In order to solve the optimal selection problem of the design projects of swing devices in crown-block heave compensation system for offshore drilling, the optimal selection method of the design projects of swing devices in crownblock heave compensation system for offshore drilling was studied by integrating analytic hierarchy process, variation coefficient method, grey relational analysis and TOPSIS. The subjective weights of evaluation indexes was figured out by AHP and the objective weights of evaluation indexes was figured out by variation coefficient method. Then the synthetical weights model was established based on relative entropy theory. Furthermore, the optimal selection method of the design projects of swing devices in crown-block heave compensation system for offshore drilling was established based on relative entropy weighted-grey TOPSIS. The method is easy to use and can solve the optimal selection problem of the design projects of swing devices in crown-block heave compensation system for offshore drilling.
