Planning Scenario: Planning Phase 2 of an Existing Aquaculture Project
This is an illustrative planning scenario, not a case study, a delivered project record or an engineering design. Figures are planning-level indications to structure a capacity review.
Short answer
How do you plan this growth step? — Phase 2 of an existing project
Phase 2 has an advantage no greenfield project has: real operating data. Use Phase 1's actual biomass curve, oxygen consumption, energy use, feed conversion and downtime to set the Phase 2 design basis, then decide deliberately whether to repeat the Phase 1 supplier package or re-tender it — continuity reduces spares and training cost, re-tendering tests price and technology.
- Key asset:
- Phase 1 operating data as the design basis
- Key decision:
- Repeat the Phase 1 package or re-tender
- Common trap:
- Shared utilities sized only for Phase 1
- Investment class:
- Multi-million USD
Current operation
Phase 1 operating, with one or more cycles of real production data available.
Growth target
Phase 2 capacity added on the same site, using validated assumptions from Phase 1.
Systems requiring engineering and supplier capacity review
These are areas to investigate before committing to the target tonnage — not confirmed deficiencies on any specific farm.
- Shared utilities
Intake, electrical and effluent systems designed for Phase 1 usually need a step change, which can dominate Phase 2 cost.
- Site services
Roads, feed storage, workshop and staff facilities were often sized for Phase 1 only.
- Permits
Discharge and abstraction consents may be capped at Phase 1 volumes and need re-application lead time.
- Supplier continuity
Mixed vendors across phases multiply spare parts, training and control-system integration work.
- Control system integration
Phase 2 should appear on the same monitoring and control platform as Phase 1, not a parallel one.
- Post-harvest capacity
Harvest, chilling and processing were sized for Phase 1 tonnage.
Equipment categories
- Production units matched to the validated Phase 1 design basis
- Utility upgrades: intake, pumping, electrical distribution, effluent
- Aeration/oxygenation sized on measured Phase 1 oxygen consumption
- Extension of the existing monitoring and control platform
- Feed storage and distribution for combined tonnage
- Post-harvest and cold-chain extension
Utilities to verify
- Grid and backup capacity for combined Phase 1 + Phase 2 load
- Water abstraction and discharge consents at combined volume
- Site logistics for combined feed and harvest movements
CAPEX drivers
- Extent of shared-utility step change required
- Whether Phase 2 repeats or upgrades the Phase 1 technology
- Permitting and environmental scope
- Automation retrofit on Phase 1 during Phase 2 works
- Post-harvest capacity extension
Implementation phases
- 1Phase 0 — Data review
Convert Phase 1 actuals into the Phase 2 design basis: biomass curve, oxygen, energy, FCR, downtime.
- 2Phase 1 — Utilities & permits
Resolve the shared-infrastructure step change and consents before ordering production equipment.
- 3Phase 2 — Procurement
Decide continuity vs re-tender and run a normalized RFQ on that basis.
- 4Phase 3 — Build & integrate
Construct and integrate on the existing control platform with minimum disruption to Phase 1.
Tools for this scenario
What the RFQ must contain
- Design basis: species, target annual tonnage, cycles per year, harvest size and peak standing biomass.
- Site data: water source and quality, temperature range, salinity, available area, grid capacity.
- Scope split: what the supplier delivers, what is local scope (civil, electrical, installation).
- Performance basis each supplier assumes, stated explicitly rather than implied.
- Energy: installed load per system and expected running hours, so operating cost is comparable.
- Commissioning, training, spare parts and service response terms.
- Delivery terms (Incoterms), lead time and payment schedule.
