Restoring Availability and Affordability Across Legacy Naval Platforms
The Contractor held a long-term contract to provide maintenance and logistics support for a class of navy ships at an agreed level of operational availability. But the platform was not meeting the contracted readiness target, creating sustained operational pressure and commercial risk.
The challenge was not simply to do more maintenance. The Contractor needed to determine which maintenance actions were delivering value, which systems were underperforming, and how maintenance approach and periodicity could be changed to improve availability in the context of real mission profiles and operating environments.
Just as importantly, the Contractor needed a defensible way to validate recommendations, quantify cost and readiness impacts, and communicate the analysis clearly to the customer. That required a model-based approach capable of linking operational usage, failure behaviour, maintenance strategy, and life cycle cost with confidence.
Model-Based Maintenance Optimisation and Validation Using MADE
The Contractor analysed maintenance records and used MADE to identify poor-performing components and systems that were failing more frequently than expected. This established where sustainment effort and availability loss were being driven across the fleet.
Using MADE, the Contractor identified potential changes to maintenance approach and periodicity for poor-performing components. This enabled alternative sustainment strategies to be assessed against real operational usage and operating environment assumptions.
Trade studies were performed to increase operational availability, model the impact of mission profile and operating environment on maintenance cost, and calculate the potential reduction in sustainment costs for the platform.
MADE was used to technically and economically validate design improvement recommendations, create a reusable knowledge base of failures and maintenance actions, and provide a clear means of communicating defensible analysis to the customer.
“MADE gave the Contractor a rigorous way to optimise sustainment strategy—linking maintenance decisions, mission profile, availability, and cost in one defensible model.”
Measurable Results. A Sustainment Strategy Built to Perform.
Improved Operational Availability
Alternative maintenance strategies were identified and assessed to increase platform readiness and close the gap to contracted availability targets.
Reduced Sustainment Cost Risk
Mission-aware cost modelling and maintenance optimisation identified how sustainment costs could be reduced without compromising operational outcomes.
Validated Sustainment Knowledge Base
Failures and maintenance actions were captured in a reusable knowledge base to support future decision-making across the life of the platform and contract.
