Devonport - DRDL - Crane Event Follow up Enquiries with Devonport Operations and DRDL Internal Regulator

Executive summary

Purpose of Intervention

This intervention at the Devonport Royal Dockyard (DRDL) licensed site was undertaken to conduct follow up enquiries with Devonport Operations and the 9 Dock management staff. The enquiries were undertaken to establish the facts relating to five recent crane related events.

Interventions Carried Out by ONR

Follow up enquiries were conducted following five reportable events which occurred on the Devonport 9 Dock site. Discussions were held with a number of key stakeholders associated with the events to better understand what happened and the actions DRDL are putting in place to prevent a repeat occurrence.

A meeting was also held with the Head of Nuclear Assurance. The purpose of this meeting was to understand the role that the internal regulator has delivered in response to the crane events.

Conclusion of Intervention

Despite the actions currently being delivered by DRDL, I consider that there are still gaps in DRDL's arrangements. These gaps relate to arrangements for planning, organisation, control and review of work activities on the licensed site.

Further work should be undertaken by DRDL to identify the shortfalls against relevant good practice in these areas to ensure that the necessary improvements are brought about in a prompt manner.
