Oil & gas manufacturing
First In Service builds certified process equipment for oil and gas: pressure vessels, tanks, piping modules and skids designed to EN 13445 and PED 2014/68/EU, from 200 kg to 25,000 kg and up to 25 × 5 × 5 m. Materials cover carbon steel, stainless, duplex and super duplex, inspected by VT, PT, MT and RT.
First In Service manufactures PED 2014/68/EU certified pressure equipment and process modules in Tallinn, Estonia: pressure vessels, tanks, piping modules and skids in carbon steel, stainless, duplex and super duplex, fabricated to 160 tonnes and machined to ±0.02 mm. Every delivery ships with a complete Manufacturing Data Record: EN 10204 3.1 material certificates (3.2 on request), NDT reports (VT, PT, MT, UT) by certified partners, dimensional logs and pressure test protocols. NORSOK M-501 and C5-M coating is applied in-house.
Equipment we manufacture for oil & gas.
If your equipment is not listed, ask anyway. The envelope and the documentation scope decide fit, not the part name.

In process industries, the paperwork is part of the pressure boundary.
A pressure vessel without a complete documentation trail is worse than late: it legally cannot enter service. Missing 3.1 certificates, incomplete NDT records or an unclear PED conformity route stop a commissioning schedule as surely as a failed hydrotest. And when a subcontractor discovers the gap late, it becomes your gap. In oil & gas, the suppliers worth keeping are the ones who treat the Manufacturing Data Record as part of the product.
PED-certified production with the MDR built as we build.
We manufacture pressure vessels, tanks, piping modules, and process skids to PED 2014/68/EU in our 18,000 m² Tallinn facility. Material traceability starts at plate receipt and follows every heat number through cutting, welding, NDT, and pressure testing, so the documentation package is complete the day the component is, not weeks after.
Typical scope

Materials
Standards & compliance
One site, one contract, one accountable counterparty.
With fabrication, machining, surface treatment, assembly and FAT under one roof, there are no handovers between suppliers where schedules slip and traceability gets lost. EU origin simplifies customs and content requirements for European projects, and port access 20 km away keeps oversized module transport off congested corridors.

Questions oil & gas buyers ask
Can First In Service manufacture PED-certified pressure equipment?
Yes. Pressure vessels, tanks, piping modules, and skids to PED 2014/68/EU, with the conformity assessment route defined by the equipment category.
What documentation ships with oil & gas components?
A complete Manufacturing Data Record: EN 10204 3.1 material certificates (3.2 on request), NDT reports (VT, PT, MT, UT via certified partners), dimensional logs, and pressure test protocols.
What materials do you process for oil & gas service?
Carbon steel, stainless steel, duplex and super duplex, selected to suit the service conditions, with full heat-number traceability from plate to finished component.
Do you provide NORSOK-compliant surface treatment?
Yes. Automated shot-blasting and coating systems to NORSOK M-501 and C5-M for offshore and coastal installations.
Can you handle both fabrication and machining in one contract?
Yes, that is the point of our model. Fabrication, precision machining, surface treatment and assembly with FAT happen in one Tallinn facility under one contract and one quality system.
