Marine, Offshore & Subsea Manufacturing
Propulsion components, offshore structures, and subsea elements — machined to ±0.02 mm, coated to NORSOK M-501, 20 km from the quay.
First In Service manufactures marine, offshore and subsea components in Tallinn, Estonia: welded structures up to 35 × 7 × 7 metres and 160 tonnes, and machined parts up to Ø 2,800 mm and 13,000 mm in length to ±0.02 mm. Surface treatment to NORSOK M-501 and C5-M is applied in-house with film thickness logged per layer. Certified to EN 3834-2, EN 1090-2 and PED 2014/68/EU, with classification society scope agreed per project (DNV, Lloyd’s Register, Bureau Veritas, RINA). Muuga Harbour is 20 km away by direct heavy-haul road.
Parts we manufacture for marine and offshore.
If your component is not listed, it is still worth asking — the envelope, materials and documentation matter more than the part name.
Salt water does not forgive shortcuts.
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.
One integrated site, from plate to classed component.
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 tonnes, and apply NORSOK M-501 / C5-M coating systems in-house. Surveyors visit one address.
Typical scope
Relevant equipment
Materials
Standards & class
160 tonnes, 20 km to the ship.
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.
Questions marine buyers ask
Can First In Service manufacture components for classed vessels?
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.
What marine propulsion components can you produce?
Azipod parts, thruster housings, propeller shafts, rudder components, and structural elements — machined to ±0.02 mm where the fit demands it.
What corrosion protection do you provide for offshore environments?
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.
What materials do you work with for marine and subsea applications?
Stainless steel, duplex and super duplex, marine-grade steels, and CuNi alloys, with full EN 10204 3.1/3.2 material traceability.
How large can marine structures be?
Up to 35×7×7 metres and 160 tonnes, with heavy-haul road access to Muuga Harbour 20 km away, and ro-ro shipping for oversized loads.
Same facility. Different proof per sector.
