Sea-Tek

What Sea-Tek does

Sea-Tek AS is a privately held Norwegian maritime equipment and service company founded in 1976 and headquartered in Spydeberg, Norway. The business is organized into three divisions: Sea-Tek Power (supply of engines and waterjet units), Sea-Tek Service (maintenance and repair of workboats including propulsion systems, stabilization systems, GRP repair, welding, fabrication, and vessel conversions), and Sea-Tek Supply (import and distribution of maritime equipment). It serves commercial vessels, professional maritime operations, and workboat operators — primarily in Norway with stated global service delivery capability — through direct sales, a small technical team (~12 personnel), and a web shop.

The product portfolio is anchored by Kamewa waterjet propulsion systems (FF, A5, and S-3/CA series) sourced under authorization from Kongsberg Maritime, and Seakeeper gyro stabilizers capable of reducing vessel rolling by up to 95%. Additional distributed lines include Molabo 48V touch-safe electric drive systems for hybrid propulsion, Garmin marine electronics, Marol steering and autopilot systems, Kobelt bronze and stainless-steel components, Hydrotab trim systems, Gali air starters, and proprietary Sea-Tek Teflon low-friction cables. The company also sells used and refurbished Iveco N67 marine engines (priced at 125,000–280,000 NOK) and used Ultra Jet 305 waterjets (120,000 NOK per unit) via its web shop.

Revenue is generated through three streams: hardware sales of engines, waterjets, and distributed equipment; professional services including maintenance, repair, installation, and refit work; and distribution margin on partner products. Pricing is unit-based for hardware and project/engagement-based for services, with no subscription or recurring software model. Sea-Tek holds NS-EN ISO 9001:2015 quality certification, is privately owned with no disclosed parent or institutional investors, has no subsidiaries, and has not completed any disclosed funding rounds, acquisitions, or restructuring events.

Scale indicators3 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Wärtsilä: Global marine engine, propulsion, and lifecycle services provider with direct service networks across Europe. Comparable to Sea-Tek in marine engine service and spare parts but at vastly greater scale and broader product scope.
• MAN Energy Solutions: Supplies marine diesel and dual-fuel engines plus aftersales service worldwide. Comparable to Sea-Tek's propulsion supply and MRO business for commercial vessels.
• Volvo Penta: Marine and industrial engine OEM with established European dealer/service networks for engine supply, servicing, and parts — directly comparable to Sea-Tek's Iveco engine supply and workboat service offering.
• ZF Marine: Supplies marine propulsion systems (drives, transmissions, propellers) and supports global service for commercial and recreational vessels. Overlaps with Sea-Tek's propulsion integration and MRO focus.
• Kongsberg Maritime: Parent of the Kamewa waterjet brand that Sea-Tek distributes. Kongsberg Maritime provides marine propulsion, automation, and navigation systems globally and is both Sea-Tek's key supplier and a broader competitor in propulsion integration and ship systems.
• Caterpillar Marine: Global marine engine OEM with extensive dealer/service network offering engine sales, parts, and service for commercial and workboat applications — same core activity as Sea-Tek Power/Service.

Others

• Seakeeper: Manufacturer of marine gyro stabilizers that Sea-Tek distributes and installs. Sea-Tek is a channel partner; comparing them highlights Sea-Tek's role as installation/service layer versus the product OEM.

Direct peers

• MarineDiesel Scandinavia: Niche supplier of marine diesel engines, components, and service for workboats and commercial vessels in Scandinavia. Closely matches Sea-Tek's engine supply and service business in the Nordic region.
• Brunswick Commercial & Government Products: Boat dealer and marine equipment/services provider offering propulsion, electronics, and service for commercial and workboat markets. Directly comparable to Sea-Tek's role as a multi-brand marine equipment supplier and servicer.

Regional players

• Hydema: Norwegian marine systems provider offering propulsion, deck machinery, and lifecycle service for commercial vessels — a regional Nordic peer to Sea-Tek in marine MRO and equipment integration.
