Steel Detailing for Qatar Gas & Industrial Projects
Tekla models, fabrication drawings and material take-offs for Qatar's gas, LNG and industrial steelwork, from a senior team with Dolphin Energy project experience, two hours ahead of Qatar time.
Detailing Support for Qatar's Gas Sector
PetroHill supports fabricators and EPC contractors delivering steel and concrete structures for Qatar's gas, LNG, petrochemical and industrial projects. We work from Lahore, two hours ahead of Arabia Standard Time, so our working day covers the whole Qatar business day.
Qatar's energy work is concentrated in a few large industrial cities, Ras Laffan and Mesaieed above all, where expansion trains, utilities and brownfield tie-ins generate large volumes of pipe rack, platform, shelter and equipment-support steel. Fabricators in Doha's industrial areas and the yards serving these sites need detailing capacity that can follow a long, specification-driven document hierarchy without slowing down.
Our senior team's Qatar experience comes from the Dolphin Energy project, which processes Qatari gas for export to the UAE. In prior engagements they produced detailed engineering drawings, PDS and FrameWorks Plus models, model reviews and material take-offs. We apply that model-based discipline to Tekla packages today: coordinated models, consistent numbering and quantities that reconcile with the drawings at every revision.
On QatarEnergy-operated and affiliated projects, the operator's engineering standards and the project specification govern. We detail to them as issued, alongside the AISC or Eurocode design basis your engineer has specified, and we do not claim operator approval; vendor qualification stays with the EPC and the fabricator.

Standards & Specifications
QatarEnergy engineering standards, EPC procedures and the project specification govern where they apply; we detail to them as supplied and flag conflicts with the general codes for the engineer to resolve. Working to a standard is not a claim of approval or certification.
The scope of work records the applicable standards and editions for each package. A reference to a standard does not imply design verification or certification.

Common Questions
Related services
Do you have an office in Qatar?
No. We work remotely from our office in Lahore, two hours ahead of Qatar. Models, drawings and comments move through your document control system or an agreed transfer method, and calls are held in Qatar working hours.
Can you work to QatarEnergy standards and project specifications?
Yes. We detail to the operator standards, EPC procedures and project specifications issued with each package, and record which document governs each requirement. We do not claim QatarEnergy approval; vendor qualification remains with the EPC and the fabricator.
Can you produce material take-offs for procurement?
Yes. Take-offs come from the detailing model and are tied to the drawing revision they were taken from, with units, inclusions and exclusions stated, so procurement quantities can be reconciled as the design develops.
How quickly will we receive a quote?
We reply to quote requests within 24 hours (GCC working day). Send drawings or a scope summary with the deliverables, standards and target dates you have; where inputs are incomplete we list the assumptions we priced and the questions to close.
Can we start with a small trial package?
Yes. Our pilot is one assembly or a 5–10 t package, at a fixed price, delivered in 5 working days from receipt of complete inputs. It lets you check our model, drawing standard and checking on your own project before committing a larger package. NDA on request.
Send Your Drawings
We reply within 24 hours (GCC working day). A scope summary is enough to start; NDA on request.
