Problems solved by technology

[0006] However, in the above-mentioned offshore transportation system, the LNG transportation is carried out in a side-by-side manner, which is only suitable for sea areas with relatively gentle sea conditions. In addition, the cargo tank loading height of the shuttle LNG ship has a certain limit range, and thus also Not suitable for sea areas with poor sea conditions

Abstract

The invention discloses a shuttle LNG ship for marine LNG transportation. The shuttle LNG ship comprises a ship body, an operation system and a gas-phase tube, wherein the operation system is mounted inside the ship body; the operation system comprises an LNG transportation subsystem which is mounted at a fore peak deck part, a surrounding subsystem arranged inside a cargo cabin, thrusting subsystems which are respectively mounted inside a front propulsion equipment cabin and a tail propulsion equipment cabin, and a power positioning subsystem which is mounted inside an engine room; the LNG transportation subsystem comprises two liquid-phase tubes; two ends of each of the two liquid-phase tubes are respectively connected with the cargo cabin and an external FLNG device during operation; two ends of the gas-phase tube are respectively connected with the cargo cabin and the FLNG device during operation. By changing the main size of the shuttle LNG ship disclosed by the invention, the ship body can be elongated to be applicable to severe ocean conditions, and serial connection between the FLNG device and the shuttle LNG ship can be achieved; in addition, the surrounding system is arranged inside the cargo cabin, then the cargo cabin can carry low-temperature liquid LNG cargo, and the surrounding system can meet the requirement that the loading liquid level height of the cargo cabin is not limited.

Description

technical field [0001] The invention relates to the field of marine transportation, in particular to a shuttle LNG ship used for marine LNG transportation. Background technique [0002] The shuttle LNG (liquefied natural gas, hereinafter referred to as LNG) ship is a means of transportation to realize offshore LNG transportation, and transports the LNG produced by the FLNG (floating liquefied natural gas, hereinafter referred to as FLNG) device to an onshore terminal or FSRU (floating storage gas storage unit). chemical device, hereinafter referred to as FSRU). [0003] Offshore LNG transportation operations are divided into two ways: two ships alongside and tandem. Side by side, the two ships are side by side. The hulls are connected by multiple mooring cables, and multiple sets of fenders are installed to prevent collisions caused by the relative movement between the two hulls. It is suitable for mild sea conditions. In the operation of tandem transportation, the two shi...
