12. Five Keys to Effective Smart Cooling 12 1.Variable Speed Operation 2. Condition Monitoring 3. Operation Monitoring 4. Automated Redundancy 5. Active Valve Control

13. Active Valve CONTROL ROOM CONSUMERS POWER Seawater Pumps Freshwater Pumps Heat Exch. Variable Speed DrivesSmart Controllers Affinity Laws Q~n H~n² P~n³ Double Reward Rule Reduce Save SpeedEnergy 10% ~ 25% 20% ~ 50% 40% ~ 80% Key 1 – Variable Speed Operation 13 Reduce Pump Speed  Reduce energy consumption, reduce hydraulic loads, pumps last longer

14. Detect Pump Conditions & Wear  Prevent pump damage, reduce unexpected failures, lower maintenance cost Key 2 – Condition Monitoring 14 CONTROL ROOM CONSUMERS POWER Seawater Pumps Freshwater Pumps Heat Exch. Variable Speed DrivesSmart Controllers Smart Pump: Misalignment Coupling Damage Bearing Damage Seal Damage Dry Running Cavitation Other Unusual Active Valve

15. Key 3 – Operation Monitoring 15 Monitor & Control Operations  Protect cooling system, ultimately, protect the major unit – vessel engine CONTROL ROOM CONSUMERS POWER Seawater Pumps Freshwater Pumps Heat Exch. Variable Speed DrivesSmart Controllers Smart Controller: Warnings & Alarms On-Demand Cooling Automated Action Auto Backup Pump Datalogging Networking Sharing Inter-Controllers Control Room Active Valve
