Designing offshore structures for iceberg loads in arctic and subarctic regions presents unique challenges. The ISO 19906 standard provides guidance for the calculation of design ice loads using both deterministic and probabilistic approaches. C-CORE has developed and applied a software package, the Iceberg Load Software, for determining global and local design loads associated with iceberg impacts. Using this software, a number of issues related to design global and local iceberg impact loads for fixed structures are examined. This paper highlights these issues, including iceberg and structure shape, global ice crushing pressure, low iceberg impact frequency, ice management influences and variation in design loads and moments with impact location on structure.
