When an investigation has been completed and corrective action is necessary, the PSA (Norway) approach is to make the operator take ownership of the problem. The operator is directed to develop solutions and implementation schedules that are acceptable to the regulator. See the PSA directive to Statoil below following the investigation of the Gullfaks B gas release.
In contrast, there is a tendency in the US for the regulator to take ownership of the problem and thus assume responsibility for developing solutions. The regulator dictates these solutions to the operator (and perhaps the entire industry), sometimes without sufficient discussion or analysis. Of course, US regulators may not have a choice in the matter as the political system often demands that the regulator take action, perhaps before the investigation is even completed (or started!).
Which approach presents the greater opportunity for success? Most regulators would say the former, and that was the consensus view at the International Regulators’ Offshore Safety Conference in Vancouver.
