The model simulates a vertically integrated krill fishery and processing plant, from harvesting under CCAMLR catch limits through on‑board or shore‑side conversion of whole krill into high‑value meal and oil. It captures the seasonal window (typically 4–6 months) and the impact of voyage timing on catch composition.
A dynamic mass balance engine tracks raw krill through cooking, pressing, decanting, and drying stages, with yield curves that respond to the lipid content of incoming batches. The split between meal and oil volumes automatically adjusts as lipid levels fluctuate, enabling realistic revenue forecasting for a market where oil commands a significant premium.
Operational logic pairs vessel days‑at‑sea, fuel burn (linked to engine load and distance), crew expenses, and maintenance schedules with the processing rate. The model incorporates by‑catch handling, hold capacity constraints, and transshipment logistics, so that bottlenecks in the chain are visible.
On the revenue side, pricing mechanisms distinguish standard fishmeal, krill meal for aquafeed, and pharmaceutical‑grade krill oil, with the option to apply contract and spot price mixes. Regulatory royalty fees (CCAMLR access fees) and certification costs (MSC) are built into the fixed‑cost structure.
Capital expenditures cover vessel acquisition/retrofit, processing equipment, cold storage, and auxiliary infrastructure. The model phases investments across a pre‑catch period and includes commissioning delays. The user can test what‑if scenarios on vessel capacity, processing throughput, and product yield to evaluate project returns under different quota allocations and lipid profiles.
