A multiyear program was initiated by ARCO Alaska, Inc. to assess the operational feasibility of drilling operations year-round in the ice-covered waters of the Bering, Chukchi, and Beaufort Seas. ARCO Alaska, Inc. is considering several alternative concepts for year-round drilling in the Bering Sea. One such concept, the Ice-Resistant Semisubmersible Drilling Unit, is a design concept of Mitsui Engineering and Shipbuilding Company. The design is intended to operate in broken, continuous, and ridged sea ice, and withstand severe open water sea conditions. The requirement to operate in two dissimilar environments results in a unit that is somewhat unusual when compared to typical semisubmersible drilling units.
