EXPERIENCE IN ICE PLATFORM CONSTRUCTION FOR ARCTIC DRILLING

The construction of sea-ice platforms averaging 5 meters (16 feet) thick at the centre has permitted successful offshore drilling in the Arctic Archipelago at a time when ice conditions prevent the use of conventional offshore rigs. The development of fixed, high capacity flooding stations, capable of operating at temperatures of -50 deg. C or lower, and the use of free surface flooding from these stations has contributed to average ice buildup rates of 10 cm/day (4 in/day) during the months of December and January. A review of our experience with electric submersible pumps and a discussion of the factors affecting the ice growth rate and the apparent superiority of the free-flood method over spraying or sprinkling in the construction of large platforms is presented. /Author/
