DRDL - Improvement Notices Close-Out Inspection

Executive summary

Purpose of Intervention

This intervention at the Devonport Royal Dockyard (DRDL) licensed site was undertaken in order to provide confirmation that the contraventions identified in Improvement Notices ONR-IN-17-003 and ONR-IN-17-004 have been remedied in line with the respective schedules.

Interventions Carried Out by ONR

The intervention consisted of an inspection of DRDL's arrangements for control of lifting operations on 9 Dock and for control of Examination, Inspection, Maintenance and Testing of the associated cranes with a specific focus on confirming the robustness of the implementation of these arrangements. The scope of inspection was limited to the 9 Dock RAH crane and 9 Dock Dockside cranes.

The Improvement Notice closure inspection was undertaken by three ONR Principal Site Inspectors and involved examination of relevant licensee documentation, targeted discussions with relevant members of the licensee's staff and an inspection of lifting operations and crane maintenance activities on the 9 Dock facility. 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). In reaching judgement on the adequacy of the improved arrangements, additional confidence was provided from the findings of previous interim readiness inspections undertaken by ONR.

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 extensive sampling into the amended arrangements and improvements that have been made by DRDL in relation to the planning, organisation, control and supervision of crane activities within 9 Dock.

The amended arrangements were reviewed and tested against the detailed schedules identified in the Improvement Notices and we confirmed that the requisite improvements had been implemented. This conclusion was supported by the findings from independent reviews undertaken by the internal regulation function of the licensee. Inspection and observation of lifting operations and crane maintenance activities on 9 Dock provided confirmation that as well as improving the arrangements, these had been adequately implemented. In reaching our conclusion that the contraventions identified in the notices had been remedied, the ONR inspection team noted that whilst DRDL are now judged to be legally compliant, enhanced arrangements are still required in a small number of operational areas with a Forward Action Plan in place to roll out improvements across the wider DRDL site. We reviewed the governance arrangements that are in place for management of this Forward Action Plan, confirming their adequacy and will monitor the delivery of the required improvements.

Conclusion of Intervention

On the basis of evidence obtained through inspection of the arrangements, detailed questioning of a wide range of DRDL staff and observation of lifting operations and maintenance activities, the we concluded that the licensee has made the necessary improvements to demonstrate that adequate arrangements are in place, and have been implemented, for the safe control of dockside lifting operations and crane maintenance activities on 9 Dock.

A letter will be sent to DRDL confirming that on the basis of the information provided and evidence obtained during this intervention the contraventions identified in Improvement Notices ONR-IN-17-003 and ONR-IN-17-004 have been remedied in line with the respective schedules.
