Oil & Gas · Operational Assurance

Move from mechanical completion to safe, stable, compliant operations.

CitiriOS helps owner-operators govern readiness for startup, SIMOPS, cold runs, process safety, SOPs, training, spare parts, asset data, operational acceptance, and production ramp-up.

The readiness gap

Mechanical completion does not mean a unit can start up safely.

Process safety must be assured, PSSR and RFSU distinct and complete, operators competent, cold runs passed, spare parts staged, and asset data handed over — before startup and the ramp to nameplate operations.

Readiness domains

Everything a startup has to coordinate.

One Readiness Room spans every workstream that must be true before a startup go/no-go — each with owners, criteria, and accepted evidence.

Operations assurance

Owner operational readiness across the asset.

Process safety

Process-safety assurance and barriers.

PSSR / RFSU distinction

PSSR vs RFSU kept distinct and complete.

OTS / cold-run trials

Operator training simulator and cold-run trials.

Operator competency

Operator competency assured and recorded.

Emergency response

Emergency response readiness and drills.

Spare parts & data handover

Critical spares and asset-data handover.

SIMOPS & stabilization

SIMOPS controls and ramp to nameplate.

Gate & evidence model

Three kinds of gate. One startup decision.

A startup decision depends on distinct authorities. CitiriOS keeps startup gates, process-safety evidence, and operations acceptance separate and traceable.

Owner soft gate

RFSU / startup readiness

Startup readiness gates owned by the operations readiness team, accepted against criteria.

Regulatory hard gate

Process safety / regulatory

PSSR, statement of fitness, HSE and regulatory evidence — cannot be overridden by the owner.

Operational acceptance

Operations acceptance

Owner acceptance to start up and ramp toward nameplate, with residual conditions.

CitiriOS workflow

The same platform — in operational assurance language.

Every CitiriOS module maps to how owner-operators run a startup.

Readiness Room

Every workstream, stakeholder, trial, issue, dependency, and gate for a startup.

Ready Score

Startup readiness index by domain, with what is dragging it down.

Evidence Packs

Audit-ready PSSR, RFSU, and process-safety evidence for HSE and regulators.

Gate Authority

Startup, process-safety, and operations-acceptance gates kept distinct.

Dependency Graph

SIMOPS, cold-run sequences, and spare-parts dependencies made explicit.

Handover & Acceptance

Asset-data acceptance, conditions, and stabilization to nameplate operations.

Example scenarios

Target outcomes Illustrative · not a customer claim

When a startup is governed as evidence rather than status, owner-operators aim to start up safely on schedule, close cold-run issues faster, and ramp toward nameplate with a defensible record.
