Embodiment Construction

[0049] Such as Figure 1 to Figure 6The upper and lower floating body separation process of an offshore platform is shown, which is used to separate the upper and lower floating bodies 2 of the offshore platform. The offshore platform includes the upper floating body 1 and the lower floating body 2. Before the separation of the offshore platform, the upper floating body is 100m long, 48m wide, and 14m deep. , the structural weight is 16913.9T, the towing draft is 7.2m, the length of the lower floating body is 75m, the width is 48m, the molded depth is 6m, and the structural weight is 5022.1T. After the offshore platform is separated, the draft of the upper floating body 1 is 10.087m, and the molded depth of the lower floating body 2 6m, several locking devices 21 are installed on the lower floating body 2, and the locking devices 21 include a locking frame and locking pieces arranged in the locking frame.

Abstract

The invention relates to an upper floating body and lower floating body separation process of an offshore platform. The separation process comprises the following steps that firstly, a separation water area near a wharf is selected and subjected to field survey and cleaning; 2, lower floating body separation preparation: S1, lower floating body lifting lug installation and sling configuration; s2, a lower floating body locking device buffer assembly is arranged; s3, a lower floating body measuring scale is arranged; s4, injecting water into the lower floating body, ventilating, and installing a drainage pipe and a submersible pump; thirdly, the offshore platform is towed to a separation water area; 4, separating upper and lower floating bodies; and step 5, ending. The upper floating body and the lower floating body are separated at the wharf, compared with a wind field, the wharf equipment resources are sufficient, the surrounding environment is controllable, the cost is greatly saved while it is guaranteed that the upper floating body and the lower floating body are separated smoothly and safely, and the separation risk of the upper floating body and the lower floating body is reduced; the screened separation water area meets the requirements of the separation water area through tidal changes, and meanwhile separation work of the upper floating body and the lower floating body is conducted, and follow-up separation operation is facilitated.

Description

technical field [0001] The invention relates to the technical structure field of offshore operations, in particular to a process for separating upper and lower floating bodies of an offshore platform. Background technique [0002] The 2500T bottom-mounted offshore wind power installation platform (hereinafter referred to as 2500T) has a total length of 100 meters, a molded width of 48 meters, and a molded depth of 14 meters. It is equipped with DP1 dynamic positioning and a full-slewing crane with a maximum lifting capacity of 2500T. Comprehensive engineering The construction capacity ranks first among similar platforms in the world. [0003] Before the upper and lower floating bodies of 2500T are separated, the upper floating body is 100m long, 48m wide, 14m deep, with a structural weight of 16913.9T, and a towing draft of 7.2m; the lower floating body is 75m long, 48m wide, 6m deep, and a structural weight of 5022.1T. [0004] In order to speed up the test progress of the...
