Abstract: There is a trend towards reducing the emission of greenhouse gases from offshore hydrocarbon production off the east coast of Canada. One of the proposed solutions is the electrification of the production facilities using floating offshore wind farms. The design and operation of floating offshore wind turbines in regions with icebergs and sea ice introduces new challenges related to the potential impacts with ice features. In addition to withstanding environmental driving forces such as those from wind, waves and currents, the platforms must be designed to withstand global and local actions from icebergs and sea ice. This paper presents the results of a preliminary regional analysis of iceberg risk to four unique floating offshore wind turbine structures. Iceberg and metocean characteristics were extracted from the Nalcor Exploration Strategy System (NESS), and the Iceberg Load SoftwareTM (ILSTM) was used to assess 50-year global and local iceberg actions. Advantages and disadvantages of the structures are discussed. The work is part of a larger study investigating the effects of icebergs, sea ice and icing on floating offshore wind turbines.
