In this paper, following a brief review of offshore system (application) safety analysis, offshore software safety analysis is introduced. It is followed by a study of combining offshore system safety analysis with software safety analysis. The typical standards for the development of safety-critical systems in several industrial sectors are discussed with particular reference to formal methods. A generic offshore software safety analysis framework is proposed with discussions. Formal methods for producing safety requirements specifications are then discussed. A case study is used to demonstrate safety requirements modelling for safety-critical software development. Finally recommendations for further development in offshore software safety analysis are given. - Reproduced aSafety measures aPetroleum industry aDisaster Prevention and Management
