Conceptual Engineering
Early-stage engineering to define viable facility concepts, screen options, and set a defensible basis for FEED and EPC.
What it is
Conceptual engineering turns early ideas into structured options that can be compared on safety, operability, cost and schedule—before committing to FEED.
Typical triggers
- New development or tie-in where scope and utilities are not yet clear
- EPF/CPF concept selection and execution strategy decisions
- Debottlenecking or phased development with constraints (space, power, shutdown windows)
- Need for cost/schedule trade-offs before FEED
Scope (what we do)
- Confirm objectives, boundaries, battery limits, and key constraints
- Define basis of design assumptions and data gaps
- Develop concept options (process blocks, major equipment, utilities, interfaces)
- Identify key risks and execution constraints
- Recommend a preferred concept with decision rationale
Deliverables
- Concept selection note/report (options, pros/cons, risks, recommendation)
- High-level process block diagram / system narrative
- Major equipment + utilities list (indicative sizing ranges)
- Interfaces map (tie-ins, battery limits, packages)
- Decision register + action plan for FEED
Standards / references (high level)
API / ISO / IEC concepts where applicable, aligned to client project-gate requirements and specifications.
Engagement options
- Concept workshop (1–2 days) + follow-up package
- 2–6 week concept package with defined deliverables
- Remote technical authority for option screening
