Devonport Royal Dockyard Limited - Readiness Review for Planned EIMT/repair in advance of Restart of 9 Dock RAH 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 the planned EIMT/repair activities prior to it undertaking 9 Dock Reactor Access House crane operations.

Interventions Carried Out by ONR

The intervention consisted of an inspection of DRDL's readiness to commence planned EIMT/repair activities prior resuming 9 Dock Reactor Access House crane operations. The intervention was undertaken by conducting an inspection of the licensee's compliance with Licence Condition 28 (Examination, inspection, maintenance and testing (EIMT)), focusing on the enhanced arrangements that have been implemented following the serving of two Improvement Notices on 1 August 2017.

The readiness inspection was undertaken by an ONR Principal Site Inspector, and involved examination of relevant licensee documentation and targeted discussions with relevant members of the licensee's staff. 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 compliance arrangements for Licence Condition 28 in relation to the 9 Dock Reactor Access House crane were found on inspection to comply with legal duties and relevant good practice was generally met.

No shortfalls were identified and in my opinion, DRDL has made the necessary improvements to demonstrate that the planned EIMT repair activities prior to undertaking 9 Dock Reactor Access House crane operations comply with legal requirements.

In my opinion there is an adequately systematic internal Hold Point control process in place to allow DRDL to release defined internal Hold Points prior to resumption of Reactor Access House 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 improvements to demonstrate that the planned EIMT / repair activities prior to undertaking 9 Dock Reactor Access House crane operations comply with legal requirements.

There are no regulatory issues to address before site releases their own internal Hold Points for the planned EIMT/repair activities and subsequent 9 Dock Reactor Access House crane operations.
