What industries has First In Service delivered to?

Marine, offshore and subsea, oil & gas, defence, energy and rotating equipment, mining and machine building, and pulp & paper — over 15 industries in total.

Can First In Service provide client references?

Most delivery programs run under NDAs with Nordic and European OEMs, so client names are protected. Anonymized program scope — sector, component type, materials, documentation, duration — can be discussed in a direct conversation.

What proof of quality does First In Service offer?

Proof labeled by verifiability: independently checkable certifications and facility facts, documented Manufacturing Data Records shipped with every delivery, and the publicly documented EU-funded Planlogi digitalization project.

Does First In Service work with classification societies?

Yes — DNV, Lloyd's Register, Bureau Veritas, and RINA, with the survey and documentation scope defined per project.

Industry References & Project Portfolio

First In Service OÜ delivers precision-manufactured components and assemblies for the most demanding industrial applications. Below are the industries we serve, with representative project examples.

Oil & Gas / Process Equipment

We manufacture PED-certified pressure vessels, tanks, piping modules, and skids for the oil and gas industry. Our fabrication capabilities cover carbon steel, stainless steel, duplex, and super duplex materials with full material traceability and NDT documentation (VT, PT, MT, UT). Typical projects include pressure vessels up to 35 meters in length, piping modules with complex geometries, and complete skid-mounted process units. All products comply with PED (Pressure Equipment Directive) and international safety standards. Surface treatment to NORSOK M-501 and C5-M anti-corrosion standards is available for offshore and subsea applications.

Rotating Equipment & Energy

Custom-manufactured components for energy and power generation sectors including dynamically balanced impellers, casings, rotors, and shaft systems. We machine components up to Ø 2,800 mm diameter on our vertical turning lathes and boring mills. Shaft turning capabilities extend to 3,250 mm length on the PUMA 700LY II horizontal lathe. All rotating components undergo dynamic balancing to ensure vibration-free operation. Materials include carbon steel, stainless steel, and speciality alloys. Tolerances down to ±0.02 mm on critical bearing surfaces and seal areas.

Marine, Offshore & Subsea

We machine and fabricate components built to withstand extreme pressures and corrosive marine conditions. Our marine portfolio includes azipod components, thruster housings, propeller shafts, rudder stocks, and structural elements for offshore platforms. We work with marine-grade materials including duplex, super duplex, CuNi alloys, and classification society approved steels. Our products meet DNV, Lloyd's, Bureau Veritas, and RINA classification requirements. Complete surface treatment systems ensure long-term corrosion protection in the harshest maritime environments.

Defence

Precision manufacturing of highly regulated, mission-critical components for the defence sector. Full material traceability from raw stock to finished product. Strict quality control with full documentation packages. Our capabilities cover precision CNC machining, certified welding, and complex assembly operations meeting defence industry specifications. All work performed under controlled conditions with restricted access as required.

Mining & Machine Building

Heavy-duty machine building assemblies engineered for extreme conditions in the mining sector. We fabricate and machine components using wear-resistant materials including hardened steels and abrasion-resistant alloys. Typical projects include crusher components, conveyor drive units, screening machine frames, and complete machine assemblies weighing up to 160 tonnes. Our 18,000 m² workshop with overhead cranes and heavy lifting capacity enables efficient handling of the largest mining equipment components.

Pulp & Paper Machinery

Precision spare parts and critical processing components for continuous production environments in the pulp and paper industry. We understand that unplanned downtime costs thousands of euros per hour, which is why we prioritize rapid manufacturing turnaround for critical replacement parts. Our CNC machining capabilities handle roller shafts, headbox components, dryer cylinders, and other precision parts with tolerances that ensure seamless fit and immediate installation.

Proven Expertise Across Demanding Industries

Proof, in writing

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.

VERIFIABLE

Certifications & audited quality systems

ISO 9001, ISO 14001, EN 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.

VERIFIABLE

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.

DOCUMENTED

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.

VERIFIABLE

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.

UNDER NDA

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.
