A separator or process vessel tender is governed by the design code the buyer names, and that single choice changes who can even bid. ASME VIII Division 1 is one fabrication and documentation regime; Division 2 is a more demanding one with stricter analysis and inspection; the European PED adds its own conformity route and notified-body involvement. Layer in separator internals designed to API 12J, and the tender becomes a test of whether your shop holds the right code stamp and can produce the required documentation, before any discussion of price.
What the Code Choice Changes
Division 2 demands design-by-analysis, tighter tolerances, and more extensive NDT and documentation than Division 1, which raises cost and excludes shops set up only for Division 1. PED requires CE marking through a notified body for the European market. API 12J governs the separation performance and internals sizing the buyer expects. The code and class together set the material traceability, the weld procedures, the inspection regime, and the data book. A shop that cannot stamp the named code is out at the technical gate.
Why Code Requirements Get Underestimated
The headline of a vessel tender is the size and the duty, which look manageable. The governing code and division sit in the mechanical design basis, the notified-body requirement in the commercial conditions for European buyers, and the API 12J internals expectation in the process datasheet. A fabricator can size the vessel and start costing before confirming the tender demands Division 2 or PED conformity it is not set up to deliver. The realization arrives too late to assemble the capability.
How an AI Bid Response Agent Confirms the Code
An AI bid response agent reads the mechanical design basis, the process datasheet, and the commercial conditions together, and surfaces the governing code, division, PED or notified-body requirement, and the API 12J internals expectation against what your shop holds. It flags a Division 2 or PED requirement you are not certified for before you invest in the bid. You confirm you can stamp and document the vessel the buyer specified, on the first read.
