Steel structures in the waterway
Hydropower is the backbone of electricity production in Norway. With 88% of the country’s power generation coming from water (SSB, 2026), we stand before an enormous field of opportunity. The Norwegian Water Resources and Energy Directorate (NVE) has estimated that upgrading and expanding existing hydropower facilities could unlock a techno‑economic potential of 6–8 TWh. At the same time, new power production will be necessary to meet increasing demand in the years to come. What does it take to complete these projects in a safe and sustainable way?
When new facilities are built, or existing production is elevated to a new level, high standards for planning and execution apply. In this context, steel in the waterway is not just a technical detail, it becomes a decisive part of the facility’s ability to withstand future loads.
Reliable choices
Well-executed projects begin long before the steel becomes part of the waterway. At Stryvo, we know that the decisions made early in a project form the foundation for successful execution. By involving us from the very beginning, the risk of errors and delays is significantly reduced.
Our engineers work closely with you as the customer, as well as with consultants, to ensure that all project solutions are tailored to both needs and requirements. Being closely linked to our own production and operators is a major advantage when decisions must be made at the drawing board. From the first sketch onward, we can provide optimal advice on material selection and dimensioning.
Tailored production
Once the plans are in place, the project moves into production. With three workshops across the country, we can bring together unique specialist expertise in our projects. For our customers, this means that we can deliver everything from small components to large, complex products.
For mechanical structures in the waterway, we can manufacture a wide range of products. We have extensive experience with various types of intake gates and dam gates, gate hoisting equipment, plate boxes, valves, trash racks, and minimum flow solutions. As part of waterway systems, we can also produce crossflow gates, pipe structures, and other pressure‑bearing components. In addition, we have developed our own trash rack cleaner called Wiper.
Stryvo has long experience producing complete steel buildings, as well as stairs and railings. As a full‑service supplier, you benefit from fewer points of contact and greater predictability throughout your project.
Optimized operations
Our experienced service team performs advanced mechanical services either from our workshops or directly at your facility. We carry out overhauls and repairs of bearings, motors, gearboxes, guide vanes, and turbine housings, and can also manufacture new components when needed. Metal stitching is a method we use when welding is not possible, and it has proven to be highly durable and cost‑effective. In the field, we can also offer all types of mobile machining, including planing, grinding, milling, and line boring.
By using our service solutions, you can extend the lifetime of existing installations, reduce downtime, and carry out upgrades in a controlled and safe manner.
Gain better control
Our understanding of the interaction between mechanical components in the waterway ensures stable control of hydraulic forces during operation. This applies whether your project aims to upgrade, expand, or build entirely new facilities. With a single supplier throughout the process, you gain better control, higher quality, and solutions that last for many, many years. By choosing Stryvo as your partner, you make a safe and reliable choice for your facility.
