Asset Management

SCL provides training and consultancy in Reliability-centred Maintenance (RCM). RCM is a process for determining what must be done to ensure that any physical asset continues to do whatever its users want it to do. The process encompasses 'maintenance' activity, design and logistic support. Our experience to date with RCM has delivered reductions in maintenance resource requirements of between 30% and 70%, invariably with improvements in operational availability. The RCM methodology is no less than a formalised approach to applying risk management principles to functions which are usually associated with physical assets - but the process is equally applicable to business procedures, processes and institutions.

Although we have applied RCM to a number of mechanical and electrical systems, we particularly specialise in RCM within electronics and recent RCM studies for the Royal Navy have included command and control systems, weapons, communications, SCADA systems, nuclear reactor protection and control systems. We have recently completed reviews of the Rapier FSC missile system and High Velocity Missile system for the British Army in which substantial reductions in maintenance effort and improvements in operational availability have been identified; we reviewed the maintenance for the Scout helicopter of the Historic Air Flight and are currently conducting RCM reviews on the CVR(T) fleet of armoured fighting vehicles, including structural integrity issues. These studies into structural integrity are now being carried forward into the Warrior fleet of fighting vehicles.

We have successfully established the optimal range and scale of spares necessary to support RCM-derived maintenance strategies in some of our RCM studies, based on Reliability-centred Stockholding (RCS) but using a genetic algorithm approach to the spares optimisation problem, together with a realistic assessment of the risk inherent within the traditional sparing assumptions.

We provided support to the Royal Navy and Royal Fleet Auxiliary in coordinating the on-board maintenance management of two new-to-service ship classes, to ensure that RCM studies are kept 'live' and to undertake supporting database management activities.

We formulated the business processes for rolling out RCM within the Royal Navy and ensuring that its supporting management systems are implemented expeditiously. To this end, we have developed a Visual Basic tool for the derivation of the optimal upkeep cycle for a number of platforms, to identify the periodicities and duration of support periods alongside and in dock.

We have worked with the Royal Navy to produce a Naval Engineering Standard - NES45 - 'Requirements for the application of RCM to HM ships, submarines, Royal Fleet Auxiliaries and other naval auxiliary vessels'. This naval standard is now Def Stan 02-45 and we were part of the peer group for the tri-service version based on this standard, Def Stan 00-45.
