Optimizing the design of offshore structures to withstand ice loads is a challenging task and various efforts are under way to develop robust concepts with acceptable structural safety. To ameliorate the deficiencies of structural design, as well as to reduce the costs of such Arctic offshore field developments, ice management operations may be considered to reduce the ice severity. Ice management in sea ice will typically involve use of 1 to 4 icebreakers depending on the operating environment. The ice management fleet is aimed at protecting the offshore installation by breaking the incoming ice into smaller pieces and by reducing the confinement in the ice cover. Failure of such a marine operation in the demanding Arctic environment can threaten the integrity of the offshore platforms or drilling units, e.g. by increasing the chances of failure of mooring lines in the occurrence of extreme events.
