Study On The Maintenance And Modification Of FPSO In Engineering Practice

At present, China offshore oil and gas exploration is mainly concentrated inBohai, the Yellow Sea, East China Sea and the northern continental shelf of SouthChina Sea, only Bohai area has proven reserves of more than million tons of oil isseven. FPSO mined from the seabed oil, processing and offloading, and the offshoreoil platform to provide power, heat, fire protection and control, so that we say FPSO isthe core equipment in the oilfield is playing more and more important role. But withthe development of the mining depth, many serving FPSO is close to life or reach thedesign life. And with the typhoon, the sea ice weather frequently visit, many FPSOare experiencing extreme environmental load and the huge production load, or evenfacing the risk of extended service. So FPSO using structural finite element directcalculation method of assessment, effective accounting of the effects of the harshconditions on the assessment of the FPSO, beyond the design service life is still issafe and reliable service, and with the repair before the inspection check out hiddenpoints to FPSO, a comprehensive transformation of repair.Relevant examples based on FPSO maintenance and modification after thestrength finite element structural safety assessment of FPSO, then to FPSO in order toadapt to the repair and reconstruction of the maritime safety production and service,and comprehensive interpretation of the link specification methods and keytechnology, FPSO close-up survey, nondestructive detection and thickness measuringrange to determine the relevant steps are explained, the study in which detectionmethod and detection of the content and the understanding of the specification toensure that the FPSO repair transformation before the inspection accuracy. Finally,according to the process during FPSO maintenance and modification are often used todescribe the structural features and repair, and have a definite object in view ofinterpretation of FPSO cautions and operation process. For the future FPSOassessment and reconstruction project construction provides a reference example andtechnical support.
