Present paper is concerned with the system reliability analysis of a floating offshore structure using the developed algorithm called’ Extended Incremental Load Method’, which is an extended approach of the conventional incremental load method, and has been developed in order to extend its applicability to the system reliability analysis of a structure under multi-loadings and to more realistically take into account the post-failure component behaviour.

The modified equation of safety margin is proposed to use the existing strength formula for principle components of a floating offshore structure, in which the concept of the First-Order Second Moment Method is used.

The application to a simple frame structure and a Tension Leg Platform have been carried out and their results show the validity of the proposed approach.
