Woodcon Constructions  –  Oil and Gas

We Undertake the followings – Scope of Work Within Oil and Gas Projects – Fabrication and Erection of Vessels.

1. Engineering & Design Review
– Review and verification of IFC (Issued for Construction) drawings
– Compliance check with project specifications and applicable codes (e.g., ASME Section VIII, API 650, 620)
– Preparation of fabrication shop drawings and bill of materials
– Coordination with client and third-party inspection agencies for approvals

2. Material Procurement & Inspection
– Procurement of raw materials (plates, forgings, nozzles, flanges, fittings) per approved MTO
– Verification of Mill Test Certificates (MTCs)
– Positive Material Identification (PMI) as required
– Incoming material inspection (visual, dimensional, and NDT)
– Material traceability and documentation management

3. Fabrication Activities
– Plate cutting, rolling, forming (shells, heads, cones)
– Fit-up and tack welding as per approved procedures
– Welding of shell courses, heads, and nozzles (in accordance with approved WPS/PQR/WQT)
– Heat treatment (PWHT) if required by design/spec
– Surface preparation (blasting, grinding, edge prepping)
– Installation of internals (baffles, trays, demister pads, etc.)
– Attachments welding (lugs, support rings, saddles, lifting lugs)

4. Inspection & Testing
– Visual inspection and dimensional checks during each stage
– Non-Destructive Testing (RT, UT, MT, PT) as per ITP
– Hydrostatic or pneumatic pressure testing as per code
– Leak testing (helium leak test if required)
– Hardness testing and ferrite content checks (if applicable)
– Witnessing and inspection by client/third-party agencies

5. Surface Protection & Finishing
– Surface cleaning and blasting to required SA standard
– Application of primer, intermediate and final paint coats per project spec
– Holiday testing for lining/coating (if applicable)
– Insulation supports and cladding prep if required

6. Pre-Erection Activities
– Development of lifting and rigging plan
– Site logistics planning and transportation of fabricated vessel
– Foundation readiness check and anchor bolt layout verification
– Pre-erection safety checks and toolbox talks

7. Erection & Installation
– Vessel lifting, positioning, and alignment
– Grouting of base supports or saddles
– Final welding of erection joints and attachments
– Connection of vessel nozzles to piping systems
– Installation of platforms, ladders, insulation, and instruments
– Bolt torquing and flange joint makeup per specification

8. Final Testing, Handover & Documentation
– Punch list clearance
– Final inspection with client and third-party
– Preparation of As-Built drawings
– Compilation of Manufacturer’s Data Report (MDR)
– Submission of Quality Dossier including:
– NDT reports
– Pressure test certificates
– Welding logs
– Calibration certificates
– Painting reports
– Mechanical completion sign-off and handover to commissioning team
