Problems solved by technology

[0003] At present, for the evaluation of the deformation and inclination of pile legs on offshore platforms, strain gauges are usually installed on each pile leg to sense the deformation of a single pile leg respectively, and by obtaining the deformation information of each pile leg, it is determined whether it is necessary to adjust the plugging and unplugging of the pile leg situation, this analysis adopts a single-point adjustme

Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0041] This embodiment provides a method for evaluating the inclination of an offshore platform. Through joint analysis and evaluation of the relationship between the inclination of the offshore platform and the deformation of the pile legs, the overall inclination of the offshore platform due to the deformation of the pile legs can be obtained, thereby effectively guiding the offshore platform. The pile leg insertion and extraction operation of the lifting ship.

[0042] The overall idea of ​​the method is: the evaluation in the present invention does not routinely express the evaluation result in the form of a parameter, but expresses the evaluation result of the inclination of the ocean platform in the form of an image; the inclination state of the ocean platform can be intuitively displayed. In this embodiment, the tilt state matrix of the offshore pla...

Abstract

The invention provides a method for evaluating inclination of ocean platforms, and belongs to the technical field of ocean engineering. The method includes monitoring measurement data of strain sensors on legs in real time to acquire inclination state matrixes of the ocean platforms; performing association analysis on the inclination state matrixes; acquiring integral inclination images of the ocean platforms to visually display inclination states of the ocean platforms. The method has the advantages that auxiliary decisions can be made by the aid of the method with appropriate safety coefficients, so that operators can master deformation trend conditions of the legs; warning can be carried out when preset deformation values are exceeded, accordingly, the legs can be timely adjusted, and pile pitching and extracting operation on the legs of lifting ships of the ocean platforms can be effectively guided.

Description

technical field [0001] The invention relates to a method for evaluating deformation and inclination, in particular to an evaluation method for inclination of an ocean platform, and belongs to the technical field of ocean engineering. Background technique [0002] Offshore platforms support and balance weight through pile foundations, and the platform load is usually carried by multiple pile legs. During the process of lifting and pulling out piles on the offshore platform, the pile legs will be deformed due to tilting and extrusion, causing the platform to tilt. In order to avoid pile leg jamming, the deformation of each pile leg is usually monitored. By evaluating its deformation and inclination, an early warning is given in time, and the operation of the pile leg insertion and extraction of the offshore platform lifting ship is guided, so as to ensure the safety of the platform. Safe operation, reduced maintenance costs, improved equipment integrity, and extended service ...
