Ship Universe Cruise Tool
Cruise Ship Laundry Water, Steam & Energy Cost Tool
Estimate cruise laundry throughput, fresh-water demand, wastewater, hot-water heating load, steam consumption, electricity, boiler-fuel equivalent and annual utility cost. Advanced mode models separate laundry categories such as guest linen, towels, uniforms and galley linen.
Currency selector changes display only. No exchange-rate conversion is performed.
Water Demand
Gross wash water, recycled-water credit, fresh-water makeup and wastewater
Steam & Energy
Hot-water heating, direct process steam, washer power and finishing power
Operating Cost
Water, wastewater, electricity, steam or boiler fuel and cost per kg processed
Laundry Throughput & Water Use
Enter dry laundry mass before rewash. Rewash increases processed laundry and utility use. Water reuse reduces modeled fresh-water makeup.

Laundry Utility & Cost Results
Blended laundry utility analysis
Enter laundry data
Enter laundry throughput, water, steam and electricity assumptions
to estimate cruise laundry utility demand and annual cost.
Planning estimate only.
Actual cruise laundry utility use depends on washer type, loading,
program selection, linen mix, soil level, rinse count, tunnel-washer
configuration, water reuse, extraction performance, dryer moisture
removal, ironer and finisher configuration, steam pressure, condensate
return, heat recovery, equipment condition and operating practice.
Recycled water may also retain useful heat, so a simple water-reuse
percentage does not fully represent heat recovery. The model treats
direct process steam as separate from wash-water heating and may
double-count energy if entered machine data already includes both.
Average hourly utility demand is not a peak-load calculation. Use
measured machine and ship-utility data for design, retrofit or capacity
decisions.
