10% capacity increase through a Performance Agreement at Fibre-Excellence
Aug 19, 2015
Sappi’s Kirkniemi mill extended its cooperation with Valmet to a service agreement covering various services and spare parts for all of their three papermaking lines. Especially the tail threading equipment maintenance needed the expertise skills that were not sufficiently available in-house.
Valmet’s Sappi Kirkniemi frame agreement covers the following:
- Valmet Seal Strip Flex* suction roll seals
- Tail threading
- Refiners & deflakers (exchange units and spare parts)
- Valmet Winder Belts**
- Air systems for PM3
- Slitter management
- Grinder segments
- Doctor blades
- Fabrics
The agreement also covers refiner and deflaker shaft units and loading devices. Previously-stocked units are used as needed with Valmet purchasing exchanged units for later use. Valmet’s task is to keep the required number of parts in stock at all times. With 19 refiners and 5 deflakers to look after, mill inventory costs will be drastically reduced and the condition of replacement shaft units and loading devices is assured.

Summary
| Location | Kirkniemi, Finland |
| Customer target | The primary goal of the project was to improve the operational reliability and safety of the tail threading process. Also opportunities for wear part inventory savings needed to be recognized. |
| Solution | A service agreement covering audit and maintenance plan on all three machines, emergency service with short response times and availability of spare parts. Also the availability of the automated tail threading equipment was guaranteed. |
| Results | The agreement allowed the mill to plan better and reduced maintenance shutdown surprises. Considerable inventory savings were gained as the mill-owned stock of spare and replacements parts was reduced and provided from Valmet’s nearby warehouse. |
