Project overview

Design and prefabrication of a double-skin pipeline system for diesel fuel supply to generators. The project covered complete material sourcing, spool fabrication to the isometric drawings and full preparation for installation on site.

Challenges and execution

A complex double-skin system with diameters from DN25 to DN150 required meticulous planning and stringent quality assurance:

• Fabrication sequence organised to optimise resources and keep production accurate
• Radiographic inspection for all diameters, plus full penetrant and visual testing of the welds
• Hydrostatic testing of every spool to validate pressure integrity
• A three-layer protective coating system applied to the technical standards
• Close coordination with the site teams for a smooth installation and QA/QC oversight

Key deliverables

• Prefabricated pipe spools made for the double-skin design
• Complete NDT coverage and certification of all welds
• Hydrostatic validation of each spool
• Surface preparation and coating to the technical specification
• On-site installation support, quality assurance and formal handover documentation

Outcome and impact

A fully operational fuel supply system with minimal installation risk. Meticulous fabrication and integrated site supervision secured technical compliance, system reliability and a timely commissioning.
