The arctic is re-emerging as a frontier for oil and gas developments. High gas prices offer greater incentives than ever for development of stranded fields, perhaps even in ice-bound regions of the Beaufort, Chukchi and Barents Seas.rnThis paper will consider technological solutions associated with the use of fixed offshore caissons for the support gas development concepts and the storage of liquefied natural gas (LNG) prior to export by ship to international markets. The technology is an adaptation of work undertaken in more temperate regions where offshore LNG solutions in relatively shallow water (< 30 m water depth) have been evaluated and constructed.rnSince offshore gravity substructures will be critical building blocks to sub-Arctic and Arctic field gas developments, a number of field development scenarios will be evaluated for Chukchi and Beaufort conditions which incorporate gravity-based extraction and storage facilities. Cost and schedule estimates for a typical development will be developed to provide inputs to the assessment of viability of the scenarios.
