Fire and blast in 1st edition of api rp-2top standard

The main objective of this paper is to present and discuss the Fire and Blast design methodology for offshoreplatform topsides with reference to the API RP-2TOP Standard. The first edition of the API RP-2TOPstandard has been published recently and consists most up to date provisions for the tospides design for fireand blast loads. The paper focuses on the key aspects of the topsides design of offshore platforms for fireand blast loading as addressed in the API RP-2TOP standard, summarizes the design recipe and highlightsthe differences between the API RP-2TOP and corresponding API RP-2FB provisions. A risk matrix isprovided as a means to determine the acceptability of the risks from accidental events of fire and blast andcan primarily be used as a means of screening low-risk events that do not need further investigation. Inaddition, a detailed and structured methodology is provided for structural assessment from fire and blastevents. The fire and blast scenarios should be developed as part of the process hazard analysis.
