Condition Monitoring

This Prior Information Notice (PIN), without call for competition, is to alert the market and all interested Suppliers to a Contract Opportunity which will be conducted through the Sellafield Ltd Dynamic Purchasing System (DPS). Sellafield Ltd is intending to procure the Service of Condition Monitoring through the Engineering and Technology Solutions Marketplace Dynamic Purchasing System (DPS) (C12362) (Engineering Services Category, Testing and Substantiation Sub Category).

Further details in relation to DPS and how to register have been provided in section 11.2.4.1 Description of the Procurement. Condition Monitoring (CM) is carried out to prevent unexpected equipment failures, avoid costly downtime, and extend asset life by using sensors and other monitoring hardware to detect early signs of problems (for example vibration or temperature changes) in machinery.

Enabling proactive & planned maintenance instead of reactive repairs, CM improves safety, optimises spare parts, increases uptime, and makes maintenance more efficient and cost-effective. As the CM equipment continues to collate data, the engineering and maintenance department can make key Condition Based Maintenance (CBM) decisions on maintenance schedule periodicities and plan and procure spares ‘Just In Time’ (JIT) in lieu of having multi-million pounds worth of assets / spares being sat in the stores in case of failure.

Digital Transformation is now aligned to the Sellafield Limited (SL) strategic objectives, regulatory expectations and efficiency savings agreed with the Nuclear Decommissioning Authority (NDA) and SL have been mandated to digitally transform Asset Management activities across the full asset lifecycle. The Digital Asset Management (DAM) team are integrated within the Engineering Centre of Excellence (ECoE) and CM teams and working closely together to fully understand the asset lifecycle and confidently predict potential failure and to understand when a timely intervention is required.

Suppliers must meet or be working towards ISO 9001, 14001, and 45001 standards and ensure the personnel can obtain SC clearance and Sellafield P4 access if required. They must provide clear project planning, robust quality assurance, and deliver safe, compliant, and reliable CM/CBM services across the estate.
