Description

Technical Field

[0001] The present invention relates to shipbuilding, and in particular to a special hoisting device and a hoisting method for hoisting a regasification module of an FSRU ship as a whole. Background Art

[0002] FSRU (floating storage regasification unit, FSRU for short) is a ship equipped with a regasification unit. Compared with the traditional LNG transport and regasification plant model, the floating regasification method for receiving and processing LNG is more flexible and convenient, and the cost-effectiveness is relatively high. FSRU ships can be moored on the deep seabed for a long time, reducing the current draft restrictions on LNG ships at shore terminals. FRSU ships use themselves as storage and transportation equipment, and the regasification unit is generally placed on the deck.

[0003] The regasification module is one of the most critical equipment of the FSRU ship. Its entire lifting weight is about 800t, and it has 4 lifting points. The maximum force of a single lifting point is nearly 240t, so a shackle with a rated load of at least 240t is required. In the prior art, Chinese invention patent 202010522443 relates to a fixing and disassembling device for a spare Kent shackle of a ship, wherein the Kent shackle is positioned on the side of a conical boss and the shackle hole of the Kent shackle is in contact with the semicircular arc and two parallel line segments on the side of the conical boss respectively; the bottom plate is provided with a top pressure screw for disassembling the middle cross bar, and the center of the pressure plate is provided with a discharge hole for ejecting the middle cross bar. The above structural composition realizes the secure fixation of the spare Kent shackle and facilitates the disassembly of the Kent shackle. However, this shackle cannot be used in the lifting of the regasification module, cannot meet the verticality and stability requirements, and cannot meet the load requirement of 240t. Therefore, there is no shackle that can meet the lifting requirements at the construction site. If such a large-tonnage standard shackle is purchased again, there will be problems of high cost and long cycle. Therefore, a special lifting device is needed to ensure the smooth lifting of the regasification module, save production costs, and avoid affecting the ship construction cycle.

[0015] The present invention also relates to a method for hoisting a regasification module on a FSRU ship as a whole. The overall weight of the regasification module on the FSRU ship is 800 tons. A regasification module hoist is provided at each of the four corners of the upper part of the regasification module. The method comprises the following steps:

[0016] The first step is to design and manufacture a special lifting device, which structurally includes a main board, a body board, a first connecting plate and a second connecting plate. Two main boards arranged in parallel are vertically cross-connected with two body boards arranged in parallel, so that two rectangular connecting grooves on the main board connecting portion on the main board are respectively correspondingly clamped in two rectangular connecting grooves on the body board connecting portion on the body board. The main board and the body board are fixed into one body by welding the main board connecting portion and the body board connecting portion. A main board hanging hole is provided on each main board, and two body board hanging holes are provided on each body board.

[0017] The second step is to install a special lifting device, connect the mainboard lifting hole of the mainboard on the special lifting device to the regasification module hanging bracket through a pin shaft, so that the regasification module hanging bracket is located between the two mainboards (1) of the special lifting device, and then set four special lifting devices corresponding to the regasification module hanging brackets at the four corner positions on the regasification module;

The 400t lifting row on the 3# hook of the lower car is connected to the 500t lifting beam through wire ropes, and the endless rope loop is hung under the 500t lifting beam.

[0019] Step 4: Connect the gantry crane to the regasification module, align the centerline of the gantry crane's main beam with the left-right centerline of the regasification module, and position the upper and lower trolleys directly above the left and right lifting points of the regasification module, and use steel wire ropes to connect the special lifting equipment;

The regasification module lifting code is located between the two main boards. The upper two lifting holes of the body of the special lifting equipment are connected to the 120t wire rope through a 120t pin shaft respectively. The 120t wire rope is located between the two body boards. When the wire rope is lifted, the design of the lifting holes on the two body boards meets the angle requirements, so that the wire rope remains vertical to the regasification module during lifting, and will not tilt or shake during the lifting process, which greatly increases the lifting stability and safety.

[0024] 3. While meeting the overall hoisting requirements of the regasification module, the method of the present invention also avoids the purchase of large-tonnage standard shackles, ensuring that the wire rope and the upper platform of the regasification module are always in a 90-degree vertical state during the hoisting process, thereby achieving safe hoisting of the module, greatly reducing costs, and saving construction period.
