N2 - The technology of PSA(probabilistic safety assessment) based on fracture mechanics has been applied on the engineering field. However there're few application on the port machines still with some problems. A comprehensive discuss on PSA method was presented in this paper. Firstly, the experiment of the fracture mechanics parameters of Q345 steel used on the port machine's structures was made to provide the parameters for PSA. Secondly, probabilistic analysis with the series of the Q345 steel's FAC(Failure Assessment Curve) provides the PSA criterion. By using stress analysis, defect detection and material properties, the structures safety of a RMG(Rail Mounted Gantry) of one port in service were assessed, the result show that the key points of the crane are safe in one point service. The technology presented in this paper will be significant for the operation and management of the port equipment.
