Now, when we think about what decommissioning is, it must address the reasonable risks, and that is all. The reasonable risks include—look, what's the balance in terms of health and safety versus environmental performance if you have to send divers down to remove things that were never intended to be deconstructed or removed. It's only more recently that we've actually designed structures and buildings, for example, with the idea that they will in fact one day be deconstructed. Many things built in the past were not designed in that way, and it's very dangerous to try to remove them, particularly if you're talking about places where there are significant currents and movements on the seafloor. So decommissioning should be limited to what is required to meet environmental objectives while taking care of the health and safety of the workers involved, and make sure that what's left behind is recorded so that we know what's left behind. But that should be the limit of it.
