Core offering

Flatsetsund Engineering designs, manufactures, and services patented mechanical sea lice removal systems (FLS Caligus R-Series) and complementary aquaculture equipment including on-site oxygen generation (FLS OxyGen), camera-based fish counting (FLS Calculus), AI-driven welfare monitoring (FLS Insight), biomass transport ejectors (FLS Suctus), and water aeration (FLS Aeris). Products are sold directly to salmon farming operators, well boat owners, and service vessel companies across Norway and international aquaculture markets.

Product overview

Flatsetsund Engineering (FLS) offers a unified portfolio of aquaculture technology products centered on fish welfare. The core offering includes the FLS Caligus R-Series mechanical delousing system (available in R500, R600, R670 sizes) for sea lice removal, complemented by FLS OxyGen for on-site oxygen production, FLS Calculus for fish counting and biomass calculation, and FLS Aeris for CO2 removal and water aeration. Additional products include the FLS Suctus ejektor for gentle fish transport and biomass handling. FLS Insight serves as an add-on monitoring platform that integrates with Caligus R-Series and Calculus systems, using AI and machine learning to provide welfare scoring, lice data, and operational analytics. The portfolio is unified by a focus on non-invasive, water-based solutions that prioritize fish welfare while delivering measurable operational efficiency.

Products and services

• FLS Caligus R-Series Patented mechanical sea lice removal system using low-pressure full-water flushing in rectangular chambers. Available in R500 (130-200 tph), R600 (180-300 tph), and R670 (230-350 tph). Fish remain submerged throughout treatment with delousing completed in 12-13 seconds. Designed for installation on well boats and service vessels serving salmon farms.
• FLS OxyGen Compact, modular, scalable system for local on-site oxygen production at fish farms using nanobubble technology. Produces oxygen at approximately 0.7 kW per kg, eliminating the need for liquid gas transport logistics and enabling long-term supply agreements.
• FLS Calculus Full-water camera-based fish counting and biomass calculation system using advanced computer vision. Delivers 98-100% counting accuracy under optimal conditions with real-time processing for fish sizes from 1 to 9.9 kg. Reduces fish stress via closed-water transport.
• FLS Insight AI and machine learning monitoring platform that analyzes fish welfare data collected during delousing operations. Integrates with FLS Caligus R-Series and FLS Calculus systems to deliver welfare scores, lice data, biomass measurements, and operational insights.
• FLS Suctus Patented ejektor for efficient and gentle transport of liquid and biomass in aquaculture. Uses pressure energy to create vacuum with no moving parts. Available in acid-resistant steel AISI 316 with nozzle diameters from 12mm to 350mm.
• FLS Aeris Robust water aerator for demanding aquaculture operations providing CO2 removal and oxygen enrichment, achieving up to 100% oxygen saturation while reducing CO2 levels in fish-holding water.
• Service og deler (Service & Spare Parts) Comprehensive aftermarket support offering 24/7 service hotline, technical support, spare parts ordering and delivery, and access to product documentation for installed FLS equipment.
