Embodiment Construction

[0038] Embodiments of the present invention provide a tension self-adaptive method and device for a tension leg platform and a tension leg platform, which solves the problem of poor adaptability to working conditions in the prior art due to the fixed tension leg parameters of the tension leg platform technical problem.

[0039] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems, and the general idea is as follows:

[0040] First, detect whether the tension of the tension leg platform needs to be actively adjusted;

[0041] Then, when the tension needs to be actively adjusted, the tension adjustment parameters corresponding to the active adjustment are obtained;

[0042] Finally, based on the tension adjustment parameters, the tension of the TLP is actively adjusted.

[0043] It can be seen that due to the adoption of the technical scheme of obtaining the tension adjustment parameters corresponding to the activ...

Abstract

The invention discloses a tension self-adaption method and device for a tension leg platform and the tension leg platform. The tension self-adaption method comprises the steps that whether the tension of the tension leg platform needs to be subjected to active adjustment or not is detected; when the tension needs to be subjected to active adjustment, tension adjustment parameters corresponding to active adjustment is obtained; and the tension of the tension leg platform is subjected to active adjustment based on the tension adjustment parameters. According to the scheme disclosed by the invention, when the tension of the tension leg platform needs to be subjected to active adjustment, the tension of the tension leg platform can be adjusted temporarily, so that the movement performance of the tension leg platform in waves is more excellent, the safety of the tension leg platform is ensured, and accordingly the different use working condition requirements can be met better.

Description

technical field [0001] The invention relates to the technical field of offshore platforms, in particular to a tension-adaptive method and device for a tension leg platform and the tension leg platform. Background technique [0002] Tension leg platform (English: TensionLegPlatform; abbreviation: TLP) is a common type of offshore platform. It moors the floating platform to the seabed through several vertical tension legs, so that the floating platform can be roughly fixed in one position, and is suitable for offshore operations. to offer comfort. [0003] At present, TLPs are almost all used as floating production units, and their tasks are single, mainly offshore oil and gas processing. Therefore, the seakeeping requirements specified to meet the needs of operations are unique. Tension leg parameters such as pre-stabilization The selection of tension size, maximum tension, tension change rate, etc. is also determined. However, with the development of the times, more and mo...
