EPC selection
Short answer
EPC delivery concentrates responsibility in one contract. That is valuable when the buyer has limited in-house engineering capacity, and expensive when the scope boundary is loose. The criteria below focus on where aquaculture EPC contracts actually fail: interfaces, assumptions and undefined scope.
The most damaging EPC disputes come from what sat between two scopes: site preparation, drainage, intake and outfall works, power connection, water rights, buildings, and the process equipment interfaces. Require a written battery-limit list that states exactly where the contractor's responsibility starts and stops.
“Provide a battery-limit list with every interface named and allocated.”
General industrial EPC capability does not transfer automatically to a live biological facility, where water quality, biosecurity and commissioning sequencing determine whether the plant works. Look for delivered aquaculture facilities, not adjacent process plants.
“Which aquaculture facilities have you delivered, at what capacity, and with which process partner?”
Clarify whether the EPC owns the process technology, licenses it, or integrates a third-party supplier. That relationship determines who is accountable when biological or water-quality targets are missed, and whether you can select the technology independently.
“Do you supply, license or integrate the process technology, and who warrants it?”
Most EPC scope is delivered by subcontractors. Ask which packages are subcontracted, whether local firms are used, how they are supervised and what happens to warranty if a subcontractor exits after handover.
“List subcontracted packages, supervision arrangements and warranty pass-through.”
Request a milestone schedule with critical-path items, long-lead equipment identified, and the contractual consequence of delay. In aquaculture, schedule slip has a biological and market cost, not only a financial one.
“Provide a milestone schedule, long-lead list and delay remedies.”
Define what handover means: mechanical completion, water-tight and running, or a stabilised biological system holding target water quality. These three points can be months apart and cost very different amounts.
“Define mechanical completion, performance acceptance and biological handover criteria.”
Aquaculture EPC guarantees typically cover equipment, workmanship and system parameters under stated inputs — not fish performance. Understand the conditions attached to each guarantee and the evidence required to invoke it.
“State each guarantee, the conditions attached and how compliance will be measured.”
Evaluate training, operating manuals, maintenance programmes, remote support and the cost of a post-handover service agreement. The facility must be operable by your own team.
“Describe training, documentation and post-handover service options with pricing.”
Categories, not rankings. Companies are named as examples of who operates in each category; inclusion is not an endorsement and the list is not exhaustive.
Technology-led EPC
Integrators that extend from system supply into full project delivery. Scope depth varies by bidder and region, so compare exactly what each turnkey offer includes.
Construction-led EPC
Regional construction or industrial contractors delivering the facility with a process technology partner supplying the aquaculture system.
Owner's engineer model
The buyer keeps the contracting structure but appoints an independent engineering firm to specify, supervise and verify — often used when multiple suppliers are procured directly.

FishMatch can be a fit when a buyer needs structured RFQ intake, aquaculture-specific calculators, project-specific technical information and a clearer procurement path for aquaculture supplier selection, RFQ preparation and supplier-neutral proposal comparison. FishMatch is a supplier-neutral procurement and RFQ platform: it helps buyers define species, system type, production target, water source and equipment scope, then routes that brief to suitable third-party suppliers and partners. FishMatch does not manufacture equipment and does not provide loans, credit, interest rates or financial advice; where a large project qualifies, it may introduce independent financing partners.
