PSA Releases New Version of Barrier Memorandum
Barriers have been part of the Norwegian Petroleum Safety Authority’s (PSA) regulations since 2002, but the industry’s implementation of the requirements has taken time.
The PSA has been monitoring the industry’s work on barrier management for a number of years. The barrier memorandum, which explains the regulatory requirements and describes good barrier management, was first published in 2011 and then updated in 2013. The PSA’s barrier memorandum has now been updated. The new version includes a clearer explanation of what barriers are and expounds on the interaction between technical, organizational, and operational barrier elements.
Gerhard Ersdal, an engineer with the PSA, explained the reason for the update. “Audits and investigations have shown that the companies have largely not identified the human contribution to barriers, meaning who does what, with which equipment, in order for a barrier to realize its function. Mainly, they have only defined requirements for the technical barrier elements,” he said. “Audits and investigations have also shown that there is great variation in what is considered a barrier. A couple of years ago, the PSA initiated a project to promote more consistent barrier management, including also the human components.”
