FIXED OFFSHORE PLATFORMS IN THE ARCTIC OCEAN

Due to the current surge of interest in development of hydrocarbon reserves on the North Slope of Alaska, and the McKenzie Delta and Arctic Islands area of Canada, it is evident that a need exists, and will become more pressing in future, for fixed marine structures to support drilling, production, and product transfer operations. In the event that over-land Arctic pipelines will be restricted by government agencies, berthing facilities will also be required to service submarine or surface tankers. Structural concepts for ice-force resistant platforms which are economically successful will be those which may be fabricated in whole or in major sub-assemblies in environments hospitable to outdoor, year round construction, and then transported to, and erected on, the desired location with a minimum of on-site labor and equipment. Structurally successful concepts will be those which incorporated geometries taking advantage of minimum failure modes in the forcing ice, and which allow for a range of ocean floor conditions and water depths. Several concepts for fixed platforms are presented which fulfill the above criteria; one of which was presented to an arctic petroleum producer while the author was employed by a major offshore contractor.
