How they buy
Across the oil, gas & petrochemicals notices we currently hold for Thailand, the most common form is the open tender or invitation to bid. Each has its own rules — see RFP, RFQ and EOI compared and tendering procedures explained.
What qualifies you
Oil and gas procurement is dominated by state-owned and listed operators buying through their own portals rather than general government platforms. Work splits broadly into capital projects (pipeline laying, station construction, plant upgrades), operations and maintenance contracts, and equipment supply. Expect stringent safety and HSE prequalification, vendor registration ahead of bidding, and technical approvals for materials such as MDPE and steel line pipe. Contracts frequently run for several years with price-adjustment clauses tied to input indices, so read the escalation provisions before pricing.
