Embodiment Construction

[0019] see Figure 1 to Figure 5 , the heavy-duty ocean engineering crane base proposed by the present invention is located at the stern of the hull, and its own weight is 4000 tons. In the fixed stern mode, the turning radius is 43m and the lifting capacity is 4000 tons; in the full turning mode, the turning radius is 33m and the lifting capacity is 3500 tons.

[0020] The proposed crane base is a cylindrical structure with a diameter of 24.3m and a height of 13.40m. The upper part of the cylinder is a steel plate with a wall thickness of 45mm and the material is EH36-Z35, and the lower part is a steel plate with a thickness of 30mm and 45mm and the material is EH36. The bottom of the cylinder is welded on the platform deck 14 which is 9100mm away from the baseline, and its upper part still has a 2.2m high cylinder wall on the A deck 2.

[0021] For specific base structure, see figure 1 and figure 2 : taking the main deck 1 as the base surface, laying a deck bottom plate ...

Abstract

The invention provides an assembly method of a chassis of a heavy oceaneering crane of a deepwater pipe-lay crane vessel. The lower structure, the middle structure and the upper structure of the chassis are built layer by layer, or the left half parts and the half right parts of the lower structure and the middle structure are built separately, or the upper structure and the middle structure are divided into an upper part, a lower part, a left part and a right part firstly, then the four parts are built separately, and then the upper structure is built after the four parts are assembled. The invention has the advantage that the chassis of the heavy oceaneering crane of the deepwater pipe-lay crane vessel is assembled effectively by adoption of the segmenting process, and a better process is provided for the building of a huge vessel.

Description

technical field [0001] The invention relates to a method for assembling a crane base of a ship, in particular to a method for segmentally assembling a base of a heavy-duty marine engineering crane on a deep-water pipe-laying crane ship. Background technique [0002] At present, there is no reference process for the construction of a heavy-duty marine engineering crane base weighing 813.20 tons on a large deep-water pipe-laying crane ship. Contents of the invention [0003] The main task of the present invention is to provide a method for assembling the base of a heavy-duty marine engineering crane on a deep-water pipe-laying crane ship, specifically a method of segmented construction to realize the construction of the base of a heavy-duty marine engineering crane on a deep-water pipe-laying crane ship . [0004] In order to solve the above technical problems, the main task of the present invention is to provide a method for assembling a heavy-duty marine engineering crane...
