Versowood selected Maintpartner to take responsibility over the maintenance of their Vierumäki, Finland plant

Versowood, a Finland-based sawn timber producer, has selected Maintpartner as its partner to be in charge of the maintenance of Vierumäki plant. The goal of shifting to the partnership model is to update the operating model and run systematic maintenance operations.

The contract enters into force and the 29-person maintenance staff at the mill will transfer to Maintpartner on 1 October.

Versowood is Finland's largest private forest industry group manufacturing a wide range of wood-based products. Vierumäki is their largest site, which includes two sawmill lines, glulam plant, pole division, pellet mill, as well as thermal energy and further processing plants. The 110-hectare production area has about three hundred workers. The Group has a turnover of approximately EUR 400 million and employs some 800 people in total.

“With this solution, we are seeking a new operating model for the entire unit. In today's world, it is important that production efficiency is constantly increasing. We have strong growth goals for the coming years, particularly at Vierumäki, and we believe that outsourcing is now the right solution for achieving the best and most cost-effective maintenance,” comments Ville Kopra, CEO of Versowood Group.

“We are very pleased with Versowood's trust and selection. Maintpartner has a solid track record of operating and maintaining various types of plants and projects, and has over a thousand industry professionals in Finland, so we are the right partner for Versowood to develop maintenance more efficient, systematic and proactive,” says Pasi Tolppanen, CEO of Maintpartner Group.

To develop its operations, Maintpartner places its own experienced professionals to Vierumäki: a maintenance manager and foreman, and, for the first year, a development engineer to support the development work.

The contract has a minimum duration of three years.

Maintpartner installed piping at Kiilto's new chemicals discharge point in Lempäälä, Finland


Maintpartner has installed all piping, pumps and valves for Kiilto Oy at their newest discharge point in the Lempäälä plant, where tank trucks discharge flammable chemicals into the plant's raw material tanks. The project improved the chemical safety of the plant by relocating the discharge point further away from the chemical tanks. In addition, an automatic foam extinguishing system was installed to the discharge site.

Maintpartner was in charge of the installation and welding of the new pipes. Qualified welders assembled the tank filling pipes according to the instructions of Maintpartner’s certified welding coordinator. Some of the steel structures over the tanks were prefabricated at Maintpartner's own workshop. The fitters installed the new pumps and valves to both the discharge point and between the tanks and the process. Finally, the tightness of the pipe joints was verified by a pressure test using nitrogen.

At most, a dozen professionals were involved from Maintpartner’s project, installation and engineering services, mainly from the Nokia office.

“During the construction, the plans still required refinements, which we managed in cooperation with the customer on-site,” says Esa Laine, work planner at Maintpartner.

“Maintpartner was chosen as a partner for the project because we had good experience from previous projects with them. The project included a lot of changes in an potentially explosive area, where safety and site management were the top priorities. The scheduling also played a big part because the warehouse had to serve the production throughout the project. The shortcomings of the plans were tackled in time by the contractor and quickly resolved. Maintpartner was able to respond well to changing needs in resources, and schedules were kept,” tells Vesa Juhannusvuori, Technical Manager at Kiilto Oy.

Kiilto is a hundred-year-old Finnish family-owned company that develops and manufactures chemical solutions in four different business areas: construction, industrial fastening and hygiene solutions, professional cleaning and hygiene, and consumer products. Kiilto continuously develops its sustainability: for example, the Lempäälä plant uses residual heat from glue production to heat the entire production plant and its hot water.

Maintpartner implements safety-enhancing improvements at UPM Energy's floodgates

In recent years, Maintpartner has renovated several of UPM Energy's hydropower floodgates at river Kymijoki, Finland. Maintpartner typically carries out the entire project including construction, engineering, dismantling, coating and installation works. The fourth renovation project will be completed this summer at Kaltimo hydropower plant in eastern Finland.

During the basic renovation, the motor drive, seals and other wear parts of the floodgate are renewed. The gate itself is sandblasted and re-coated. After the work is completed, the gate is as good as new - and operates better and safer with modern and environmentally-friendly technology.

The upgrade includes heating and venting systems in the gates to protect the gate surface structures from ice formation. New oil-free bearing solutions for raising and lowering side guides minimize the risk of environmental damage. Additional instrumentation accurately identifies the position of the gate and the need for adjustment that is controlled remotely.

The environment and safety are carefully taken into account in the renovation. The site is fully covered to prevent the blasting sand and paint waste ending up in the water. The gate is carefully supported in an upright position, and on the downstream side there are guardrails to prevent workers from falling into a steep rapid. Survival crafts and life buoys are always available at site.

“Continuous maintenance and upgrading of hydropower plants are important for maintaining plants so that they are efficient and environmentally safe. The amount of oil in the equipment has been significantly reduced, and the well-maintained plant works as planned also in exceptional situations – for example, during floods,” says Hydropower Manager Pekka Pollari from UPM Energy.

“We have personnel specialised in dam projects, and their expertise is crucial. Our project manager Pekka Nokelainen and our skilled technicians work in close cooperation with UPM Energy,” says Team Manager Teemu Torvikoski from Maintpartner’s Kouvola office.

The Voikkaa hydropower plant was originally completed in 1923 as the power plant of the paper mill of the then Kymmene Oy. Other tenants now occupy the former paper mill premises, and the electricity of the Voikkaa power plant is sold on the market. With a production capacity of 1,500 MW, UPM Energy is Finland's second largest producer of electricity who generates electricity in hydropower, nuclear power and CHP plants. The company's goal is to grow as a producer of CO2-free electricity and as an expert in industrial energy efficiency.

How the work progressed on the dam of the Voikkaa hydropower plant last summer:

First, the divers built a temporary wooden dam between the floodgate and the reservoir. The wood material was transported to the site on a ferry.

When the gate had been raised up and supported, the old seals were removed. The side guides were renewed, the rack rails repaired and the old motor drives removed. The new motor drives and their transmissions were installed on the newly-built foundations.

The floodgate technology was renewed including the heating and venting systems. The gate was sandblasted, the damaged parts repaired, spackled and painted.
Finally, the leak tightness was secured by adjusting the new seals, and the renewed gate was put into service.

Energy audits - an inspiration to people, good for the environment

Maintpartner regularly conducts energy audits of its operations. In 2018–2019, the audits were carried out entirely under the guidance of our own experts - the latest in Sweden, where energy use and its potential for savings in Karlskoga and Degerfors sites were examined. They employ the majority of Maintpartner employees in Sweden, some 170 people from over 250. In addition, Maintpartner has eight other smaller offices in Sweden.

In general, energy audits generate many ideas for improving energy efficiency in an industrial environment. Maintpartner's customers can also benefit from this experience, as it is available for them as a service.

“People are often somewhat astonished at how simple methods can make a big impact. When this is noticed, they become keen on taking on more actions. The most important thing, however, is that there is a named person responsible for energy efficiency in the company – someone to ensure continuous development,” says Matti Yliknuussi, Maintpartner's energy and environmental expert.

Most of the challenges are related to being located in industrial facilities, which may have been designed and built decades ago with the primary purpose of providing protection to production machinery. At the time of construction, no attention was necessarily paid to environmental and energy issues. Furthermore, understanding the impact of conditions on both production and the life cycle of equipment as well as on human well-being and occupational safety was not at the current level.

What can be done? Often, the first measures concern the management and tendering of electricity contracts and the selection of renewable electricity. Exterior doors and hatches of old premises can be easily sealed, and window glazing increased.

“The old infrastructure brings its own challenges, and it has to be recognized that not all measures are realistic - especially if you are operating in leased premises,” says Matti Yliknuussi from Maintpartner.

Clear choices include the purchase of heat pumps, the replacement of old radiator thermostats, ventilation machines and lighting, and the addition of controls. At Maintpartner, the teams had already independently made environmentally friendly upgrades on e.g. lighting and windows.

“An energy audit is a great opportunity to truly develop the environmental responsibility of operations. There are always opportunities for development. At Maintpartner, we even went further and chose a broader scope for the audit than required by the European Energy Directive, so that we can certainly make the most of our potential and will be able to develop our operations in a more systematic way in the future,” concludes Yliknuussi.
