Reliability & Maintainability Case: Queen Elizabeth Class (QEC)

BMT produced the QEC Reliability and Maintainability (R&M) Case Report, which provided assurance to the Ship Acquisition Project Team within MoD Defence Equipment & Support (DE&S) on the level of vessel availability as a snapshot during manufacture.

Summary:

BMT produced the QEC Reliability and Maintainability (R&M) Case Report, which provided assurance to the Ship Acquisition Project Team within MoD Defence Equipment & Support (DE&S) on the level of vessel availability as a snapshot during manufacture. The QEC R&M Case Report, is issued for in-service acceptance purposes, which equates to a ‘measure and declare’ event, supported by progressive assurance.

BMT held a number of stakeholder discussions with the Aircraft Carrier Alliance (ACA) members to capture evidence that provided assurance on the level of vessel availability and to identify risks that would result in the availability of the vessel in-service being less than predicted. 

Evidence included:

  • Predictive AR&M Modelling, using Systems Availability Model (SAM);
  • Initial Provisioning (IP) based on OPUS 10 spares modelling;
  • Failure Mode, Effects and Criticality Analysis (FMECA);
  • Reliability Centred Maintenance (RCM) studies;
  • Technical Analysis Reports;
  • Tender Assessment Documentation.

The QEC R&M Case Report presented a summary of the QEC R&M Case including:

  • The work undertaken against the R&M Plan and the overall process of progressive assurance;
  • The risks identified, the mitigating actions in place and any recommended future activities for the QEC programme.

Key Benefits:

  • Assurance of the predicted level of in-service ship availability.
  • Identification of activities that mitigate the in-service R&M risks

Key Features:

  • Presents the current position with regard to the Whole Ship AR&M characteristics based on the SAM modelling and available data.
  • Risk-driven approach in accordance with Defence Standard 00-42 Pt 3 and BS5760-18.
  • Proactive and flexible approach.
