Energy Infrastructure Project Lifecycle: From Feasibility to FEED, EPC/EPCM and Commissioning

Executive takeaway

Which reference points frame the decision?

Why start with demand rather than equipment?

A terminal, depot, onsite storage system or energy asset exists to deliver a measurable service: volume, availability, throughput, quality, flexibility or resilience. Before selecting a concept, define who will use the asset, at what rate, with what peaks, products, interfaces and duration. An asset sized on an unstressed central demand case can become oversized, undersized or badly located.

The demand case should separate committed needs, assumptions and options. Stress lower volume, schedule delay, energy substitution and regulatory change. The decision to fund a study is not the investment decision; it buys reduction in uncertainty. This prevents teams from defending a technical solution simply because engineering effort has already been spent.

What should feasibility demonstrate?

Feasibility compares options on one basis: demand, location, logistics, land access, utilities, HSE, permits, constructability, fit-for-stage CAPEX/OPEX, schedule, interfaces and economics. It should identify fatal flaws and the information required before the next gate. A highly precise CAPEX number can create false maturity when definition is still weak.

The output is not only a preferred case. It should explain why alternatives were rejected, which risks can still change the decision and what studies remain. Every material assumption needs an owner and validation date. If permits, ground conditions, grid connection or port access remain uncertain, the business case should show that dependency.

What are concept, pre-FEED and FEED supposed to achieve?

Concept work turns the requirement into an architecture: capacities, flows, major equipment, interfaces, operating philosophy and design criteria. Pre-FEED deepens unknowns that govern cost, safety and schedule. FEED then seeks enough definition to support procurement, permitting and the selected construction strategy.

Exact phase boundaries vary across organizations and projects; FEED is not a universal certification. The gate should use agreed deliverables: design basis, balances, layouts, HSE studies, equipment lists, interfaces, execution plan, estimate and schedule with clearly stated precision. Decisions should test evidence sufficiency, not the phase label.

How should EPC, EPCM and other contracting strategies be chosen?

EPC can concentrate more responsibility with a contractor, while EPCM generally leaves more interfaces, contracts and decisions with the owner. Neither model is inherently superior. Choice depends on scope maturity, owner capability, risk appetite, contractor market, flexibility, schedule and interface-management capacity.

Risk allocation creates value only when the party carrying the risk can manage it and the price of transfer is understood. Transferring poorly defined risk often returns as contingencies, exclusions or change orders. Before tendering, map responsibility for design, procurement, construction, permits, interfaces, testing, performance and handover.

Why must permitting and HSE be integrated into design?

Administrative approvals are not a final task to bolt onto the schedule. In Morocco, different petroleum-depot and commissioning activities can follow distinct procedures. Build a permit register with authority, dossier, dependencies, lead time and owner. Competent legal or regulatory specialists should confirm the pathway for the actual site.

The same applies to HSE: containment, drainage, fire systems, separation, access, hazardous areas, inspection and spill response shape layout, materials, utilities and cost. IFC guidance provides an international benchmark but does not replace Moroccan law or owner standards. CAPEX savings achieved by deleting a required control are degradation, not optimization.

How should cost, schedule and contingency be controlled without false precision?

Tie every estimate to definition level, basis, date, exclusions and contingency. A single number without range or assumptions creates unjustified confidence. Track physical drivers as well: quantities, lengths, volumes, power, productivity, unit rates and market conditions. Variances then become explainable.

The schedule should show critical path, long-lead items, interfaces and owner decisions. Stress permit delay, equipment delay, adverse ground conditions and slower ramp-up. Project economics should capture impacts on revenue, interest during construction, site costs and commercial commitments without double counting the same consequence.

What does commissioning readiness actually mean?

Commissioning starts long before first product or first energy. Prepare systems, procedures, spares, competence, inspections, as-built records, tests, punch lists, emergency plans, maintenance and acceptance criteria. Mechanical completion does not automatically mean operational readiness.

Handover should connect technical evidence with organizational capability. Define who accepts each system, what residual items may remain open and which conditions block operation. Performance tests should use agreed criteria and traceable data. Every material deviation becomes a decision: correct it, approve a controlled concession or delay start-up.

What should an investment committee receive?

Present the decision requested, demand case, alternatives, technical maturity, permit map, HSE risks, CAPEX/OPEX with estimate basis, schedule, contracting strategy, funding, sensitivities and gate conditions. Separate proven facts, assumptions and open decisions.

The committee should be able to say yes, no, or yes subject to conditions. Every condition needs an owner, evidence and date. The purpose is not to make the package reassuring; it is to expose the variables that can still destroy value or block operation.

Checklist — 10 project-gate questions

Are the requirement and time horizon approved?

Were alternatives compared on one basis?

Were fatal flaws explicitly tested?

Are land, utilities and interfaces qualified?

Is the permit register complete and owned?

Are material HSE risks integrated into design?

Do CAPEX/OPEX state basis, date, accuracy and exclusions?

Does EPC/EPCM strategy match owner capability?

Does the schedule expose critical path and long-lead items?

Are commissioning and handover criteria defined?

Frequently asked questions

Does FEED mean cost is guaranteed?

No. FEED improves definition, but final cost still depends on market conditions, contracting, changes, site conditions and execution. The estimate must continue to state its basis, exclusions and level of accuracy.

Is EPC always lower risk for the owner?

No. Some risks can be contractually transferred, but they are usually priced and interface, change or poor-definition risks can remain. The model should match scope maturity and the owner’s management capability.

Can procurement start before FEED is complete?

Selected long-lead items may justify early commitment, but exposure rises if design changes. The decision should identify frozen interfaces, assumptions, rework consequences and commitment authority.

Is a siting approval enough?

Not necessarily. Applicable procedures depend on facility and stage. The Ministry directory distinguishes several processes; the actual pathway should be confirmed with competent authorities and advisers.

When is a project bankable?

Bankability does not follow from engineering maturity alone. It combines demand/revenue, risk, contracts, cost, permits, sponsors, funding and debt-service capacity. Article 05 treats this framework for terminals.

Does ANFAXIS perform regulated engineering sign-off?

No regulated sign-off claim is made here. The website may describe coordination, feasibility and execution support only within approved evidence; activities requiring licensed specialists must be delivered by competent parties.
