Asset Optimisation

Interfleet's multi-disciplined team has a wide range of experience in all aspects of Asset Optimisation, including Data Management, Maintenance & Overhaul Cost-Reduction, Reliability & Availability Improvement and Risk Assessment. Interfleet has a proven track-record in cost reduction, extension of overhaul periodicities, strategic reviews of maintenance regimes, benchmarking of maintenance practises, maintenance risk assessment and risk reduction. Working across all facets of the rail system, Interfleet can examine whole-life maintenance and overhaul cost optimisation.

Interfleet's suite of Asset Optimisation consultancy tools include:
  • Reliability Centred Maintenance (RCM)
  • to maximise maintenance activities for improved reliability, through analysis of the modes and effects of component or system failure. Interfleet has carried out sharply-focused RCM studies for clients, realising significant benefits in terms of improved reliability, reduced maintenance downtimes, extensions to maintenance periodicities and increased effectiveness of maintenance activity for both day-to-day maintenance and major overhauls. Interfleet has also provided RCM training packages for maintenance staff.

  • Maintenance Regime Analysis (MRA)
  • , a holistic approach to maintenance policy, devised by Interfleet. The aim is to consider maintenance and overhaul regimes in a wider perspective and determine if any activities can be combined or streamlined. For some rail systems, the analysis may reveal that the current maintenance regime includes many time consuming and detailed checks and tests which are performed to determine when the component is about to fail. These can be replaced by condition based monitoring (such as oil sampling or vibration monitoring) where they are more cost effective.

  • Overhaul Extension Projects
  • to optimise the periodicity at which vehicle or component overhauls should take place. Often these projects are carried forward using MRA techniques, but Interfleet can also carry out life-cycle costing calculations and by benchmarking against current best practice, we can establish the optimum periodicity to carry out overhauls. Any potential problems are identified and targeted early on in this type of project, and by calling on the expertise of Interfleet's Mechanical and Electrical engineers, we are able to categorise all systems/components according to their suitability, thereby focusing resources on the areas likely to bring the greatest benefit. Further investigative work is also usually carried out, often including technical analysis at overhaul, condition assessment, trials, destructive and non-destructive testing, and monitoring of critical equipment.

  • Failure Impact Reduction (FIR)
  • is a technique pioneered by Interfleet, to ensure that the most appropriate responses to system breakdowns are implemented. The techniques include scenario modelling and engineering and operational decision trees, resulting in user-friendly handbooks and an efficient systematic approach to failure reporting.
