Vertically Integrated Shrimp Hatchery in Southeast Asia.

Challenge

The sponsor operated 12 nursery-and-growout farms served by a 400 million post-larvae/year hatchery that had become a hard capacity ceiling. Two disease events over the previous 18 months had also exposed weaknesses in biosecurity segmentation. The board approved a hatchery expansion to 1.2 billion post-larvae/year with fully segregated biosecurity zones and independent water treatment per module.

Strategy

The strategy chose multi-contract deliberately: the sponsor's owner's engineer had strong aquaculture-specific experience and the project's biosecurity architecture made single-wrap EPC uneconomic (every specialist contractor would have priced their unfamiliar scope with a large contingency). A three-country supplier corridor was designed for RAS technology, hatchery equipment and controls.

• Multi-contract with an experienced owner's engineer
• 3-country corridor for RAS, hatchery equipment and controls
• Biosecurity zoning frozen in FEED — no changes accepted post-freeze
• Genetics program contracted separately from equipment

The corridor-based supplier logic follows the Global Sourcing Strategy guide.

Supplier selection

Nine RAS integrators were evaluated across the three corridor countries. Six were shortlisted after documentary review; four passed reference-site visits. All shortlisted suppliers were required to demonstrate operating installations at ≥60% of the planned modular capacity. Global B2B Group remained supplier-neutral. The final selection was made by a scoring committee that included the CFO and the owner's engineer.

• Reference sites visited by veterinary and process teams jointly
• Beneficial ownership and sanctions screening on every shortlisted supplier
• Warranty and spares terms weighted equal to price in the scoring matrix
• Second-source qualification retained on genetics and probiotics

Financing

A regional development bank led the senior tranche as anchor lender; a local commercial bank co-lent on the second-lien tranche; the sponsor contributed 35% equity. The DFI applied its standard ESG performance standards (including biosecurity, effluent treatment and labour audit), which the sponsor treated as design inputs from day one rather than compliance-hurdles later.

The DFI's engagement gate replicates what the Project Financing Readiness guide describes. See the Development Banks & DFIs pillar for context.

Execution

The project was executed as three overlapping modular waves so the first two modules could begin production while modules 3–6 finished construction. FAT was conducted on RAS skids in Europe and Asia; SAT on-site was supervised by the owner's veterinary team. Interface risk between civil, RAS and controls was managed through weekly interface meetings with mandatory attendance. Two interface conflicts (drain-slope and controls I/O mapping) surfaced at week 34 and were resolved without a change-order.

• Modular waves allowed early revenue on completed modules
• Weekly interface meetings across civil, RAS, controls
• Two interface conflicts caught and closed inside PMO — no change-order
• Genetics import windows aligned to module handover dates

The staged acceptance approach maps to the Post-Award Execution playbook.

Lessons learned

• Treating ESG performance standards as design inputs (not late compliance items) removed roughly 4 months of DFI review cycles.
• Multi-contract worked because the owner's engineer had domain experience — the same structure would have failed with a generalist PMO.
• Freezing biosecurity zoning early saved an estimated USD 1.8M in rework at the module 4–6 boundary.
• Second-source qualification on genetics later proved decisive when a bio-event disrupted the primary supplier for 5 months.
• Interface meetings were where most value was preserved — not the contract clauses themselves.

Executive takeaways

• Match delivery model to owner PMO depth, not to accountant preference.
• Bring ESG requirements into the design brief on day one when DFI capital is targeted.
• Modular staged commissioning can transform payback where technology and biosecurity allow.
• Second-source qualification on inputs matters as much as second-source on equipment.
