ABERDEEN, UK – Plant Integrity Management (PIM) says that a review of inspection procedures has improved valve operations at various field complexes in the Danish North Sea.
The company won a contract in 2014 to provide a risk-based inspection (RBI) review of pressure safety valve recertification (PSV) results at 11 platforms, including on the Tyraand Gorm fields, using PIM’s proprietary PSV software.
The RBI covered 2,249 valves comprising 761 hydrocarbon valves and 1,488 non-hydrocarbon valves.
Prior to an initial PSV consequence assessment in 2013, each valve had been inspected every 24 months. The consequence assessment resulted in the average inspection interval extending out to 34 months.
The current RBI review has delivered further improvements with the average inspection interval now at almost 36 months.
Colin Shields, valve specialist at PIM, said: “Extending the inspection interval following a comprehensive RBI gives the client confidence that their pressure safety valves are being correctly managed while ensuring the safe and effective operating of their asset. At the same time, it delivers cost and time savings...”
