The offshore platform structure is major infrastructure for the development of offshore petroleum resources and a base for offshore production operations and life. The environment of the offshore platform structure is very complicated and bad, and under environmental influence, the resistance of the offshore platform structure may below. The failure of the offshore platform structure not only causes direct major economic losses and casualties, but also may cause serious environmental pollution and social and political impacts. This paper describes the establishment and modification of a real-time calculation model of the offshore platform structure, determines the real-time environmental load of the system based on marine environment monitoring, proposes a real-time safety assessment method of the offshore platform structure, and develops a Windows application using the Delphi development tool. The system was commissioned twice in the Bohai JZ20-2MUO platform during the winter of 1998–99 and 1999–2000 and the security status of the JZ20-2MUO platform in the winter was monitored in real time.
