ABSTRACT:
A marine structure comprising a cellular caisson which forms a stable platform for carrying out a variety of offshore operations in the arctic and sub-arctic regions is provided. The structure may be grounded on reasonably level sea bottom with a minimum of sea bed preparation in shallow water or mounted upon a previously prepared berm. Resistance to local ice forces is provided by the hexagonal cellular arrangement of the perimeter and interior walls which make up the cellular caisson. Global foundation resistance is obtained by introducing a suitable quantity of ballast into the structure. The design allows clusters of two or more structures to be grouped together to augment the offshore installation and to permit the offshore installation to be developed in stages at the site.
