Problems solved by technology

[0004] First, the space in the LNG tank is limited, there are very few materials and equipment that can be stacked, the turnover of materials is very slow, and the installation efficiency of the containment system is very low
[0005] Second, when the space in the LNG tank is insufficient, the pre-operation of the containment system in the tank will pose a greater safety risk in passage, transportation, and installation, which will easily cause accidents such as material bumping and people hitting, which is not conducive to the safety of the containment system put up
[0006] Third, if the pre-operation of the enclosure system is carried out directly outside the cabin, it is impossible to provide a constant temperature and humidity working environment, and the materials that have been pre-worked will also have material performance degradation due to the influence of temperature and humidity when they are transported from outside the cabin to the cabin , it is very likely to bring great quality hidden dangers after installation, and even cause leakage and explosion during ship operation

Embodiment 1

[0048]Such asFigure 1-15 As shown, this embodiment discloses a pre-operation platform outside the LNG cabin of a membrane type containment system. The pre-operation platform includes a material storage and transportation platform 1, a constant temperature and humidity room 2, and a cabin entry platform 3.

[0049]The material storage and transportation platform 1 is equipped with platform ladders 141 and 142 and a material lifting device 15.

[0050]The top of the material storage and transportation platform 1 is divided into three functional areas: storage work area 1A, passage area 1B, and loading area 1C. The uniform load of the storage work area 1A is not less than 250Kg / m2, the area is not less than 300m2, and the length and width are equal. Not less than 10m, the uniform load of the passage area 1B is not less than 300Kg / m2, the pass width is not less than 4m, the uniform load of the feeding area 1C is not less than 300Kg / m2, and the length and width are not less than 4m.

Embodiment 2

[0063]Such asFigure 1-15 As shown, this embodiment discloses a method for pre-operation outside the LNG tank of a membrane-type containment system, which specifically includes the following steps:

[0064]S1: Build the material storage and transportation platform 1 outside the LNG tank A facing the temporary process hole A1, and the height difference between the top of the material storage and transportation platform 1 and the lower mouth of the temporary process hole A1 is not more than 100mm;

[0065]S2, build a constant temperature and humidity room 2 based on the material storage and transportation platform 1;

[0066]S3, install the cabin entry platform 3 based on the material storage and transportation platform 1;

[0067]S4. Install an air conditioning system in the constant temperature and humidity room 2 and adjust the temperature and humidity to the required working environment to form a pre-operation platform for the enclosure system;

[0068]S5: Lift the materials, tools and equipment ...

Abstract

The invention discloses a pre-operation method of an LNG ship enclosure system. The pre-operation method comprises the steps that a material storage and transportation platform is built outside an LNGcabin, and a constant-temperature and constant-humidity room is arranged on the material storage and transportation platform; a cabin entering platform is built between the constant-temperature and constant-humidity room and the LNG cabin; materials, tools and equipment required by pre-operation of the enclosure system are conveyed into the constant-humidity and constant-humidity room; and enclosure system pre-operation is conducted in the constant-temperature and constant-humidity room, and the enclosure system materials obtained after pre-operation are conveyed into the LNG cabin through the cabin entering platform. According to the pre-operation method of the LNG ship enclosure system, a reliable outboard constant-temperature and constant-humidity enclosure system pre-operation environment is provided, and the construction is more efficient and safer.

Description

Technical field[0001]The invention belongs to the technical field of ship construction, and specifically relates to a pre-operation method of an LNG ship containment system.Background technique[0002]The LNG ship containment system is generally pre-operated in the cabin and installed directly after the pre-operation is completed. However, with the development of miniaturization of LNG ships, especially the increasing demand for the construction of river-to-sea LNG carriers and LNG fuel tank conversion ships, The LNG tank space of some ships is small, and it can no longer meet the material and equipment stacking for pre-operation of the containment system in the LNG tank, which brings great inconvenience to the smooth construction of the LNG tank.[0003]There is no special pre-operation method for the containment system of a smaller LNG tank in the prior art. At this time, the pre-operation of the containment system in the tank has the following disadvantages:[0004]First, the space in ...
