System Inspection of Assest Care of Civil Structures, DSLR

Executive summary

Purpose of intervention

I undertook inspection of PFR and DFR and other work in accordance with the inspection plan for 2014/5 with the intention of providing evidence that DSRL is controlling its hazards properly and is compliant with its statutory obligations.

Interventions Carried Out by ONR

I carried out interventions at PFR to establish compliance with the requirements of Licence Conditions 23 and 24 and completed follow-up work following an enforcement letter sent to the licensee, associated with the control of work following a recent event at PFR.

I carried out a systems inspection accompanied by a specialist inspector and the nominated site inspector regarding the licensee management of asset care relating to civil structures as part of an ongoing intervention plan. In addition, I met with DSRL senior managers to progress recent safety case and management of change submissions.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

The detailed findings associated with the asset care systems inspection are reported separately. Overall ONR concluded that the DSRL arrangements in this area were deemed to be adequate, and were being complied with, although there was evidence of poor practice in some areas and a number of actions were placed on the licensee in response to this.

My inspection at PFR provided me with assurance that significant and systematic improvements have been made to the arrangements, and that implementation is satisfactory. I am of the opinion that PFR had achieved a good standard of compliance against the requirements of Licence Conditions 23 and 24. I also judged that PFR was compliant to an adequate standard with the requirements of Licence Conditions 27 and 28.

I reviewed learning on the site following the caustic event at PFR and judge that the site has taken adequate action to prevent a reoccurrence.

Conclusion of Intervention

PFR is now complaint to at least and adequate standard against the requirements of Licence Conditions 23, 24, 27 and 28.

The licensee has generally adequate arrangements for the delivery asset care of its civil structures although a number of actions were raised against the areas where poor practice was noted during the inspection. ONR intends to follow up these improvements and any further asset care interventions as part of normal inspection against the requirements of Licence Condition 28.
