Lifting appliance for integrally lifting FSRU ship regasification module

Abstract

The invention relates to a lifting appliance for integrally lifting a regasification module of an FSRU ship, the overall weight of the regasification module on the FSRU ship is 800T, four corners of the upper part of the regasification module are respectively provided with a regasification module hanger, and the lifting appliance structurally comprises a main plate (1), a body plate (2), a first connecting plate (5) and a second connecting plate (6), the two main plates (1) arranged in parallel and the two body plates (2) arranged in parallel are perpendicularly connected in a crossed mode, the two rectangular connecting grooves in the main plate connecting parts are correspondingly clamped in the two rectangular connecting grooves in the body plate connecting parts respectively, and the main plates (1) and the body plates (2) are welded and fixed into a whole through the main plate connecting parts and the body plate connecting parts. A first pin shaft penetrates through the main plate lifting hole to fix the bottom of the lifting appliance on the regasification module hanger; the invention further relates to an integral hoisting method of the FSRU ship regasification module. The rated bearing capacity of the special lifting appliance is 240 t or above, and the requirements for load, perpendicularity and stability of integral lifting of the regasification module are met.

Description

technical field [0001] The invention relates to ship building, in particular to a special hoisting tool and a hoisting method for overall hoisting of FSRU ship regasification modules. Background technique [0002] FSRU (floating storage regasification unit, FSRU for short) refers to a ship with a regasification unit. Compared with the traditional mode of LNG transportation and regasification plant, it is more flexible and convenient to receive and process LNG by means of floating regasification, and the cost-effectiveness is relatively high. The FSRU ship can be single-point moored on the deep-sea seabed for a long time, reducing the draft limit of the current shore terminal to the LNG ship. The FRSU ship itself is used as a storage and transportation device, and the regasification unit is generally placed on the deck. [0003] The regasification module is one of the most critical equipment on the FSRU ship. Its overall lifting weight is about 800t, and there are 4 lifting ...

AI Technical Summary

Problems solved by technology

However, this kind of shackle cannot be used in the lifting of the regasification module, and cannot meet the requirements of verticality and stability, let alone the load requirement of 240t

Therefore, there are no shackles that can meet the hoisting requirements at the construction site. If such a standard shackle with such a large tonnage is repurchased, there will be problems of high cost and long cycle time.
