Much exploration drilling is done in subarctic waters around the world, and this will be important in the future. Special demands will be made on the drilling structures to enable them to withstand collisions with drifting ice. A Newfoundland Certificate of Fitness, for example, says a vessel must be able to tolerate collision with the largest iceberg that can be undetectable by radar, with out the danger of platform collapse. The iceberg in this case is defined as having a weight of 5000 tons and a drifting velocity of 2 meters/second. Devices to prevent ice damage to the trusses of semisubmersibles are discussed.
