Metsä Fibre, part of Metsä Group, is building a new bioproduct mill in Kemi, Finland. The mill will be started-up as planned in the third quarter of 2023 and it is being built using the best available techniques (BAT). The technological level meets and even exceeds the EU BREF requirements. The project is implemented as buyer-driven subcontracting, which also allows for the participation of smaller companies. For local businesses, the mill investment createed demand directly related to the mill construction. Hilti Finland has been involved in the project in cooperation with TT-Teknologia and LVI-Pitkälä Lappi Oy as they have used the Hilti modular installation system Multi-duty channel system (MT) at the site.
- Hilti has supplied different support structures and brackets for the pipelines and ductwork, as well as the related documentation, the quality of which has been excellent. With the documentation, it has been easy to check and solve possible issues on the construction site and go through structural analysis and load capacities, says Jari Koskela, HVAC Manager of Metsä Fibre Kemi bioproduct mill project.
According to Koskela, when someone proposes bearing load structures for a project, there must be plans so that the structure can withstand the load. - In this case, the quality of the documents was so clear that there was no need to make any changes or to go over them with a Structural Engineer. Based on the documentation, the installation work could be started immediately on the construction site. It has made the progress and operation of the project easier on an everyday level, he says.
The installation environment has been done at a height and this has created issues to be considered to ensure safe working. The MT installation system has proven to be a functional in many ways. - When I have visited the site and seen the installations on the wall, the impression has been neat and the hangability good. The best thing is that it has not been necessary to do any welding on site. Similar work could be done with steel, which must be welded and painted. Now those work phases have been completely omitted.
According to Koskela, all the requests from Metsä Fibre to Hilti have been channeled through TT-Teknologia and LVI-Pitkälä Lappi Oy. - In my opinion, this three-way co-operation with our partners has worked out well.
