Ship Freshwater & RO Capacity Tool
Turn people, service loads, potable-water storage and watermaker capacity into a voyage freshwater plan. Simple mode answers daily demand, RO coverage, reserve endurance and bunker-water requirement. Advanced builds the ship from consumer groups, service loads, potable tanks, RO units and voyage legs, then checks N-1 production, feed/brine flow, product-TDS screening, energy and tank inventory across the voyage.

People / Hotel Demand Register
| Use | Group | People | L/person/day | Duty % |

Fixed Freshwater Load Register
| Use | Load | m³/day | Duty % |

Potable / Freshwater Tank Register
Usable fraction lets you keep unpumpable volume or operating restrictions outside the planning inventory.
| Use | Available? | Capacity m³ | Current fill % | Usable % |

RO Watermaker Register
Modeled product TDS = feed TDS × (1 − salt rejection). Actual product-divert logic and potable-water acceptance require the vessel’s salinity/conductivity and water-quality controls.
| Use | Available? | Rated product m³/day | Capacity factor % | Recovery % | Salt rejection % | Feed TDS mg/L | SEC kWh/m³ |
|---|
Voyage Leg Register
Legs are simulated in the entered order. Demand factor applies to baseline consumption; RO operating factor represents sea/port restrictions, maintenance or planned run time. Shore uplift is added at the start of that leg, subject to usable tank capacity.
| Use | Phase | Days | Demand factor % | RO operation % | Shore uplift m³ |
