Process utilities design report
Use @utilities-design-report to prepare a utilities report from an existing
process report, model and design basis. The agent coordinates existing utility
modelling and reporting capabilities. It adds the consumer, case, supply,
distribution and safety-interface evidence needed to judge utility capacity.
This is an agent workflow, not a new command-line report generator. It reuses the process-study report for model extraction, tables, balances and BFD/PFD sheets, and the existing task report for the utility narrative, registers and specialist appendices. A passed process-report check does not validate utility generation, distribution or availability.
Start the agent
Select the agent and give it the process-model or task-folder path, existing process-report revision, facility type, project phase, utilities in scope and the engineering decision. For example:
@utilities-design-report Develop a concept utilities design report for this offshore gas-processing model based on its process report. Cover heating, cooling, steam/condensate, instrument air, nitrogen, fuel gas and water, with firewater, flare, drains and electrical interfaces. Compare normal, turndown, startup, summer/winter and one-generator-out cases. Provide consumer schedules, utility flow diagrams, capacity margins, standards evidence and open actions.
Missing project requirements remain visible data gaps. The agent searches the task inputs and authorized sources before requesting information. Calculated values come from reproducible models or documented calculations, not prose.
How the agents work together
| Responsibility | Existing capability |
|---|---|
| Scope, case/consumer reconciliation, report and acceptance review | @utilities-design-report and neqsim-utilities-design-report |
| Utility levels and consumer quality requirements | neqsim-utilities-specification |
| Screening supply-system sizing | @utility-design and neqsim-utility-design |
| Process and utility flowsheets, Python or Java | @process-model, @network-energy-systems |
| Heat recovery and generation/electrical interfaces | neqsim-heat-integration, neqsim-power-generation, neqsim-energy-systems-and-electrification |
| Model tables, balances, BFD/PFD evidence | @process-study-report and process-study-report |
| Firewater, relief/flare and mechanical verification | neqsim-firewater-deluge-design, @safety-depressuring, @mechanical-design |
| Standards and independent review | neqsim-standards-lookup, @standards-review, @review |
Use installed community specialists when useful; authorized enterprise overlays may add company requirements. Preserve capability identity, provenance and licensing boundaries. Public examples contain synthetic data only.
Required evidence
Keep the process report’s case and tag IDs and record its revision. Identify each utility consumer, header, return, load source, delivery conditions and applicable operating cases. Distinguish zero load from an unavailable load. Account explicitly for internal heat recovery, generation auxiliaries, losses, intermittent consumers, duty/standby status and future allowance.
Evaluate compatible simultaneous demands. The governing case for cooling may differ from that for air, nitrogen, steam or firewater. Do not add mutually exclusive consumer maxima or treat a production-maximum case as a startup or emergency case. Where topology differs, run a separately identified process model/report package rather than violating the process-report same-topology case contract.
Check the complete supply-to-consumer path, including minimum terminal pressure, temperature grade, quality, return/backpressure and usable storage. Loss-of-utility scenarios must include dependencies: electrical loss can also remove cooling, instrument air, nitrogen generation or fuel-gas conditioning. Availability requires evidence of independent supplies and auxiliaries, not only a count of installed machines.
The skill contains report content and drawing guidance and reusable input templates. Utility flow diagrams should show supply and return headers, consumer tags, battery limits, flow direction, reference case, legend, drawing number and revision. Distinguish calculated, specified, estimated and unavailable data. Render and inspect every sheet and report page. Concept P&IDs remain explicitly marked drafts until their discipline review.
Standards
Reuse the main process-report standards workflow. Add a project applicability and requirement matrix, using the skill’s standards guide. Candidate references include NORSOK P-002, ISO 10628 and ISO 14617 for process design/drawings; ISO 8573-1 and ISA-7.0.01 for air quality; adopted piping and pressure-equipment codes; API relief/flare standards; adopted firewater and electrical standards; and actual water/discharge requirements.
The guide records official catalogue evidence checked on 2026-10-25, including NORSOK P-002:2023+AC:2024 and ISO 14617-1:2025. Recheck editions and amendments before issue and retain the project-adopted edition separately. Catalogue verification is not clause verification. No fixed air pressure, nitrogen purity, receiver duration, firewater demand or spare margin is prescribed by this workflow.
Acceptance and delivery
Deliver the controlled utility report, process evidence appendix, case/consumer/ capacity registers, calculation files, standards assessment, editable diagrams, rendered sheets, validation record and open-action list in the task folder. Each utility conclusion names the governing case, criterion, source and result.
Apply the skill’s utility gates in addition to process-report validation. Unresolved failed criteria block an adequacy claim; missing requirements remain unassessed and restrict readiness. Screening boiler, nitrogen and Carnot-fraction refrigeration models do not establish vendor performance, detailed mechanical design, transient response or installation certification. A reviewer must be able to reproduce the values and see every limitation affecting the decision.
