Avoiding costs in replacement of mass flows by increasing the longevity of existing mass flows with an upgrade to a tablet interface. If the company decided to replace the existing units they would look to replace 20% of the units per year and if these were upgraded instead of replaced this could save around £390,000 annum. These numbers are based on an engineering estimate of £15,000 per new unit as appose to £2,000 for an upgrade and a total fleet of 150 units.
As part of National Grid longer term plan to replace OITH devices on site, this project could help influence what device is chosen. This could then help to reduce cost as one device could then be used for multiple tasks, and the condition monitoring devices could be less complex as the interface is already onsite.
The project benefits above are based on replacement of the existing 150 units on the system, if the company upgraded the units instead of replaced them, we could save £390k p/a
