Independent Review Group (IRG)
The Independent Review Group provides peer review of the quality of the studies carried out. The final responsibility for the contents of the reports however rests with their authors and Shell, and the IRG does not necessarily support or endorse every statement in the individual reports.
The specification of the work for the various studies and the selection of contractors to undertake the work lay with Shell, but the IRG was able to suggest additional topics for investigation.
The IRG will not comment on the final decommissioning options selected. Its role is to ensure that an appropriate range of options has been examined in sufficient depth, so that the information available is adequate for a rational decision to be reached by Shell.
The independence of the IRG is ensured by the IRG, or any of its members, having the right to publish its/their findings, including any objections.
