Licensees should be subject to an express obligation to inform regulators of problems which arise in the course of installing barriers, even if they consider that well integrity is not thereby compromised. The information should be provided by way of special report, rather than included in a standard reporting document (such as a DDR). The information provided should include risk assessment details.

The successful installation of every barrier should be the subject of written verification within and between licensees and rig operators; and should be the subject of explicit reporting to the relevant regulator(s).
