Nowadays, many existing offshore platforms which exceed or approach their design life are still carrying on with producing in the ice zone, so the safety operation is the key issues. In winter, sea ice is the controlling load. Full scale measurement for many years shows the design of some ice-resistant platforms is not so sophisticated, the most significant is that ice induced vibration is the main which has caused harmful accidents in Liaodong bay of Bohai. In order to ensure security operation, structural safety ensuring in winter becomes key problems. In this paper, sea ice management system oriented structural safety ensuring of oil or gas ice-resistant platforms in ice zone is presented. By combining structural monitoring, safety assessment and risk forecast, the system belays and incorporates high safety, cost-benefit, alternative emergency measures.
