Long Term Periodic Review

Our client was required, as part of the Long Term Periodic Review (LTPR) task, to undertake assessments of the current safety requirements of the plant in order to substantiate that the Safety Systems & Components (SSC) will deliver their required Safety Functions. Tenet was contracted to produce an initial phase assessment of the SSCs against the Periodic Safety Review (PSR) Engineering Schedule and to produce a report outlining all the shortfalls including a review of the existing Design Justification Reports (DJR).


We were then contracted under a separate framework agreement to review the current SSC assessments in the Control, Electrical & Instrumentation (CE&I) Design Assessment Report (DAR) in line with the Engineering Schedule in use at the time. The SSCs were grouped under topic areas which corresponded to operational functions of the plant.


Effective collaboration was essential between all parties involved to ensure a consistent quality of output for the DARs. Key Tenet personnel with security clearance were given the necessary training to become monitored workers to enable access to the building to allow them to perform plant walk-downs to assess the current condition of the equipment. Any outstanding information was obtained through liaison with site based System Engineers.


The collaborative and open approach enabled Tenet to deliver a high quality suite of drawings and documents and costs were controlled by the ability to utilise the most appropriate resources available in the design office. The project was delivered quickly and to a high standard, with Tenet gaining many plaudits both informally and through our customer feedback process.
