Taking care of critical assets with Mainsaver CMMS

Harvest Energy’s biodiesel production plant on Teesside has an output of capacity of 250,000 metric tonnes per annum, making it the largest such plant in the UK and one of the largest in Europe.

Procurement of a software solution to make the process of scheduling preventative maintenance jobs on critical assets quicker and more efficient.


At the initial meetings to plan the assessment process for competing CMMS solutions, it emerged that a number of the plant’s engineers had already worked with Mainsaver CMMS in previous jobs at other industrial sites. This proved a significant factor in its eventual selection.

The first stage of the implementation was to install the three core Mainsaver modules, Maintenance, Materials and Purchasing. This was followed by collection, formatting and upload of plant and asset data into the CMMS. A criticality score was then assigned to each piece of equipment and a brand new preventative maintenance schedule was created based upon those factors.

The final stage was a comprehensive onsite system training programme for the engineering team on each of the new modules. This early user engagement, combined with Mainsaver’s renowned ease-of-use, meant that the project was able to hit the ground running.


An immediate, measurable reduction in instances of machinery breakdown entirely attributable to the implementation of the new ‘critical asset’ PM regime supported by Mainsaver CMMS.

“Mainsaver is a fantastic system, with which we have been able to plan and prioritise our plant maintenance activities to great effect.”

The Teesside manufacturing plant was recently acquired by Greenergy Biofuels, which, despite other options being available, opted to retain the best-practice PM regime managed in Mainsaver.
