Fabrication for the plant environment
Process plants put structural steel under demanding conditions: heavy, hot and vibrating pipe loads, wind and seismic actions on tall structures, corrosive and sometimes marine atmospheres, and owner specifications that leave no room for undocumented work.
We fabricate to the project specification – the client's own standards, PIP or NORSOK practices, AISC, EN or AS/NZS – with welding procedures and welders qualified for the job, an agreed inspection and test plan, non-destructive testing to the specified extent and a manufacturing data record for every lot. Modules and pipe racks can be pre-assembled to reduce work at site.

Steel structures for process plants
Structural and miscellaneous steel for upstream, midstream and downstream facilities.

03
Traceable materials
EN 10204 3.1 or 3.2 certificates, heat numbers carried to every piece mark.
04
Coating for the environment
Paint and galvanising systems to ISO 12944 up to CX and offshore-related systems, with DFT and adhesion records.
05
Modularisation
Pipe rack modules, process skids and pre-assembled units that move work from site to the factory.
06
Complete documentation
ITP, NDT reports, coating records and a manufacturing data record for handover.

Documentation
The manufacturing data record
What the MDR typically contains – agreed with you in the ITP.
Inspection & test plan
Before fabrication
Activities, acceptance criteria, hold and witness points.
Material certificates
EN 10204 3.1 / 3.2
With heat traceability to piece marks.
WPS, PQR & welder qualifications
Welding
Procedures and welders qualified to the specified code.
NDT reports
VT · MT · PT · UT · RT
Extent and acceptance as specified, by qualified inspectors.
Dimensional reports
Fit-up · trial assembly
Checks of modules, racks and critical interfaces.
Coating records
Surface · DFT · adhesion
Surface preparation, film thickness and adhesion tests.
Release notes
Per lot
Inspection release and third-party sign-off where required.
Packing & shipping records
Logistics
Packing lists, marking and loading records.
Contents follow the project specification and the agreed ITP.
Quality
Every weld, every heat, every coat – on record
Each project starts with an inspection and test plan agreed with you and your third-party inspector, with hold and witness points. Materials are checked against their certificates and traced by heat number; welds are made to qualified procedures by qualified welders and examined by VT, MT, PT, UT or RT to the specified extent.
Coating is applied and checked to the coating specification, and the manufacturing data record – certificates, procedures, NDT and coating reports, dimensional checks and release notes – is completed before each lot ships.
Modularisation
More work in the factory, less at site
Remote sites, short shutdown windows and high site labour costs favour modules. We fabricate and pre-assemble pipe rack modules, process module frames and equipment skids with floors, stairs and lifting points, and design transport bracing and sea-fastening interfaces with your logistics team.
Trial assembly and dimensional control in the factory make sure modules connect at site the first time.
Protection
Coating systems for the plant environment
Process plants range from C3 to CX and splash-zone exposure. We apply paint systems and hot-dip galvanising to the coating specification – ISO 12944, NORSOK M-501 or the owner's system – with surface preparation, dry-film thickness and adhesion records for every lot.

FAQ
Perguntas frequentes
Can you fabricate to our company specification?
Yes. We review your specification and its referenced standards, raise technical queries and agree any deviations before fabrication starts.
Which welding codes do you work to?

Do you allow third-party inspection?
Yes. Your inspector or a third-party agency can attend hold and witness points defined in the ITP, and EN 10204 3.2 certificates can be arranged.
Can you pre-assemble modules and pipe racks?
Yes. We fabricate and pre-assemble module frames, pipe rack modules and skids, with lifting points and transport bracing agreed with your logistics team.
Which coating systems can you apply?
Paint systems and hot-dip galvanising to ISO 12944 up to CX, NORSOK M-501 or the owner's specification, with full inspection records.
