Task force members

As decommissioning activity increases in the mature UKCS, the Decommissioning Task Force’s (DTF) objective is to support industry in minimising the cost of decommissioning with a focus on delivering what would otherwise not be delivered by industry. In doing so the DTF supports significantly reducing the total decommissioning price tag of £59.7 billion, to a target of less than £39 billion.
