During this phase, the concept for the RAS facility is developed and the project is broadly defined. A preliminary study is conducted to assess feasibility by identifying and analyzing parameters such as production requirements, building footprint, and cost efficiency.

A preliminary feasibility study typically includes:
– RAS dimensioning / Water quality requirements
– Temperature variance
– Salinity levels
– Oxygen & lime consumption
– Biomass capacity & density
– Biofilter & degassing capacity
– Fish feeding rates
– Water flow per tank/system & retention time
– Water exchange and intake capacity (fresh / marine water)
– Initial energy consumption report
– Building footprint & layout drawings (LOD 100)
– Cost & risk analysis
– Design time schedule
– Scope of Works (SOW)
