Norwegian aquaculture technology · Delivered in Asia

Fish farming as a service, built for Asia

Fiskevelferd develops patent-pending submersible pens and renewable-energy feed platforms in Norway. Together with our partner TP Dynamic Solutions in Busan, we deliver them to Asian fish farmers — as equipment, or as a complete service with no upfront investment.

Havbruk as a Service

Modern farming technology without the capital barrier

Most fish farms in Asia run on diesel-powered barges and manual feeding. Replacing them normally means heavy upfront investment. HaaS changes the model: we install, power, and service distributed feed platforms — and farmers pay for what they use.

Renewable, not diesel

Each platform is powered by wind and solar with an energy surplus — cutting fuel logistics, emissions, and noise at the farm.

Gravity does the feeding

Feed is distributed by gravity through water-borne lines instead of energy-hungry pneumatic blowers — fewer moving parts, gentler on the feed, and close to zero energy per tonne.

Delivered as a service

We own, install, and maintain the platforms. Farmers get modern feeding infrastructure with no capex, predictable costs, and a partner responsible for uptime.

Technology

Patent-pending systems, engineered offshore-grade

Floating Feed Platform

A compact, moored platform that stores and distributes feed to nearby pens. Designed for distributed deployment: several small units close to the fish instead of one large barge far away.

  • Wind and solar powered, with surplus energy available for service operations
  • Gravity-fed, water-borne feed distribution — near-zero energy per tonne fed
  • Conical feed tank and moonpool pontoon for gentle, reliable feed handling
  • Small footprint, installed and serviced by ordinary workboats

All benefits — Floating Feed Platform
ArgumentDescriptionEffect
EnergyGravity-fed distribution replaces pneumatic blowersNear-zero feeding energy
EmissionsWind and solar replace diesel generatorsNo fuel logistics, no local emissions
Feed qualityNo high-speed air transport of pelletsLess feed dust and breakage
NoiseNo compressors or generators running at the farmCalmer fish, better neighbour relations
DistanceDistributed units sit close to the pens they feedShort lines, precise feeding
InvestmentOffered as a service (HaaS)No capex barrier for the farmer
MaintenanceFew moving parts by designHigh uptime, low service cost
InstallationCompact units handled by ordinary workboatsFast, low-cost deployment

Submersible Pen

A tension-moored pen built around a central column, able to operate submerged below the turbulent and parasite-rich surface layer — and to ride out typhoons and rough seas where surface pens cannot.

  • Operates below the surface layer where lice and many parasites concentrate
  • Submersion protects fish and structure in typhoons and extreme weather
  • Opens new farming areas: exposed sites, inland seas, and under ice
  • Air pocket in the upper collar gives the fish permanent access to air

All benefits — Submersible Pen
ArgumentDescriptionEffect
Sea licePen operates below the surface layer where lice concentrateLower cost, faster growth, lower mortality
Toxic algaeSubmersion below algae blooms, as with liceAvoids loss of entire stock during an attack
Rough seasThe buoyancy body is the column itself — submerged and tension-moored to the seabedMinimal motions in high seas and typhoons
TemperatureDepth is chosen for optimal water temperatureFaster growth
CrowdingCrowding by elevating the pen, not by nets and forceGentle handling, lower mortality
Air pocketUpper collar holds an air pocketFish keep permanent access to air
DisturbancesStable, well-tensioned pen; no equipment lowered into itBetter welfare and growth
EscapeNo contact between vessels and penReduced escape risk
BiofoulingLess fouling at depthLess net cleaning
Structural failureSubmersion reduces loads in extreme weatherLower risk, lower insurance premium
IceFully submerged operation under thick iceOpens inland and cold-climate markets
HSENo manual operations at the pen edgeFewer personal injuries
Other speciesSuited to bottom fish such as cod and halibutExpanded market
InstallationInstalled using smaller service vesselsLow cost
Net changeNet change with direct transfer of fishLow cost, gentle handling

In development: juvenile health systems

For warm-water species such as barramundi and grouper, skin parasites in the juvenile stage are among the largest loss drivers. We are developing a chemical-free freshwater treatment system for marine juveniles, designed for gentle handling and integration with our pen systems.

Concept stage — details available to qualified partners under NDA.

"The submersible solution may open up more areas suitable for fish farming — including inland seas and under ice."
