Devonport Royal Dockyard Ltd, Plymouth LC11 Compliance Inspection

Executive summary

Purpose of Intervention

This report covers attendance at the Devonport site for routine engagement and inspection activity. The inspection was undertaken as part of a series of planned interventions supporting ONR’s DRDL Intervention strategy.

Interventions Carried Out by ONR

ONR carried out a planned LC11 (Emergency Arrangements) compliance inspection on site.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

ONR and DNSR had previously judged that overall the Joint DRDL / HMNB (D) Level 2 Emergency Exercise Short Sermon 16 (SS16) carried out in September 2016 had been an adequate demonstration of the joint on-site plan and off-site emergency plan for the Devonport Site. However, although a formal re-demonstration was not required, ONR had requested that we observe a casualty rescue drill before the next joint Level 1 demonstration exercise scheduled for October 2017.

The relatively limited scope and extent of the exercise resulted in ‘live’ play being limited to the incident area and the SRC Forward Control Point (FCP). A team of ONR inspectors observed the emergency drill, in particular, casualty handing and rescue and team deployment and reception at the FCP.

ONR judged that there was an adequate performance of the FCP and the intervention teams and a significant improvement to casualty rescue and handover which addresses the issue raised during SS16. As is usual with emergency exercises / drills, some learning points were also observed which require consideration by DRDL.

Conclusion of Intervention

No additional regulatory concerns were identified as a result of this intervention and future engagement will continue as detailed in the DRDL Intervention Strategy.
