TDW Offshore Services has successfully designed and delivered a customized pipeline repair solution for StatoilHydro.
TDW Offshore Services was awarded a contract by StatoilHydro to assess the situation, and develop a solution to repair the subsea pipeline. Working in close cooperation with StatoilHydro, TDW Offshore Services set to work. Extensive testing -- including an onshore installation of a special subsea clamp system (Patent Pending) onto a mock-up of the affected portion of the Kvitebjorn pipeline -- was carried out at its base in Stavanger. The purpose of the clamp would be 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 clamp, which is one of the key features of the Kvitebjorn field pipeline repair solution, was specially designed, developed and produced by TDW Offshore Services engineers as part of StatoilHydro's solution for repair of the Kvitebjorn.
The Kvitebjorn field began delivering natural gas on October 1, 2004. Rich gas and condensate (light oil) from Kvitebjorn are piped to Kollsnes near Bergen and Mongstad further north, respectively. Following processing at Kollsnes, the dry gas is piped to continental Europe. The separated NGL is transported by pipeline to the Vestprosess plant at Mongstad for fractionation into propane, butanes and naphtha. Based on current plans, it is expected to recover roughly 55 billion cubic metres of gas and 22 million cubic meters of condensate.
