Pigging Campaign Management

Samphire Subsea Case Study

After 15 years in operation, in order to support life extension actual quantified data was required for a production pipeline system. The pipeline system was configured as a loop with flexible steep wave risers. The topsides equipment although partially in place had never been used since the original asset commissioning phase.

Samphire was engaged to manage the engineering and execution of the inspection pigging campaign. The plan was to fully assess the existing pigging equipment and execute the campaign from topsides.

With a target of execution aligned at the end of the asset shutdown, time was of the essence and contractor selection / pigging strategy had to be pulled together quickly. Since the lines had never been pigged before, a low risk strategy was developed to manage the key areas; debris, general cleaning and pigging through flexibles.

Samphire worked through the topsides equipment checks and readiness, contractor selection for cleaning tools and inspection.

Work execution was managed through tool development and testing, onshore desk reviews and the execution of the offshore campaign.

The campaign was successfully delivered on time, in budget and incident free.
