In 2000-2002, UPM-Kymmene had a new, modern power plant built at the Jämsänkoski Mill. The new plant was designed to be built in the middle of the operational, built-up mill area, and the space available for high-temperature and high-pressure pipes, cables and equipment was limited by the existing constructions.
In these circumstances, the Cadmatic 3D software revealed its true power. The designers at Jaakko Pöyry used both the Cadmatic software and its 3D and database capabilities in engineering the turbine hall.
The power plant was designed by the engineering company Electrowatt Ekono using the Cadmatic 3D and its 3D capabilities in engineering the turbine hall. The Cadmatic 3D model and the data entered into the database during the planning stage was then a base for future plant maintenance. However, since the boiler unit supplied by Foster Wheeler to Jämsänkoski was designed by the manufacturer by using another system and format, there was no ready-to-use data structure available for maintenance purposes.
To obtain a single uniform model and database for plant maintenance, the boiler unit data were transferred into the Cadmatic system and re-modelled. The re-modelling was performed by Elomatic. According to Project Manager Hannu Lamberg, the work advanced smoothly; some parts of the model could be directly converted and some were re-modelled
A tool for maintenance
Martti Heinänen, Project Manager responsible for the Jämsänkoski and Kaipola Mills at UPM-Kymmene, says that the Cadmatic model was selected for a number of reasons. One advantage of the model is eBrowser, which is an easy-to-use and inexpensive solution for data retrieval, virtual viewing, and document printing.
"We wanted to integrate all the data needed for the future maintenance of the power plant into the same model. This process took some time, because the boiler unit's database could not be directly utilised, but instead, we had to go through all the details piece by piece. Now, the work is more or less completed, and in the future, we will continue to update and maintain the Cadmatic model. It is important for us to learn how to use it in the most appropriate and efficient way. We have just come to the end of the training period, so we do not have many practical experiences yet. My own experience is that the software is functional and user-friendly", says Martti Heinänen
Heinänen adds that another factor speaking for the selection of Cadmatic was the feasibility of the model in overall plant and equipment engineering. This will definitely be a synergetic asset in the future, whenever any investment needs arise at the paper mill itself.
Full benefit through training
The modelling was completed by early 2003, and a licence contract for Cadmatic Software was signed. Both eBrowser and Plant-Browser allow the user to virtually move around in the three-dimensional model, to retrieve data embedded in the model, and to print out hardcopies of the model. User training started in February, with Support Engineer Pekka Puranen from Cadmatic as the instructor.
"Production and maintenance managers, as well as engineering staff responsible for documentation participated in the training. They were particularly pleased with the fast, web-based eBrowser and its capabilities. Being extremely easy to use, eBrowser allows for efficient data retrieval. After the course, the participants seemed to be satisfied: they had received the information they had expected from the training", states Puranen.
Cadmatic Oy has vast experience in utilising 3D design data in plant maintenance, as well as producing data structures appropriate to maintenance and customising integrated solutions for operation. Consulting and training services are offered to customers in various industries. For the pulp and paper industry, experience has accumulated from projects for UPM-Kymmene, M-real, Stora Enso, Metsä-Botnia and SCA mill investments, for example
