This paper presents the details of the ice conditions surrounding offshore caisson structures at different sites in the Canadian Beaufort Sea. This information is required as input for the design of suitable emergency evacuation systems from Beaufort Sea production structures. Reports from ice observers were reviewed and “time-lines” of the ice conditions were generated. There was a wide range of ice regimes at the sites. In some cases, large grounded rubble fields formed and were stable throughout the winter. At other sites, there was moving pack ice throughout the winter. Typically there were about 100 days of open water at each site. For the remainder of the year, ice surrounded the structure. These conditions must be taken into account in the design of suitable emergency evacuation systems. NRC publication: Yes
