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.

P&ID extraction for Chevron CES projects.

Chevron projects run against the CES family. Tagsight extracts I/O lists, instrument indexes, equipment lists, and line lists 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.

Run it on your Chevron projects.

Upload the relevant P&IDs and export the Chevron-shaped instrument index and I/O list.
