Chevron.
Chevron CES asks for four structured records at handover. I/O list, instrument index, SIS register, equipment list. Upstream and downstream CES conventions differ in detail but share the same document structure.
Chevron CES P&ID Extraction.
Chevron projects run against the CES family. I/O lists, instrument indexes, equipment lists, and line lists come with BPCS and SIS separation.
Primary standard: Chevron CES
Documentation expectations.
- Instrument tag conventions consistent with the CES instrumentation family
- I/O list with BPCS, SIS scope explicitly separated
- Instrument index across the full unit drawing set with tag uniqueness
- Equipment list keyed to vessels, pumps, exchangers, fired heaters, compressors
- Line list with pipe class, service, metallurgy
- SIS register filtered per IEC 61511
- Cross-unit interlock register where unit boundaries cross drawing sheets
Where Tagsight fits.
- CES-shaped tag conventions come through alongside ISA 5.1
- BPCS, SIS scope segmented onto separate Excel sheets
- Off-page connector matching across multi-page upstream, refining, and chemicals drawing sets
- Revision comparison feeds OSHA PSM MOC change records
- Direct exports to TIA Portal, Studio 5000, PLCCreator, DEXPI
- Image-based ingestion covers scanned legacy drawings
Common questions
Does Tagsight handle Chevron CES tag conventions.
Yes. CES-shaped tags come through alongside ISA 5.1. The original tag string is preserved and classified by the function letter.
Is Tagsight a Chevron-approved vendor.
Tagsight is independent. This page describes how Tagsight outputs line up with CES documentation expectations. It does not represent an approval or partnership.
Can the export support OSHA PSM MOC documentation.
Yes. Revision comparison produces an added, removed, modified diff suitable for the MOC package, with a Change Report Excel exportable to the audit trail.
How does Tagsight handle Chevron's mix of upstream and downstream documentation conventions.
Upstream tagging conventions, downstream tagging conventions, and operator-specific variants all come through alongside ISA 5.1. The same workspace can hold both upstream and downstream drawing sets.
