ABSTRACT:
Method and apparatus for building a thickened ice mass, such as a grounded ice island, at a cold offshore location, in which water is pumped through a fluid flow conduit and discharged from a rotating swing arm section of the conduit onto selected areas of a natural ice sheet to form circular and/or annular thickened ice bodies. The fluid flow conduit includes a first water supply line disposed in the water body between the ice sheet and the marine bottom, and, if required, a second water supply line which is installed along the top surface of the ice island after the grounding of the ice body forces abandonment of the first water supply line.
