Readiness Review in advance of restart of Crane Refuel Operations

Executive summary

Purpose of Intervention

This intervention at the Devonport Royal Dockyard (DRDL) licensed site was undertaken in order to provide assurance to ONR that DRDL had enhanced its arrangements for the safe control and operation of refuel related crane activities prior to resumption of these activities.

Interventions Carried Out by ONR

The intervention consisted of an inspection of DRDL’s readiness to resume Refuel related crane activities, seeking to confirm that the licensee has made the necessary improvements to demonstrate that adequate arrangements are in place for the safe control of crane operations. 

The readiness inspection was undertaken by the ONR Nominated Site Inspector accompanied by a specialist inspector, and involved examination of relevant licensee documentation, targeted discussions with relevant members of the licensee’s staff and a walkdown of the relevant facilities. The scope of inspection was derived from relevant ONR Technical Inspection Guides (NS-INSP-GD-026 Revision 3, NS-INSP-GD-028 Revision 5) and from the relevant Approved Code of Practice for the Lifting Operations and Lifting Equipment Regulations (L113 (Second edition) Published 2014).

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A

Key Findings, Inspector's Opinions and Reasons for Judgements Made

The ONR inspection team undertook a deep slice sample into the enhanced arrangements that will be implemented by DRDL in relation to the planning, organisation, control and supervision of crane activities associated with refuel activities. The inspection team concluded that DRDL has made the necessary enhancements to demonstrate that adequate arrangements are in place for the safe control of refuel related crane operations.

Conclusion of Intervention

On the basis of the information provided and evidence obtained during this intervention, I concluded that the licensee has made the necessary enhancements to demonstrate that adequate arrangements are in place for the safe control of refuel related crane operations. There are no regulatory issues to address before site releases their own internal Hold Points for the restart of refuel related crane activities.
