Fleet-wide ponds decommissioning: Learning from Experience

A major UK decommissioning operator faced losing 25 years of ponds decommissioning knowledge. We captured Learning from Experience across nine stations in a 250-page report, delivered two days ahead of programme and under budget.

Problem

A major UK decommissioning operator faced losing 25 years of ponds decommissioning knowledge. Experienced personnel were retiring mid-programme and there had been no fleet-wide capture of Learning from Experience, just as the next generation of plants prepared to come offline.

Intervention

We mobilised a team specialising in programme management, engineering and leadership to assess the position across nine stations, interviewing personnel with ponds decommissioning experience across the fleet and deep-diving historical drawings, photographs and reports.

Outcomes

  • A 250-page report citing each station, fleet-wide challenges, technologies deployed and top lessons learned
  • A complete register of technologies by station, decommissioning phase and supplier, fully referenced to source documentation
  • Delivered two days ahead of programme and under budget, with all work accepted: no concessions, compensation events or variations
  • The report now stands as the body of knowledge informing future pond decommissioning across the fleet and at future sites
