RR58 - Decommissioning offshore concrete platforms

Covers two recently completed studies that assess the risks to people and the environment from decommissioning concrete platforms. The feasibility of refloating and disposing of the concrete bases of very large platforms of the type found offshore in northern Europe is assessed. Examines possible options for removal and demolition, considering the design of the structures and their current conditions and taking into account of the present state of engineering knowledge and any likely future developments. Both studies indicate that risks from removal could be very high and refloating may not be possible for some older platforms. For all options, risks of injury to personnel from subsea work, underwater cutting or structural collapse from overloading could exceed the normally accepted risk criteria unless these operations can be very carefully controlled.
