PSA carries out safety check on 'COSLInnovator'
From 10th to 13th June 2014, the Petroleum Safety Authority (PAS) Norway carried out an audit of Statoil's use of managed pressure drilling using ‘COSL Innovator’ on the Troll field. The objective of the activity was to audit that Statoil, the service providers, drilling contractor and other stakeholders, were planning, performing, and garnering experience from, the MPD operations in accordance with their own requirements, regulatory provisions and defined standards. The audit identified one non-conformity in connection with a safety-critical barrier element.
