PROJECT DESCRIPTION

  • The Schiehallion, Loyal and Foinaven fields are located approximately 150 km west of the Shetland Islands in quadrant 204 of the UKCS. The water depth is approximately 400m. Schiehallion, Loyal and Foinaven together with the Clair field are situated in the area generally termed the West of Shetland (WoS).
  • Following inspection of a Flowline Termination Assembly on the East Water Injection flowline, a pinhole leak was identified in the pipeline. The pinhole is thought to be at the weld between the FTA 10” destec flange and the 10” pipeline. The flowline was isolated and taken out of service until the situation could be remedied.
  • IK-Norway AS was awarded a contract for designing and manufacturing a sealing solution for this leakage. The sealing solution is requested to be an ROV Operated Patch Clamp, to be clamped outside the pipe and comprises an elastomeric seal that is engaged by pressure.
