Abstract: The potential use of energy from a wind farm to reduce on-platform power generation for offshore Newfoundland is considered as part of a research study. The region is subject to iceberg and sea ice incursions in addition to high sea states, with water depths ranging from less than 100 to more than 1000 m. For most of this region, bottom founded platforms are not economical. A variety of Floating Offshore Wind Turbine (FOWT) platform designs have been installed worldwide, or are under consideration, but not in regions with ice. It is of interest whether a wind farm can be installed and operated at a reasonable cost in this environment while providing the required power with sufficient reliability. This paper presents an analysis of 50-year iceberg impact parameters for four platforms: a spar, a barge, a semisubmersible and a Tension Leg Platform (TLP). The potential advantages and disadvantages of the different designs with respect to ice actions are investigated.
