The energy hub will supply the new commercial and office buildings with both heating and cooling based on seawater energy – a modern, energy-efficient solution that delivers a low carbon footprint and high operational reliability.
Our scope of delivery includes prefabricated PE pipe components, as well as installation of complete piping systems up to the heat exchangers and technical systems within the energy hub. Pipe dimensions range from 63 to 250 mm, involving complex geometry and extensive on-site adaptations.
"This is a project where we really get to use our strengths in prefabrication and on-site adaptation," says Erik Klepp, Project Engineer at Bluegreen. "The space is tight, the setup is complex, and everything has to be accurate down to the millimetre. At the same time, it’s rewarding to see how well PE performs in energy facilities like this – it provides flexibility, long service life and a corrosion-free system."
The energy hub at Horten Industrial Park is being built with seawater-based district heating and cooling. Energy is extracted from the sea, transferred via heat exchangers, and distributed to the buildings through the piping network installed by Bluegreen.
The system is designed to deliver a heating capacity of approximately 3,000 kW and a cooling capacity of around 3,400 kW. PE pipes are an ideal choice for such facilities, offering low weight, excellent formability and long service life.
“ For us, this is an important project because it combines industrial infrastructure with sustainable energy technology. It allows us to contribute robust craftsmanship designed to perform reliably for decades to come. Erik Klepp, project engineer Bluegreen
The project is being carried out in close cooperation with Assemblin, the main contractor for the energy hub’s piping systems. Bluegreen is delivering both pipe components and welding expertise, with the work executed in close coordination with other trades.
“We are very satisfied with the collaboration with Bluegreen. They are highly competent, flexible and solution-oriented. The work is carried out in parallel with other disciplines, so clear communication and structured execution are absolutely essential,” says Tom Liverud of Assemblin.
The project is scheduled for completion towards the end of 2025.
