Landbasert oppdrettsanlegg i Hirtshals med RAS-teknologi

Landbasert lakseoppdrett med RAS

The project involves the construction of a land-based salmon farming facility in Hirtshals that will utilize advanced Recirculating Aquaculture Systems (RAS) technology for the fish on-growing phase. The overall planned capacity of the facility is up to 10,000 tons of salmon, with a phased, modular build-out approach. This allows the production to be scaled efficiently over time, adapting to market demands and company strategy. The facility aims to integrate technology, biology, and sustainability to showcase how circular economy principles and energy efficiency can be implemented at a large scale in modern fish farming.

Optiras leverer modulær RAS-teknologi

Optiras was selected as the primary supplier for the RAS technology following an extensive evaluation process lasting nearly ten months. Their patented OptiRAS module technology features high water turnover rates, automated control systems, and integrated water treatment to maintain high water quality and ensure fish welfare. The modules are delivered as self-contained units that have been pre-produced and tested, allowing for rapid, cost-effective installation and reducing both biological and technical operational risks. In addition, Assentoft Aqua has been chosen to supply equipment for the hatchery and juvenile phases, supporting a comprehensive production chain within the facility.

Elforsyning truer prosjektets framdrift

The project is structured under the ownership of Onnest, with key shareholders including Samuel Muren and Håkon Volden each holding 45%, and Linn Indestrand owning the remaining shares. Despite the well-developed technological and operational plans, the project currently faces significant risks related to inadequate and uncertain electricity supply from the local North Jutland power grid. This unexpected challenge threatens the project's timeline and scale, with potential consequences including downsizing, postponement, or relocation to another country. The electricity supply uncertainty also hampers the ability to finalize critical contractual agreements, jeopardizing the entire development.
