Towing resistance calculation of the cylindrical drilling platform

Towing the large-scale drilling platform without self-propulsion is difficult. Towing resistance calculation is necessary for safe pilotage. The tug power decision and the fleet arrangement should be confirmed according to the features and performance of towed vessel, water flow, air flow and other meteorological factors in towing route. The resistance calculations of towed vessel and tugboats are carried out. Whether it is suitable to be towed by the fleet will be verified in accordance with the calculations of the hauling power of tugboats. In this paper, the towing resistance of the cylindrical ultra-deep drilling platform without self-propulsion capability is studied, which could provide reference for other cylindrical structures on the implementation of towing plans.
