Barrow – LC19 and LC22 inspection

Executive summary

Purpose of Intervention

This intervention, conducted at the BAE Systems Marine Limited (BAESML's) licensed site was undertaken as part of the 2017/18 intervention plan and propulsion sub-division strategy.

Interventions Carried Out by ONR

I conducted a themed compliance inspection (“plant design & status”) comprising licence condition(s) (LC) 19 ("construction or installation of new plant"), 20 ("modification to design of plant under construction"), 21 ("commissioning") and 22 ("modification or experiment on existing plant").  The focus of this inspection was to ensure that the Licensee’s arrangements are adequate and have been appropriately implemented and applied to construction, modification and commissioning activities, both completed and in-progress (including the site redevelopment programme, referred to as SRP). 

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

No matters were identified as requiring immediate regulatory attention during the conduct of the compliance inspection.

It is my opinion that the arrangements for licence condition 19, 20 and 21 are adequate, based on the aspects sampled for this themed intervention. 

It is my opinion that there are areas for improvement relating to the licence condition 22 arrangements with respect to the classification of modifications and the management and tracking of modifications.  In addition there is an opportunity to include learning from experience generated from the site redevelopment programme in the arrangements for hold point control.

Conclusion of Intervention

Overall I judged that the implementation of the site’s arrangements with respect to “plant design and status” was adequate. 

I have raised a regulatory issue to monitor the required improvements to the LC22 arrangements.
