ABSTRACT:
A mobile drilling and production platform for arctic regions in which a hull having a deck forming the production platform is supported on a first set of parallel runners secured to the underside of the hull and extending fore and aft with spaces between the runners. A second set of parallel segmented runners are secured to the underside of the hull and extend perpendicular to the first set of runners, the second set of runners including a plurality of sections positioned in the spaces between the first set of runners. A plurality of rotating ice cutters are mounted on the hull and extend down in front of the ends of each of the runners, the ice cutters cutting channels in the ice in which the runners move and support the hull. One set of runners is vertically movable from the hull relative to the other set of runners whereby the weight of the hull can be transferred from one set of runners to the other to permit movement of the platform along two perpendicular axes or coordinance of motion.
