| Abstract | This paper provides an illustration of how to assess acceptable ice conditions for vessel stationkeeping in pack ice. Numerical simulations are used to examine pack ice interaction with a moored/thruster-assisted vessel, including maximum forces and vessel responses. The ice dynamics model utilized for this purpose is based on solving the equations of momentum and a failure criterion. The station-keeping vessel is modeled as a rigid body with three degrees-of-freedom: surge, sway and yaw. Here, ice conditions and vessel characteristics are chosen within a range of values that are relevant to operations on the Grand Banks during seasonal pack ice intrusions. The simulations examine the influence of several variables, including ice coverage, ice thickness, velocity, floe size, peak forces and vessel offsets. The influence of these variables on peak ice forces and key vessel responses is evaluated from an operating envelope point of view. |
