The Hibernia platform is uniquely designed to resist the impact of sea ice and icebergs. It can withstand the impact of a one-million tonne iceberg with no damage. It can withstand contact with a six million tonne iceberg, estimated to be the largest that can drift into that water depth and only expected once in 10,000 years, with repairable damage. Because the Hibernia platform is located in relatively shallow water - just 80 metres deep - the odds of a large iceberg ever hitting the platform are extremely low. And those odds are lessened considerably by Hibernia’s aggressive Ice Management Strategy, a combination of science, technology, teamwork and old-fashioned seafaring skill. Information about approaching icebergs is gathered through a variety of means: the International Ice Patrol of the US Coast Guard and the Canadian Ice Service of Environment Canada both provide airborne surveillance briefings;data is gathered by satellite and radar technology, as well as Hibernia’s own state-of-the-art platform radar system, which can identify approaching icebergs up to 18 nautical miles away;helicopters use radio signals to precisely pinpoint an iceberg’s position;platform support vessels are equipped with technology that allows them to collect ocean current information as they steam toward the iceberg and transmit it back to St. John’s via satellite;using side scan sonar, the vessels will go alongside the iceberg and record a detailed profile to measure its draught.
