Marine, Offshore & Subsea Manufacturing
First In Service OÜ manufactures marine propulsion components, offshore structures, and subsea elements in Tallinn, Estonia — azipod parts, thruster housings, and propeller shafts to classification society requirements, with NORSOK M-501 surface treatment and port access 20 km away.
Propulsion components, offshore structures, and subsea elements — machined to ±0.02 mm, coated to NORSOK M-501, 20 km from the quay.
A thruster housing that fails in service means a vessel off charter and a dry-dock bill that dwarfs the component's price. A coating system that underperforms in the splash zone means corrosion claims years before scheduled maintenance. Marine and offshore procurement is not about finding the cheapest machining hour — it is about eliminating the supplier as a source of risk. That means classification society compliance, materials that match the certificate that accompanies them, and coating systems tested for the actual service environment, not the brochure.
Fabrication, machining, surface treatment, and assembly happen in one 18,000 m² facility in Tallinn — one audit covers the entire production chain, and one contract carries single-point accountability. We machine propulsion components to ±0.02 mm, fabricate structures to 35×7×7 m and 160 tons, and apply NORSOK M-501 / C5-M coating systems in-house. Surveyors visit one address.
Our facility sits 20 km from Muuga Harbour and 60 km from Paldiski Port, with direct heavy-haul road access and no urban restrictions on oversized transport. For marine components, the distance between the machine shop and the quay is not a detail — it is schedule risk, handling risk, and cost, and ours is among the shortest in Northern Europe.
Yes. We manufacture to classification society requirements including DNV, Lloyd's Register, Bureau Veritas, and RINA, with the survey and documentation scope defined per project.
Azipod parts, thruster housings, propeller shafts, rudder components, and structural elements — machined to ±0.02 mm where the fit demands it.
Complete surface treatment from automated shot-blasting to coating systems compliant with NORSOK M-501 and C5-M, the standards written for splash-zone and subsea service.
Stainless steel, duplex and super duplex, marine-grade steels, and CuNi alloys, with full EN 10204 3.1/3.2 material traceability.
Up to 35×7×7 metres and 160 tons, with heavy-haul road access to Muuga Harbour 20 km away, and ro-ro shipping for oversized loads.
