Abstract

Offshore platform may face fire attack during its service time for oil and gas drilling process. As both the yield strength and the elastic modulus are severely deteriorated at elevated temperature, the offshore platform has a loss in its load-carrying capacity or even loses such capacity. Based on heat transfer theory and finite element simulation, this study analyzed the fire resistance of welded tubular joints in the offshore platform. The failure process of the tubular joints in fire condition is investigated. The emphasis is focused on the investigation on improving the critical temperature of a tubular joint in fire condition by locally increasing the wall thickness of the chord. The results indicate that increasing the wall thickness of the chord locally can improve such critical temperature efficiently for a tubular joint, and thus, it is useful to increase the fire endurance time for an offshore platform in fire condition.
