Design & Engineering
Design and Engineering
Our engineering services cover hydraulic and structural calculations, material selection, detailed fabrication drawings, welding requirements, protective-coating specifications, installation planning and preparation of operation and maintenance documentation.
Equipment can be designed and supplied in accordance with applicable international standards, including ISO, EN, DIN, AWS and ASME, together with the employer’s technical specifications.
All equipment is delivered according to approved project specifications, quality plans and inspection procedures. Quality-control activities may include material traceability, welding qualification, dimensional inspection, non-destructive testing, trial assembly, coating inspection and factory acceptance testing.
Installation
metrading provides installation supervision, mechanical erection, embedded-part alignment, field welding, hydraulic and electrical integration, dry and wet testing, load testing, commissioning and operator training.
From individual equipment packages to integrated hydromechanical systems, Gulf Supply Solution provides complete installation and commissioning support.
