Norwegian Greentech As

What Norwegian Greentech As does

Norwegian Greentech AS (NGT) is a Norwegian supplier of compact UV- and filter-based water treatment systems founded in 2010 and headquartered in Fosnavåg, where it assembles its equipment. The company sells primarily into three solution areas: ballast water management systems (BWTS) for shipyards and shipowners, process water treatment for offshore and land-based aquaculture, and integrated freshwater / RO packages for technical, fresh, and potable water generation. Its technology stack centers on chemical-free UV treatment combined with mechanical filtration, a proprietary dynamic UV-dosing approach that continuously adjusts intensity to flow and water quality for predictable microorganism inactivation, and an integrated control system with standard remote monitoring for diagnostics and service.

The business is B2B and sales-led, with direct engagement by a small commercial leadership (SVP Commercial Børge Gjelseth and regional sales managers) plus select channel partners such as Mistral Suisse for Italy. Revenue is generated through project-based hardware sales of newbuild and retrofit systems to shipyards, shipowners, and aquaculture operators, complemented by an aftermarket layer covering commissioning, preventive maintenance, spare parts, upgrades, and extended warranties through a global service network. NGT has accumulated more than 900-1,000 system deliveries worldwide across maritime and aquaculture, holds ISO 9001:2015 certification, and operates as a wholly-owned subsidiary of HAV Group ASA, which is listed on Euronext Growth Oslo.

The customer base spans short-sea cargo, ferries/RoPax, oil and gas, offshore wind, navy, fishing, and aquaculture — both offshore and land-based — with named enterprise clients including Nordic Halibut, Salmon Evolution (via Artec Aqua VAQ), and a KJ-led Greenland municipal program. Recent commercial activity signals geographic broadening (Greenland, Spain, the Netherlands, Italy) and vertical extension into land-based aquaculture and remote/infrastructure water supply, alongside a dedicated BWMS upgrade retrofit offering that monetizes the installed base. Pricing is not publicly disclosed and contracts are project-based, with recent awards in the NOK ~20M aggregate range and recurring 10-system batch awards.

Expansion highlights5 records

Direct peers

• Optimarin: Norwegian-headquartered ballast water treatment system specialist with a UV-based Type-approved BWTS product line. Most directly comparable to NGT in scale, geography, and core maritime focus, competing for the same shipyard and shipowner contracts.
• Coldharbour Marine: UK-based specialized BWTS provider with a focus on in-tank UV treatment technology. Competes directly with NGT in Type-approved UV-based BWTS for shipyards and shipowners across multiple vessel segments.
• BIO-UV Group: France-based supplier of UV-based ballast water treatment systems and other UV water treatment solutions. Closely comparable to NGT's chemical-free UV + filter technology approach and serves the same IMO-regulated maritime retrofit and newbuild market.
• AKVA Group: Norwegian-headquartered supplier of technology and services to the aquaculture industry, including water treatment and fish handling systems. Direct peer in the aquaculture water treatment segment where NGT supplies pressure filters and integrated systems to RAS operators.
• Ecochlor: US-based ballast water treatment system supplier using chlorine dioxide chemistry. While the technology differs from NGT's UV pathway, Ecochlor is a direct competitor in the same IMO/USCG-regulated BWTS market serving commercial vessel operators.

Broad incumbents

• Wärtsilä: Finnish marine technology major with a Water Systems / BWMS offering alongside engines, propulsion, and lifecycle services. Overlaps with NGT in maritime water treatment but is a broad incumbent serving shipyards and shipowners with comprehensive solutions.
• Xylem: Global water technology major serving utility, industrial, and commercial water markets including aquaculture and marine. Overlaps with NGT in UV-based water treatment and filtration for process water; ships at much larger scale across multiple regions.
• Veolia Water Technologies: Global water treatment solutions provider with broad portfolio including mobile/containerized water treatment and industrial process water. Adjacent to NGT's remote community and aquaculture offerings, though much broader in scope and scale.
• Alfa Laval: Global industrial equipment leader with a PureBallast BWTS product line as part of a much broader marine equipment portfolio. Competes with NGT in BWTS but operates at vastly larger scale across pumps, heat exchangers, and full marine equipment packages.

Others

• Salmon Evolution (customer/ecosystem): Norwegian land-based salmon farming operator. While not a competitor, Salmon Evolution's Phase 2 facility is a flagship reference deployment for NGT's pressure filters, illustrating the kinds of aquaculture end-customers NGT is targeting.
