Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a marine lashing device and method for an independent liquid cargo tank barge. Background Art

[0002] The independent cargo tank of the LNG bunkering ship is a cargo tank independent of the main hull structure. In order to adapt to the trend of modular construction, the independent cargo tank is a large-scale modular intermediate product with independent structure and function. It is regarded as an integrated section of "hull, outfitting and coating". It is built in parallel with the main hull structure and hoisted to the main hull for installation during the loading stage to shorten the dock construction period. However, due to the special characteristics of the main material of the independent cargo tank, which is high-strength and low-temperature resistant steel and the entire surface of the tank body is covered with a flammable material insulation layer, it is often built in a specific place. After the whole tank is shipped back to the factory by barge, it is hoisted and loaded, and closed and connected with the main hull structure. Since the surface of the tank body is covered with a flammable material insulation layer, and safety during the shipping process must be ensured, the independent cargo tank needs to be effectively tied, no open flame welding can be performed on the outer surface of the independent cargo tank, and the welding workload with the barge deck surface should be minimized to avoid damage to the insulation layer or fire.

[0003] At present, the traditional steel structure lashing form cannot be used for barge sea transportation lashing of objects with special materials and special structures of independent liquid cargo tanks. If the whole lashing is performed by ropes, there are certain safety risks due to the large size of the independent liquid cargo tanks. In addition, if the ropes are tied too tightly, the insulation layer will be damaged, and if the ropes are tied too loosely, there is a risk of displacement and overturning. If rigid welding is performed through the support seat at the bottom of the independent liquid cargo, the support seat body structure will be damaged, and a large amount of open flame operations may cause the flammable insulation layer to burn and explode. Therefore, it is necessary to find a method with high safety and simple construction to solve the problem of using barges for sea transportation of LNG bunkering independent liquid cargo.

7. The marine lashing device for independent liquid cargo tank barge according to claim 1 is characterized in that: A rubber 12 is provided between the top plate and the limiting structure, and a rubber is provided between the pad and the clamping groove of the limiting structure.

8. The marine lashing device for independent liquid cargo tank barge according to claim 1 is characterized in that: The connection between the notch of the clamping plate and the pad is located at the center line of the pad, the stop block C is symmetrically arranged about the center line of the anti-longitudinal tilt support, and two stop blocks C are arranged at the ends of the long side direction of the limiting structure of the anti-longitudinal tilt support.

9. The marine lashing device for independent liquid cargo tank barge according to claim 1, characterized in that: The independent liquid cargo tank is a Type B tank.

10. A method for lashing an independent liquid cargo tank barge by sea, characterized in that: The use of the independent liquid cargo tank barge marine lashing device as claimed in claim 5 comprises the following steps: S1, according to the position and number of the bottom supports of the independent liquid cargo tank, determine the position and number of the I-beam bottom support, stop block A, stop block B and stop block C, and cut the parts according to the size; S2, assembling the I-beam bottom support, stop block B and stop block C assembly; S3, clear the barge deck, and mark the positioning marks of various lashing devices on the barge deck in advance according to the positions of the load-bearing laminated timbers, put the I-beam bottom support in place in advance, and place the pads on the upper plate of the I-beam base in advance; S4, hoist the independent liquid cargo tank onto the barge, make the load-bearing laminated wood on one side of the independent liquid cargo tank close to the upper plate of the I-beam bracket, adjust the thickness of the pads, and make the independent liquid cargo tank stably fall on the upper plate of the I-beam bracket; S5, put up three-proof cloth at the construction site to isolate the independent liquid cargo tank from the construction open flame environment, weld the stop block A, and weld the I-beam support bottom to the barge deck firmly; S6, place rubber pads between the top plate of stop block B and the limit structure, pull three-proof cloth on the construction site to isolate the independent liquid cargo tank from the open flame construction environment, and weld the main plate of stop block B to the barge deck; S7, place rubber pads between the pad and support seat of the stop block C, pull three-proof cloth on the construction site to isolate the independent liquid cargo tank from the open flame construction environment, and weld the clamping plate of the stop block C to the barge deck; S8, complete the lashing of the independent liquid cargo tank on the barge and implement marine transportation; S9, after the independent liquid cargo tank is transported to the destination, three-proof cloth is pulled on the construction site to isolate the independent liquid cargo tank from the construction open flame environment, and the welds between stop block A, stop block B, stop block C and the barge deck are cut off. After all welding constraints are released, the independent liquid cargo tank can be hoisted and loaded.
