해양플랫폼의 거동 모니터링 시스템 분석

Abstract

It is important to measure and analyze offshore platform motion data for the safety of offshore platforms that are installed in an extreme environmental conditions. Especially, in the Gulf of Mexico, because of the hurricane and loop current that has been strengthened due to changes in the ocean environment, a monitoring system is necessary to measure the offshore platform motion data in real time, as well as simultaneously analyze it for safe operation and accident prevention. In order to develop such a monitoring system, it is extremely critical to obtain accurate data. However, since data measured in real time is not suitable for analysis due to quality problems, the data must be processed. The problem is that the processed data differs depending on the processing methods being employed, and results in entirely different analysis results. Incorrect results can mislead the current state of the offshore platform causing missed maintenance periods or, in the worst case, major accidents. Therefore, verifying both the adequacy of the methods used to process the data and the accuracy of the results is most vital. In this paper, improving reliability of the monitoring system that can measure offshore platform motion data and analyze data in real time, the validity of the method used in measurement data processing and the accuracy of the processed data were verified.
