Combined Operations Notifications

The 2015 Safety Case regulations require that a Combined Operations Notification must be provided to the UK CA.

When combined operations are to be undertaken, that is combined between two units which have Safety Cases, risk assessments must be carried out and bridging documents provided. Typical combined operations are well interventions by semi-submersibles where there is connection by pipeline to a central platform, the provision of accommodation for offshore workers where there is a connection by gangway to a platform and tender operations where a mobile is anchored close to a platform and provides manpower and power and fluid services. And possibly the most common combined operation is the use of jack-ups to drill through platforms constructing new wells and maintaining others.
