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

[0050] Such as Figure 1-15 As shown, this embodiment discloses an LNG pre-operation platform outside the 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 .

[0051]The material storage and transportation platform 1 is equipped with platform ladders 141 , 142 and a material lifting device 15 .

[0052] The top of the material storage and transportation platform 1 is divided into three functional areas: storage work area 1A, channel area 1B, and material loading area 1C. The uniform load of storage work area 1A is not less than 250Kg / m2, the area is not less than 300m2, and the Not less than 10m, the uniform load of passage area 1B is not less than 300Kg / m2, the passage width is not less than 4m, the uniform load of feeding area 1C is not less than 300Kg / m2, and the length and width are not less than 4m.

Embodiment 2

[0065] Such as Figure 1-15 As shown, the present embodiment discloses a pre-operation method for LNG outside the cabin of a membrane-type containment system, which specifically includes the following steps:

[0066] S1, build a 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 opening of the temporary process hole A1 is not greater than 100mm;

[0067] S2, building a constant temperature and humidity room 2 based on the material storage and transportation platform 1;

[0068] S3, installing the entry platform 3 based on the material storage and transportation platform 1;

[0069] 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;

[0070] S5...

Abstract

The invention discloses an outboard pre-operation platform of an LNG ship enclosure system. The pre-operation platform comprises a material storage and transportation platform, a constant-temperatureand constant-humidity room and a cabin entering platform; the material storage and transportation platform is arranged at the position, directly facing the temporary process hole, outside an LNG cabin; the constant-temperature and constant-humidity room is arranged on the material storage and transportation platform; and the cabin entering platform is in communication with the constant-temperatureand constant-humidity room and the temporary process hole. According to the outboard pre-operation platform of an 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 shipbuilding, and in particular relates to an external pre-operation platform of an LNG ship containment system. Background technique [0002] The LNG ship containment system is generally pre-worked in the cabin, and it is installed directly after the pre-work is completed. However, with the development of the miniaturization of LNG ships, especially the increasing demand for the construction of direct river-to-sea LNG carriers and LNG fuel tank conversion ships, The space of LNG tanks of some ships is small, which can no longer satisfy the materials and equipment for the pre-operation of the containment system in the LNG tanks, which brings great inconvenience to the smooth construction of LNG tanks. [0003] In the prior art, there is no special method for the pre-operation of the containment system of the smaller LNG tank. At this time, the pre-operation of the containment system in the cabin has the f...
