VALMET AB, SCA ÖSTRAND EVAP

SCA Östrand, Evaporator plant installation

Nordic Power Service Oy delivered under contract with Valmet AB, SCA Östrand Mill Evaporation plant main and auxiliary equipment, and piping installations among the overall mill expansion project. Delivery included also full supply and management of piping prefabrication including materials, as well as NDT inspections and tower cranes for lifting. Project became the biggest delivery in NPS history.

Project preparations and prefabrication was started end of 2016, and site works in March 2017. Mechanical Completion was achieved in October 2017. At the mill shut down peak installation NPS overall site allocation was nearby 200 persons. Total piping length reached over 13 km, total weight of installed equipment over 2250 tons, biggest individual equipment lifted being 230 tons with height over 23 m. Project was challenging due to extremely short overall installation schedule. Evaporation plant full operation in commercial use took place soon after commissioning period in the beginning of 2018, and the plant is functioning well.

VALMET AB, SÖDRA CELL VÄRÖ MILL EXPANSION
Fiberline piping installation

Being the biggest project in the company’s history, Nordic Power Service delivered Fiberline Piping Installation to Södra Cell Värö Mill in Sweden, as main contractor to Valmet Ab. Project was started with workshop prefabrication and site preparations at second half of 2015. Site installations were started half a year before the main mill shut down in May-June, and project was completed in August 2016. Installations included in addition to the main portion of stainless steel piping certain special materials as titanium, and also large scope of FRP (Fiberglass Reinforced Polymer) piping. Delivery scope covered also scaffolding works and NDT inspections by the respective subcontractors. Project’s main challenge was tight shut down period schedule. During the mill shut down peak installation NPS overall site allocation was over 200 persons. Project execution was successful, evidencing NPS capability to run large and demanding project deliveries.

VALMET, MONDI DYNÄS AB
Modernization project

This highly demanding modernization project was carried out together with Valmet and Mondi Dynäs in spring 2015. Project included installation of new super-heater 3 and roof tubes, modification of super-heater connecting pipes and re-location of upper part soot-blowers and new wall panels, as well as installing a new lower rear wall of the furnace. Replacement of all air openings with window welds added extra challenge to the project. In addition, air distribution system on lower part of the furnace was modified and new boiler bank ash hopper and conveyor, and smelt spout cleaning robot were installed. Successful completion of this very complex modification project reflects the highly skilled workers and top of the market know-who of the NPS team.

We participated in the modernization from the planning stage until the NDT inspections and the whole project was executed in a close cooperation with the customer. The project is our company’s largest single delivery so far.

ANDRITZ, KOTKA MILLS OY
The bottom exchange of a recovery boiler

We implemented an extremely demanding project for Andritz and Kotka Mills Oy. In the project, we changed the bottom of a recovery boiler. The project included several challenging elements and its successful outcome reflects our company’s core know-how and the expertise of our team.

In addition to the tight schedule, the tangent pipe wall solution of the boiler together with the Sanicro38 material brought their own special challenges to the project. In spite of this, we managed to perform the work in the world record speed, only in 6.5 days.
