AbstractIce accretion on offshore structures is a problem that must be considered by rig designers, rig operators, and regulatory agencies. For ground-based structures, the problem relates to increased cross-sectional area of the support members with a consequent increase in lateral forces generated by wave-structure interactions. For semi-submersible rigs, there is the added concern of increased dead weight due to accreted ice resulting in reduced freeboard or reduced deck load.A computer program called RIGICE was developed in the late 80s to simulate ice accretion on offshore structures (Brown et al. 1988). Since then the code has undergone modifications to some of the algorithms, particularly those dealing with spray generation due to wave-structure impact.
