McDermott procures valves through project-specific Material Requisitions (MRs) from Houston (LNG, USA projects), Mumbai (Middle East and India projects), and Kuala Lumpur (Asia-Pacific projects). McDermott's Mumbai office sources significantly from Indian manufacturers for Gulf and Asian EPC projects. Supplier qualification requires ISO 9001, API product licences (API 6D, 526, 609 as applicable), and completion of McDermott's Vendor Qualification Questionnaire (VQQ) — full process safety documentation (PSR) is required for ESD valve assemblies.
