Safe comprehensive monitoring system for structure of offshore jacket platform

Abstract

The invention relates to a safe comprehensive monitoring system for a structure of an offshore jacket platform, belonging to the technical field of platform safety monitoring. The safe comprehensive monitoring system for the structure of the offshore jacket platform is characterized in that the comprehensive monitoring system comprises a visual display, a signal receiving module, a data comprehensive processing module, a strain monitoring system and a vibration monitoring system, wherein an FBG (Fiber Bragg Grating) strain sensor of the strain monitoring system is connected to a signal demodulation unit through a transmission optical cable; the signal demodulation unit is connected with a signal transmission device; an acceleration sensor of the vibration monitoring system is connected with a signal processing unit through a transmission cable; the signal processing unit is connected with the signal transmission device; a strain monitoring system signal and a vibration monitoring system signal are received by the data comprehensive processing module through the signal receiving module; and after data comprehensive processing is performed, a processing result is displayed on a visual display interface. The safe comprehensive monitoring system has the advantages of high sensitivity, high stability, long service life, intuitive data result, real-time on-line monitoring, capability of fulfilling early warning and the like.

Description

Technical field [0001] The invention belongs to the technical field of platform safety monitoring, and particularly relates to an integrated monitoring system for the safety of a marine jacket platform structure. Background technique [0002] At present, the marine jacket platform is a type of marine engineering structure, which provides a place for offshore operations and living for the development and utilization of marine resources. The offshore platform and jacket structure have been in service in the harsh marine environment for a long time, and bear the interaction of various loads from the marine environment (such as wind load, wave load, ice load, etc.) and the upper block and drilling equipment. In addition, they sometimes suffer damage from earthquakes, typhoons, tsunamis, ships, etc. The bearing capacity and vibration generated by these loads will directly affect the strength, life and movement characteristics of the platform and jacket structure, and even cause the p...

Problems solved by technology

Regular testing (especially underwater testing) is difficult and costly, with long cycle intervals and limited coverage, and most of the testing methods used are visual, supplemented by some non-destructive testing techniques; calculation and evaluation are carried out using computer software Modeling operation is a theoretical method, and the authenticity and rationality of the data used in modeling (often the most difficult to clarify) directly affects the evaluation results

The two measures are different, and their combination can only reflect the structural status of the platform to a certain extent.
