, and a heat insulation interlayer is formed between the inner tank and the outer tank. The tank body joint comprises a shell and a connecting pipeline fixed in the shell, the shell is arranged on the peripheral side wall of the outer tank and extends in the axial direction of the outer tank, and a hollow containing cavity is defined between the shell and the outer tank. The interlayer pipeline comprises a plurality of pipe sections which are sequentially connected in a bent mode, the inner end of the interlayer pipeline is communicated with the inner tank, and the outer end of the interlayer pipeline penetrates through the outer tank and extends into the containing cavity to be connected with the connecting pipeline. And the tank body joint is arranged on the side wall of the outer tank, so that the space in the width direction of the ship body is fully utilized, the space in the length direction required for mounting the tank body is not occupied, the loading volume of the tank body is increased, and the cruising ability of marine operation of the ship is ensured.

Description

technical field [0001] The invention relates to the technical field of marine transport tanks, in particular to a marine liquid tank. Background technique [0002] At present, in order to meet the increasingly severe environmental challenges and reduce the emission of sulfur oxides in pollution emission control areas, the International Maritime Organization (IMO) has issued a series of regulations to control environmental pollution. As a clean energy, natural gas is more important than Traditional fuels such as diesel are more economical, so LNG (liquefied natural gas) fuel-powered ships have developed rapidly in recent years. [0003] Marine LNG fuel tanks usually adopt a vacuum horizontal container, the tank connection space (Tank ConnectionSpace, referred to as TCS) is located at the tail of the tank, and the interlayer pipeline between the inner tank and the outer tank is arranged on the inner head and outer head between. This scheme is widely used and the manufacturin...
