Mobile work supervision utilised during UPM Kymi’s maintenance shutdown
Empower was the main contractor for UPM Kymi’s annual maintenance in autumn 2017. Mobile work supervision was utilised in monitoring the service maintenance and alteration tasks carried out during the shutdown. It provided UPM with nearly realtime information about the progress of different subprojects and phases during the most extensive shutdown the pulp mill has ever undertaken.
The annual maintenance at UPM Kuusanniemi’s pulp recovery unit was carried out in October 2017. Empower was responsible for the annual maintenance of the recovery boiler, the evaporation plant, the causticising plant, the lime sludge reburning kiln and auxiliary equipment. It took two days to shut down the pulp mill and the maintenance shutdown started in mid-October. After the mill was shut down, there was slightly over a week of hectic work around the clock so that the mill could be restarted according to the planned schedule. During the production shutdown, Empower piloted mobile work supervision, the aim of which is to bring more transparency to the project and provide detailed information on the project’s progress.
– There were roughly 80 Empower employees on the worksite. Forepersons were provided with tablets for receiving assignments and marking them as completed. The daily entries enabled us to monitor how much time each task was taking and what their percentage of completion was, to react quickly to deviations and to ensure that we had the right professionals in the right place at the right time, says Mika Ruutiainen, who has been responsible for developing mobile work supervision at Empower.
The annual maintenance of a pulp mill involves numerous phases and interconnected tasks, so one of the key success factors is thorough advance planning of the project, the division of the project’s tasks and the careful planning of subproject interfaces.
– With the customer dashboard, we provided UPM with information about the progress of the assignments that we were responsible for, always for each morning meeting, so that they could get an overview of the status of individual tasks and the entire project’s percentage of completion. As a result, UPM’s control room was well equipped for directing the entire project and ensuring that the shutdown was completed on schedule. The information collected will also help them in the planning of future shutdowns, Ruutiainen goes on to say.
Kymi’s maintenance shutdown was a pilot project for Empower’s Smart Industry business’ mobile work supervision, which provided a lot of valuable information for developing the functions and specified in more detail what is sought with the future tool.
– Our goal is that, in future, mobile work supervision will be used in all Empower projects and that we digitalise our own production from the project launch all the way to customer invoicing, says Empower's CBDO Eero Paunonen. At the same time, we also conduct mobile risk assessment in order to review the existing working environment appropriately and to identify and assess all potential risks before work starts. The customer dashboard gives all parties immediate insight into the progress of work and the percentage of completion.
