Norwegian water treatment specialist Nordic Clean Pumps (NCP) has supplied oxygenation technology to support FishGLOBE’s closed aquaculture facilities operating in the Red Sea, where high water temperatures create challenging conditions for fish farming.
The system is designed to ensure stable oxygen levels, consistent water quality and controlled environmental parameters in FishGLOBE’s closed tanks, helping to reduce biological stress and support fish health in warm-water operations.
FishGLOBE’s two closed containment units – with volumes of 3,500 m³ and 10,000 m³ – are being deployed for the production of Seriola species as part of a project for the end customer Neom in Saudi Arabia. In the Red Sea, water temperatures can reach 30°C, significantly reducing the amount of dissolved oxygen available compared with colder waters.
“At temperatures like these, oxygen availability is roughly half of what it is in Norwegian waters,” the companies said, highlighting the need for high-performance oxygenation and water treatment solutions.
Technology tested under Norwegian conditions
Nordic Clean Pumps was approached by FishGLOBE in early 2025 to address the oxygenation challenge. Several systems were tested at FishGLOBE’s salmon facility in Lysefjorden, Norway, where NCP’s patented Total Gas Control (TGC) system was selected based on its performance.
According to the companies, the TGC system demonstrated high efficiency in dissolving oxygen while also stripping excess nitrogen, distributing oxygen evenly throughout the water column and avoiding the formation of microbubbles inside the tanks – a factor linked to fish stress and health issues.
The TGC system is designed for high-capacity operation under extreme conditions and offers modular scalability across different production phases. It is compatible with both land-based and sea-based closed containment systems.
Installed and preparing for operation
The two FishGLOBE units have now been installed in the Red Sea, with power supply and supporting infrastructure currently being finalised. Under a separate operating agreement, FishGLOBE will manage service, maintenance and technology operations for the closed aquaculture facilities on behalf of the buyer.
The project forms part of broader efforts to adapt closed-containment aquaculture technologies to warmer marine environments, where oxygen management, water quality and energy efficiency are critical to operational viability.
