System Evaluation• System operation

– Operation schedules, Control & Monitoring• Purifier operation• Filter operation

– Filtration grade, Self cleaning, Maintenance

• Cleaning system operation• Other component (valves, sensors, etc)

Space requirementsDOQ Upscale (estimate!!)(500 m3/h) (2000 m3/h)

Volume ~ 6 m3 ~ x 4Weight ~ 1000 kg ~ x 3-4Footprint ~ 5 m2 ~ x 2

• Values are without additional piping system which will be highlydependent on vessel!!

• Piping can easily be of the same size as the rest of the system!

Location• Compact• Modularity• Vibrations• Water level• Piping elbows• Free passage for crew• Service / Maintenance

Operational cost

• Power consumption ~10 kW / 500 m3/h

• Service; Cleaning fluent, Lamps

• Service cost is overall low

List of issues• Education/Information to involved resources• Space planning of piping and components• Vibrations• Integration• Materials (retrofits)• Route planning• Ships security• Automation• Electrical installation

Cost

• Main treatment components• Piping & valves• Electrical & Automation• Planning• Personel

Recommendation• Involve skilled and experienced people!
