Offshore structure performance monitoring and operation and maintenance decision method, device and system

Abstract

The invention relates to an offshore structure performance monitoring and operation and maintenance decision-making method, a device and a system, in order to solve the problems of lacking accuracy and timeliness in safety monitoring of offshore engineering structure, no pertinence in operation and maintenance plan, high cost and poor effect in patrol inspection at sea, and the like. The technicalscheme of the invention is as follows: a method for monitoring offshore structure performance and making operation and maintenance decision is characterized in that: wind wave current load and waterlevel change around the offshore structure collected by a real-time environmental load collecting device are obtained; according to the wind, wave and current loads and water level changes, the straindata of the key components or nodes of offshore structures are obtained by finite element modeling. The strain data of key components or nodes of offshore structures collected synchronously by the structural strain acquisition device are obtained and compared with the strain data of key components or nodes of offshore structures obtained by solving, and the failure of any components or nodes is judged according to the difference degree.

Description

technical field [0001] The invention relates to a method, device and system for offshore structural performance monitoring and operation and maintenance decision-making. It is suitable for the field of marine engineering and structural health monitoring, especially the structural monitoring and operation and maintenance decision-making of the electrical platform of offshore wind farms. Background technique [0002] Ocean engineering structures face a variety of environmental loads, such as wind, waves, currents, earthquakes, etc., and the structural response and failure damage have strong uncertainties. At present, the control of the safety of marine structures is more concentrated in the design stage, and there is a lack of synchronous monitoring of the actual environmental load data and response data during service, so it is difficult to infer the actual force and response of the structure. In addition, the cost of offshore operation and maintenance is much higher than th...
