Reducing costs and operational risk, while improving asset reliability and safety, through a robust approach asset maintenance

Our overall philosophy towards maintenance focuses on lowering costs, reducing operational risk and improving asset reliability and safety. We apply a five-step process to achieve an optimal maintenance program:

  1. Set targets – Develop performance targets, health indicators and bespoke reporting suites that meet specific requirements, such as the Naval Technical Regulatory Framework, and consider both short and whole-of-life perspectives.
  2. Develop worklist, schedule and cost – Define the work scope, including all planned and corrective maintenance and engineering change activity, together with scheduling and costing to inform any trade-offs required between cost and scope.
  3. Understand the Class requirement – Consider the aggregate work scope and identify any class risks and opportunities.
  4. Resourcing – Conduct resource planning to identify any resource conflicts particularly for specialist resources.
  5. Trade off option consideration – Review work scope to ensure it will meet the required performance outcomes and consider trade-off options when these are compromised.

We accurately determine and plan maintenance requirements over the short, medium and long-term, providing customers with clarity of future expenditure profiles. This is coupled with a risk-based analysis that provides options to optimise asset availability and capability, within any given budget constraints. The development of tailored, standardised work instructions are another tool we use to reduce the cost of maintenance and improve data integrity.

Anzac Class Frigate Maintenance

In 2012, NSM won the Group Maintenance Contract for the repair and maintenance of the Anzac Class Frigates delivering directly to the Anzac Systems Program Office (SPO). This contract quickly delivered significant program outcomes including:

  • 60% reduction in project management and other overheads
  • 20% cost savings compared to previous maintenance contracting arrangements
  • 135% increase in predictive maintenance tasks and corresponding decrease in corrective maintenance.

Building on this, in 2016 NSM was a key player in developing the Warship Asset Management Agreement (WAMA Alliance), for the continued sustainment of the Anzac Class Frigates through to the end of their life.
