Proven Expertise Across Demanding Industries
First In Service has delivered welded and machined components to marine and offshore, oil and gas, energy, defence, mining and pulp and paper customers since 2002. Delivered scope ranges from 10 kg balanced rotors to 50,000 kg marine structures, in carbon steel, stainless, duplex, super duplex, Inconel and titanium, all from one 18,000 m² site in Tallinn.
Projects by industry
Marine, offshore & subsea
We machine and fabricate parts built to withstand extreme pressures and corrosive marine conditions. From podded propulsion components to structural elements for offshore platforms. Fabrication, machining and corrosion protection are all carried out in-house — the coating is not handed to a third party.
Oil & gas / process equipment
Built to safely contain and control extreme industrial forces. We manufacture certified pressure vessels, tanks, piping modules, and skids, ensuring strict compliance with PED and international safety standards.
Rotating equipment & energy
Custom-manufactured components for the energy and power generation sectors, including dynamically balanced impellers, casings, rotors, and shaft systems, alongside critical fan and blower components.
Pulp & paper machinery
Precision spare parts and critical processing components for continuous production environments. Our priority is minimising your downtime through rapid, reliable manufacturing.
Mining & machine building
Heavy-duty machine building assemblies engineered for extreme conditions, using wear-resistant materials precision-machined to withstand high-impact, abrasive environments in the mining sector.
Defence
Precision manufacturing of highly regulated, mission-critical components for the defence sector. Full traceability, strict quality control, and compliance with defence industry specifications.
Every claim below is marked by how you can verify it.
We label our proof the way we label our welds: by what can be checked. Verifiable means you can confirm it independently today. Documented means the paperwork exists and ships with the parts. Under NDA means the client name is protected, but the scope, documentation, and duration are real and can be discussed in a call.
Certifications & audited quality systems
ISO 9001, ISO 14001, EN ISO 3834-2, EN 1090-2, and PED 2014/68/EU. Certificates are published on our certifications page with issuing bodies and validity dates — check them against the registries directly.
Facility, envelope & logistics
18,000 m² single-site workshop at Valukoja 12, Tallinn. 160-tonne lifting capacity, products up to 35×7×7 m. 20 km from Muuga Harbour, 60 km from Paldiski Port, with direct heavy-haul road access. Visit us and measure it — one audit covers the entire production chain, because everything happens in one building.
What ships with every delivery
Material certificates to EN 10204 3.1 (3.2 on request), NDT reports (VT, PT, MT, UT) performed by certified partners, dimensional inspection logs, and FAT protocols where scope requires. The Manufacturing Data Record is part of the product, not an extra.
Publicly documented project — Planlogi digital waybill integration
Full digitalization of freight documentation with the Planlogi e-waybill platform, supported by the EU NextGenerationEU Recovery Fund — a publicly funded, publicly documented project. Details on our news page.
Delivery programs — client names protected
Most of our work runs under confidentiality agreements with Nordic and European OEMs. We can discuss anonymized program scope — sector, component type, materials, documentation package, and program duration — in a direct conversation. Ask us in your RFQ.
