Problems solved by technology

Therefore, the hoisting test of the crane is a comprehensive and complicated project.
The existing lifting test method for heavy-lift ships is generally to transport huge heavy objects from the wharf to the ship, and then use the hoisting crane to cooperate with the huge heavy objects for testing, but there are certain defects in this test method: In this test method, a huge weight needs to be transported to the ship, and then the lifting test is carried out. The process is relatively complicated. At the same time, external heavy objects need to be used, which will increase the cost, and the transportation of heavy objects will increase the labor intensity.

Embodiment

[0039] The simple type hoisting test method of the heavy-lift ship of the present embodiment, the method comprises the following steps:

[0040] (1) Weighing test hoisting weight: weighing the test hoisting weight approved by the owner ship inspection, 90t lifting / self-propelled hatch cover P25, 90t lifting / self-propelled hatch cover P26, 34t second deck D5, 34t second deck D 12, 30t second deck D 7, 30t second deck D6, 13.5t 1x hanging block, 45t 1x hanging block and 50t 1x hanging block.

[0041] (2) Overload test:

[0042] a. Load lifting test of the main hook of the 1# gram crane: the hoisting weight includes lift-off / self-propelled hatch cover P25, lift-off / self-propelled hatch cover P26, second deck D 5, second deck D 6, and second deck D 12; if figure 1 As shown, use the 1# gram crane to hoist the hatch cover P26 to FR106, that is, move the hatch cover to the stop position, and then use the 1# gram crane to overlap the P25 block on the hatch enclosure and lock it tig...

Abstract

The invention relates to a cost-saving type load test method for a heavy lift vessel. The method includes the following steps of (1) weighing of a test load, (2) an overload test, (3) a load test, (4) a braking test, (5) a test of a safety device, and (6) inspection after the tests. Compared with a traditional test method, the cost-saving type load test method for the heavy lift vessel has the advantages that no external weight is needed, lift-away / self-propelled hatchway covers, second decks and 1x hoisting blocks on the heavy lift vessel are directly used, and therefore cost is reduced, labor intensity is greatly lowered, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a lightweight lifting device for a heavy-lift ship. [0002] experiment method. Background technique [0003] With the needs of the development of marine industry, offshore operations are becoming larger and larger, which requires higher and higher requirements for large offshore lifting equipment. The manufacturing requirements of the lifting crane on the heavy-lift ship are high and difficult. Among them, the lifting test of the lifting crane is the most important part. The purpose of the test is to check the installation integrity, correctness and working reliability of the lifting crane. And verify whether the performance indicators meet the requirements of the design and test program. Therefore, the hoisting test of the crane is a comprehensive and complicated project. The existing lifting test method for heavy-lift ships is generally to transport huge heavy obj...
