World’s Longest Subsea Pipeline

By two thousand and eight, Norway will be connected to the United Kingdom via a 1200 km super pipeline—the longest subsea pipeline in the world. But this connection is only a part of an enormous plan to tap into Norway’s second largest gas deposit, capable of providing 20% of the UK’s gas needs for decades to come. Located 3 km below the ocean’s surface and 120 km offshore, the deposit is beyond the reach of humans and all of the construction has to be completed by robots working against strong underwater currents, sub-zero temperatures and extreme wind and wave conditions. When tapped, the gas will be transported to one of the largest automated gas processing plants to prepare it for shipment to U.K. Each phase will put ingenuity and engineering to the ultimate test.
