One of the world’s largest forest companies, Chilean Arauco, began its largest investment project in its history in 2018, when a new white liquor plant was planned in central Chile. Pinja got involved in the plant’s design project together with the technology company ANDRITZ. Usually a straightforward factory design project received additional spice from demanding seismic calculations.

Challenge

Technology company ANDRITZ was one of the main suppliers in the design project of a new white liquor plant that would be built next to Arauco’s old factory. ANDRITZ was looking for a partner for this challenging project. The partner was sought through a traditional competitive tendering, and Pinja was eventually selected as a partner, especially because of Pinja’s experience.

Ensuring the safety and durability of the new plant was of crucial importance, which meant that there was no room for error in the project calculations. 

– Pinja possesses the kind of computational skills that were definitely an advantage in this project. They also had experience in designing similar plants, says Timo Falck, Project Engineering Manager for the white liquor plant product group at ANDRITZ.

What made this specific project especially interesting was the site location in Chile, where the collisions of tectonic plates cause earthquakes, adding more challenges to the design work in the form of numerous necessary calculations. The area in question is particularly prone to earthquakes, which is why the new plant was required to endure earthquakes of magnitude 10.

Project in brief

Solution

The production facility planning process for the white liquor plant included the designing of pipelines, steel structures and construction assignments, all areas in which the Pinja employees have extensive experience. The challenge was embraced boldly, and the project was kicked off smoothly.

A straightforward production facility planning project was spiced up by the calculations related to seismic movements and earthquake waves. The computational requirements had become increasingly strict in Chile in the past few years, and the completed calculations had to be approved by three parties before they could be taken forward. However, the project proceeded smoothly, as Pinja had competence and experience in the specific field of physics and had completed projects for similar conditions before. In the process of ensuring the durability and safety of the plant, Pinja collaborated closely with the local consultants.

Furthermore, Pinja sent the company’s own employees to the site to ensure that all the project stages proceeded smoothly, and to improve the overall flexibility of the project. With a project manager on site, Pinja has been able to make quick decisions more nimbly and monitor the progress.

– At first, there were quite a few unresolved issues, as this was an extremely challenging project. Due to the plant’s location, the seismic requirements for the plant are the strictest in the world, which initially caused some resource shortages due to the additional work. In the end, however, everything went well, and we were able to find solutions to the challenges, Falck describes the process.

End result

The plant in question consists of multiple parts, and seamless collaboration with the suppliers and subcontractors has been an essential part of this project. Despite the many moving parts, the project has progressed smoothly. 

– Pinja’s key strength is flexibility. In our collaboration, the key elements have been understanding our needs and knowing the overall process. Pinja understands their customers and can find solutions even in unclear situations, says Falck.

– In terms of challenges, this project has been one of a kind. However, it all worked out well after the initial complications. We are satisfied with the cooperation and communication with Pinja, and we will be happy to work with them again in the future. Our main impression is that if Pinja can handle a project like this, we do not have to question their expertise and we can trust them also with our upcoming projects, summarises Falck.

”One of the most significant recent projects with Pinja was the total upgrade of the trial test process and loading automation at Wärtsilä Vaasa, also including bus protocol modifications. A challenging aspect in this project was that the entire modification was completed without any major production breaks.”
