| Abstract | This paper examines the interaction of pack ice with a Floating Production Storage and Offloading unit (FPSO). The vessel maintains position using a thruster-assisted turret mooring. An ice dynamics model is used to conduct numerical simulations of the interaction of the ice cover with the vessel. The model is based on solving equations describing the conservation of mass and linear momentum together with a failure criterion for the ice cover. The vessel is modelled as a three degrees-of-freedom rigid body. The results give evolution of the stresses and deformation of the ice cover, ice forces, and offsets of the vessel. Ice conditions and FPSO characteristics typical for the Grand Banks were used in the simulations. The results show a strong dependence of ice forces and vessel offsets on ice concentration. The roles of ice floe size and ice thickness were less significant. The conclusions indicate that for the ice conditions considered, vessel offsets would fall well within the operating capabilities of a typical Grand Banks FPSO. |
