Application of Fiber Bragg Grating Sensing Technology in Key Equipment Monitoring of Offshore Platform

Due to the special marine environment, it is difficult for the traditional electronic sensors to play a long-term real-time on-line monitoring role in the key equipment of offshore platforms under the environment of high humidity, high salt, high pressure, corrosion and electromagnetic interference. Based on the principle of fiber grating sensing and material properties, Based on fiber Bragg grating sensing principle and material properties, the fiber grating sensing technology is introduced to monitor the key equipment status of offshore platform in real-time, and the key and possible dangerous position location monitoring and establish the early warning system, which helps on-site staffs to find out the problems of equipment structure in time and take corresponding measures to ensure the safe production operation of the offshore platform. In this paper, combined with the monitoring cases of offshore platforms, such as jacket platform, workover rig derrick, dry-type transformer cabinet, etc. The status monitoring methods, advantages and existing problems of FBG sensing technology in the field of offshore engineering application are discussed, so as to provide basis for the future development of FBG sensing technology in the field of offshore engineering.
