Abstract

The invention relates to a lower floating body strength experiment method. A lower floating body comprises a ballast tank and empty tanks. The two empty tanks are located on the two sides of the ballast tank. The method is characterized in that a specific strength test method comprises the following steps: S1, injecting water; S2, installing an experiment pipe; S3, performing exhausting; S4, performing pressurizing; S5, performing observation; S6, maintaining the pressure; and S7, ending the experiment. The process is safe and reliable, operation is easy and convenient, efficiency is high, environmental pollution can be greatly reduced, and the experiment process is controllable; the experiment is initiated in the industry that the strength test of the lower floating body is completed within 3-4 days from the beginning of water injection, the test can effectively reduce various operation risks in the test process, and pollution of sewage to a cabin is avoided; and through simple transformation of infrastructures, subsequent ships can more effectively utilize the test method of the ship, the test time and the labor cost are saved, and great reference significance is achieved for similar ships with diving requirements.

Description

technical field [0001] The invention relates to the field of self-elevating offshore wind power installation platforms, in particular to a method for testing the strength of a lower floating body. Background technique [0002] The 2500T bottom-mounted offshore wind power installation platform is the world's first new-generation bottom-mounted jack-up offshore wind power installation platform. It inherits all the functions and advantages of the traditional jack-up wind power installation platform. Avoid the risk of traditional spud shoe pile extraction. [0003] The biggest feature of this platform is the embedded lower floating body it adopts; when sailing, the lower floating body is embedded in the hull to complement the hull shape and reduce navigation resistance; when working, the lower floating body dives into the water 50m, as an independent large contact area The spud shoes make the ship stand more stable. In order to ensure the underwater performance, tightness and ...
