An arctic drilling barge to perform offshore activities in the shallow water, fast ice regions of the arctic seas. Optimal ice interaction is obtained by shaping the hull of the barge in the form of an upright frustum. Ice which does adhere to the barge is detached and melted by circulating fluid through a plurality of interior hull compartments next to the hull sidewalls of the barge.

Arctic drilling base

A bottom-supported vessel from which subaqueous operations may be performed. The vessel includes a platform and a mat, both of which are configured to permit the platform to nest within the mat while the vessel is floating. The mat is submersible and is adapted to be buried into the soil beneath the ocean floor to provide support for the platform. Legs extend from the mat to the platform and support the platform when the mat is buried. A method of placing a bottom-supported vessel in position for performing subaqueous operations.

Bottom-supported vessel for performing subaqueous operations and method

An improved platform for performing subaqueous operations in ice conditions. A substructure on the platform supports the equipment for performing the subaqueous operation and straddles an aperture through the platform. Means are secured to the underside of the substructure for presenting a relatively low coefficient of friction or low lateral resistance between the underside of the substructure and the face of the platform. Locomotion means are associated with substructure for moving the substructure laterally over the face of the platform relative to the aperture whereby the equipment for performing the subaqueous operations may remain over the wellhead in spite of certain magnitudes of lateral movement of the platform responsive to the ice conditions.
