Analysis of Capability Requirement of Dynamic Positioning System for Cargo Transfer Vessel at Sea

Abstract

In response to the development of deep-sea oil and gas resources, which require a high degree of cooperation by crude oil transportation equipment, a new type of ship known as the cargo transfer vessel (CTV) has been developed. To provide a theoretical reference for the design and equipment of the CTV’s dynamic positioning system, in this paper, we take the new deepwater CTV as the study object and theoretically and numerically analyze its operation, wind load, current load, wave load, and navigational resistance in a range of Brazilian sea conditions with respect to its positioning and towing modes. We confirm that our proposed method can successfully calculate the total environmental load of the CTV and that the CTV is able to operate normally under the designed sea conditions.
