ABERDEEN, UKPlant 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.

At the same time, it delivers cost and time savings...”
