Hydropower Safety

Our Aqua-Guardian product range provides visual and physical safety barriers for lakes, reservoirs, dams, waterfalls and rivers. 

A wide range of standard products help prevent people and floating objects from entering dangerous areas – reducing downtime for hydro-electric plants, and keeping people safe.

In cooperation with our partners at Vassfall, we produce and install equipment tough enough for the extreme and challenging climate in Northern Europe. Our products resist the rough conditions and remain in position during periods with extreme weather, flooding, waves, ice, changes in water levels, strong currents and wind.

Our expertise


Our expertise is your safety

We understand that minimising risk requires more than just high-quality products. Expertise in product usage, mounting, and inspection is equally essential to achieve optimal results. Additionally, our extensive knowledge in material science, physics, and hydrology enhances our capabilities in providing comprehensive solutions.


Cooperation is important

Our engineering skills are a key strength that enables us to deliver high-quality installations at your site. It starts with you presenting us with you specific issue or challenge. Using our expertise, we calculate and present one or more solutions tailored to your needs. These solutions can involve utilising our existing products, or developing custom installations.

In collaboration, we assess and determine the optimal solution, taking into account factors such as cost and timeframe. Once the best course of action is agreed upon, we move forward with production and/or development to bring the solution to life.


Mounting and assembly

We take pride in providing comprehensive solutions that encompass assembly and mounting services. With our extensive experience in mounting work within watercourses, rivers, and reservoirs, even in extreme weather conditions, safety is always our top priority. Prior to commencing any work, we ensure that safe-work instructions are provided, and toolbox talks are conducted throughout the project.

While some customers prefer to handle the mountings on site with their own staff, we fully support their decision. We are always accessible for assistance and support through phone or email.

Inspection of products for hydropower and safety

Inspection and maintenance

Inspections and maintenance are essential to ensure a long lifetime and high performance of our products. We can enter inspection and maintenance contracts worldwide.

Together we find the right solutions to best maintain your installations, tailored for your current needs.

Today, we do much more than that. We have established ourselves in many markets and excelled in various fields and production technologies. Our own products dominate our deliveries, while we remain an important partner and manufacturer of our customers’ products. We are a leading player in our areas of expertise. Over the years, several companies have been merged and integrated into PartnerPlast. Our subsidiary, Molstad Modell og Form AS, will initially change its name to Ovun Innlandet AS, and will also be merged into Ovun in the near future. We are doing this to create maximum efficiency and a unity – “One Company” – for all our stakeholders. In order for the name to represent what we stand for, we feel the need to change the company name. A name change…
