STAVANGER, Norway – TDW Offshore Services has signed a frame agreement with Centrica Storage Ltd (CSL).

This involves providingpipeline isolation services with the SmartPlug tool, which allows pressure in an active pipeline to be safely isolated and production to continue while maintenance is performed.

TDW has worked on numerous pipeline isolation operations forCSL’s Rough gas storage facilities. Recently, CSL isolated the main sealine connecting the offshore 47/3B platform with its Easington gas terminal on England’s eastern coast, with a SmartPlug system installed in the platform riser.

“This allowed change-out of the platform emergency shutdown valve without the requirement to vent down the 30-km (18.6-mi) long pipeline, minimizing the greenhouse gas emissions associated with natural gas venting,” said Paul Hardy, integrity engineer for CSL.

“In addition, CSL prefers to keep the pipeline at pressure, thereby reducing the number of pressure cycles and minimizing fatigue life usage. Isolating the pipeline using the SmartPlug achieves this objective.”
