Dynamic Response Analysis and Positioning Performance Evaluation of an Arctic Floating Platform Based on the Mooring-Assisted Dynamic Positioning System

The Arctic region is rich in oil and gas resources, but exploitation of resources there always facing great challenge. Floating offshore platform considered as a practical choice for exploration the deep water regions. One key technologies positioning system design under harsh arctic sea loads. In this paper, comprehensive investigated. A coupled numerical model composed mooring-assisted dynamic Kulluk established. 16 different combination forms are selected capability evaluated by analyzing motion response environmental loads, including wave, level ice, broken ice floes. Wave load calculated using potential flow theory. Computation compared with finite element method (FEM) discrete (DEM). analysis mooring carried out slender method. control adopts proportional-integral-derivative (PID) methodology. It found that better can reduce offset more than 50%, surge, sway yaw motion. results study will provide good reference an floating production platform.
