Standards, decoded

What each standard means for your order.

Procurement teams increasingly search by standard rather than by service, because the standard is what the audit checks. Here is what each of ours covers and what it changes in the documentation you receive.

EN 1090-2 (execution of steel structures): defines execution classes (EXC1–EXC4) for structural steelwork placed on the European market — welding requirements, tolerances, inspection and CE marking route
EN ISO 3834-2 (comprehensive welding quality requirements): the highest of the three EN 3834 levels — covers weld procedure qualification (WPS/WPQR), welder certification, equipment control and traceability
PED 2014/68/EU (Pressure Equipment Directive): governs vessels, tanks, piping and skids above 0.5 bar — the conformity assessment route follows from the equipment category
EN 10204 3.1 and 3.2 (material certificates): 3.1 is issued by the manufacturer’s own authorised inspection; 3.2 is countersigned by an independent inspector or notified body — specify which you need at RFQ stage
NORSOK M-501 (surface preparation and coating): the Norwegian offshore standard specifying coating systems, surface preparation grade, application conditions and per-layer film thickness records
ISO 9001 / ISO 14001: quality and environmental management systems — necessary, but on their own not evidence of welding competence
NDT (VT, PT, MT, UT): performed by certified partners — independent verification rather than self-inspection

FAQ

Questions buyers ask

What certifications does First In Service hold?

ISO 9001 (quality management), ISO 14001 (environmental management), EN ISO 3834-2 (welding quality), EN 1090-2 (structural steel execution), and PED 2014/68/EU (pressure equipment).

What does EN ISO 3834-2 certification cover?

Comprehensive quality requirements for fusion welding of metallic materials — the highest of the three EN 3834 levels, covering welding procedures, personnel qualification, and process control.

What does EN 1090-2 certification cover?

Execution of steel structures and aluminium structures — the technical requirements for structural steelwork placed on the European market.

Is First In Service PED certified?

Yes. Pressure equipment is manufactured to PED 2014/68/EU, with the conformity assessment route defined by the equipment category.

How is NDT handled at First In Service?

Non-destructive testing (VT, PT, MT, UT) is performed by certified partners, giving independent verification of every critical weld rather than in-house self-inspection.

Can the certificates be verified independently?

Yes. Certificates are published on this page with issuing bodies and validity dates, and can be checked against the certification registries directly.

In brief

160 tonnes. 35 metres. 20 km to the ship. Heavy fabrication, precision machining and mechanical assembly under a single contract. One supplier is responsible for the finished geometry and for the documentation that proves it.
