What Sea Tech ltd does

Sea Tech Ltd (KB "Sea Tech", ООО "Си Тех") is a Russian shipbuilding design and engineering bureau headquartered in Nizhny Novgorod with a subdivision in Gorodets. Founded in 1998 with Norwegian co-founders from Steelcad Consultants A/S, the firm carries direct engineering lineage from TSKB SPK named after R.E. Alexeev, the founder of Soviet/Russian hydrofoil shipbuilding. With only nine employees, Sea Tech specializes in the design of hydrofoils, air-cushion vehicles, and displacement vessels, and has developed a proprietary CAD/software suite — Sea Solution, Sea Hydro, Sea Solid, Sea Hull, Sea Lines, and Sea Motion — that holds ROSAPO certificates and is licensed to universities and shipbuilders. The firm's designs span passenger hydrofoils (Meteor 03830, serial-produced at Zelenodolsk Plant), fishing vessels across 40+ hulls over 25+ years, high-speed craft (HSC150B, HSC200), floating docks, ferries, private yachts (SeaStyle brand), and modular floating complexes, with digital twin and CFD (FlowVision) capabilities integrated into the design workflow.

Sea Tech's business model combines project-based ship design contracts, engineering support fees tied to serial production milestones (such as the 5th and 6th Meteor 03830 hulls delivered in July 2025), and software licensing for the Sea Solution suite. The firm serves a concentrated Russian customer base of government transport operators (AO Fleet RT, Primorsky Krai Ministry of Transport via GTLK), shipbuilders (Zelenodolsk Plant, AO Pella, PAO SSK), commercial fishing operators, and private yacht buyers via the SeaStyle subsidiary. International work exists via Norwegian heritage, Polish salmon-industry collaborations, Turkish Naval Yachts, and Dutch/German distribution channels, though the core revenue base is domestic Russian. Recognition includes the Golden Mercury national award, an RKO Recognition Certificate valid through 2028, Russian Maritime Register certification for Sea Hydro, and a 2nd place finish at Maritime Olympus 2025 for the HSC150B design.

Scale indicators5 records

Recent moves7 records

Expansion highlights6 records

Others

• Cadmatic: Finnish shipbuilding CAD/CAM software vendor whose Marine Solution platform is integrated with Sea Tech's in-house Sea Solution suite. Comparable as a maritime-focused CAD vendor competing for the same shipyard IT budgets.
• AVEVA (E3D / Marine): Global industrial software vendor with marine/naval architecture solutions (formerly AVEVA Marine). Constrains the addressable market for Sea Tech's Sea Solution, Sea Hydro, and Sea Solid software products.

Direct peers

• TSKB SPK named after R.E. Alexeev: Historical Soviet/Russian hydrofoil design bureau (now part of USC) that originally designed the Meteor-class hydrofoil. Sea Tech explicitly draws staff heritage from this bureau and competes in the same hydrofoil design category for Russian inland waterway operators.
• Skipsteknisk AS: Norwegian naval architecture firm specializing in fishing vessel, offshore, and research vessel design. Skipsteknisk is named in Sea Tech's data as the designer of G.O. SARS (the canonical Sea Tech hull theory collaboration), and the two firms share a fishing vessel design heritage — comparable in scope, customer base, and design disciplines.
• Brødrene Aa: Norwegian builder/designer of high-speed aluminum catamarans and passenger vessels. Operates in the same high-speed light-craft segment as Sea Tech's HSC150B and HSC200 catamarans, with comparable end-customer profile in coastal and ferry operators.
• Baglietto / Naval Yachts (Turkey): Turkish yacht builder that is named in Sea Tech's data as a partner for the Bering yacht series. Comparable as a builder of ocean-going motor yachts in the same size band (50-80ft) where Sea Tech provides RKD and interior design services.

Broad incumbents

• Incats Tasmania: Australian high-speed catamaran shipbuilder known for global ferry and HSC operators. Far larger than Sea Tech, but directly competes in the high-speed passenger vessel segment that Sea Tech's hydrofoil/catamaran portfolio addresses.
• Austal Ships: Australian high-speed vessel and ferry designer/builder serving defense and commercial markets. Comparable in delivering high-speed passenger and fast crew transfer vessels, but at considerably larger scale and broader geographic reach.
• Damen Shipyards Group: Dutch shipbuilding group with broad vessel portfolio including fast crew suppliers, workboats, and patrol vessels. Overlaps with Sea Tech's patrol, workboat, and hydrofoil segments as a multinational incumbent with deeper engineering bench.
• Wärtsilä Marine Solutions: Finnish marine engineering and ship power solution provider. Comparable as a marine engineering powerhouse whose ship design and efficiency solutions compete with Sea Tech's hydrodynamics and propulsion-aware design services in the broader marine engineering market.
