STAVANGER, Norway -- TDW Offshore Services has designed and delivered a customized pipeline repair solution for StatoilHydro's Kvitebjørn field.
The field was shut down in August 2008 when a gas leak was discovered approximately 10 km (6.2 mi) from the platform. The pipeline was dragged out of position and damaged by a passing ship's anchor. StatoilHydro awarded TDW Offshore Services a contract to assess the situation, and to develop a solution to repair the subsea pipeline between the platform and the Kollsnes processing plant near Bergen.
The company carried out extensive testing, including an onshore installation of a special subsea clamp system onto a mock-up of the affected portion of the Kvitebjørn pipeline. The purpose of the clamp was to secure integrity for the pipe connector in the event that it was not possible to obtain adequate holding power with the primary solution, the company says.
