The exploration/production operator making all major decisions related to petroleum activities (i.e. selection of rig, well design and selection of service companies) should be made responsible for demonstrating to the regulator that drilling operations can be conducted safely. Where the drilling contractor owns the rig and conducts the day-to-day management of safety on the rig, this duty can be described in a rig specific Safety Case that is owned by the drilling contractor. This rig specific Safety Case does not have to be submitted for every well/well operation.
