Our approach to developing effective maintenance solutions has significantly advanced over the last three years. Our methodology for creating maintenance regimes based on the assets actual operating context remains core; however we have developed numerous tools and techniques, detailed within our proposal, to underpin this process and add significant value to our customers, whilst also reducing risks.
Our multi-stage approach to understanding an assets actual operating context provides the asset stakeholders with a unique level of visibility regarding the assets criticality attributes - such as capacity, size, condition, system redundancy and risks of failure. Combined with our detailed mitigation plans, incorporating the latest condition monitoring technology and detailed maintenance plans, we use Failure Modes effect analysis to derive at the appropriate regimes for the asset, rather than ‘out of the box’ SFG20 tasks, that have not been based on the individual assets operating context or condition.
Furthermore, we have now evolved our maintenance regimes to include environmental aspects which cover system downstream, building envelope and external impacts. Our regimes, as a result of these additional dimensions, now include pollution control and technical cleaning as part of our mitigation plans. This has recently been deployed on all of The Talk Talk Group’s critical datacenters to ensure that asset life is preserved by preventing oxidization and improving energy efficiency, through electro lubes to reduce arcing and the removing of harmful dust which is increasing mechanical and electrical resistance.
The output of our engineering consultancy work, systemization and mitigation plans will all be visible in our engineering management system, along with real-time alerts for condition alarms, distribution bay capacity alerts and engineering performance deviations. This valuable data will enable us to further tune our maintenance regimes based on asset performance and usage.
Once we have undertaken the detailed engineering consultancy works and derived the risk based maintenance regimes, our methodology for delivery is also designed to reduce waste and increase schedule adherence. Our planning team and consultants will create a program based on splitting the activities using Single Minute Exchange of Dies (SMED) where tasks will be grouped on-line and offline, to enable planned engineering downtime with your users and understand those tasks that will not affect business continuity. Furthermore we would also schedule the regimes in to maintenance trains this will allow our teams to plan maintenance visits, system by system throughout the cooling train, power train and protection trains to give a full system service across all the systems assets in the shortest period of time. This has the added benefit of reducing the frequency of down time required to undertake the off line activities.
