Calculation of Towing Resistance for Offshore Towing Operation of Drilling Platform Considering Multi-Factor Constraints

In order to improve the calculation accuracy of the towing resistance of the offshore towing operation of the drilling platform, it provides a reference for the reasonable matching of the tugboats that meet the requirements. Based on the “Guide to Marine Towing” and the theory of fluid mechanics, comprehensively considering the characteristics of the navigation environment of marine towing operations, and introducing various additional resistance factors such as towline resistance, rough sea resistance, and fouling resistance, a drilling well considering multi-factor constraints is proposed. Calculation method of towing resistance for platform offshore towing operation. The method is applied to the calculation of the drag force of the offshore towing operation of “A drilling platform” in Shengli Oilfield, and the results show that the calculation results of the method proposed in this paper are closer to the actual situation compared with the calculation results of the guide. In order to be scientific and reasonable, the accuracy of the calculation method in this paper is verified.
