Traditional Sea Water Cooling System 6

Traditional System: Design 7 Warm Seawater Temperature + Full Engine Speed/Load + All Time for Continuous Operation

Reality 8 Lower Seawater Temperature + Most of Operation Time Lower Engine Speed/Load +

₡ Results 9 Higher Carbon Footprint Needless Waste of Money CO 2

Intelligent Sea Water Cooling – Five Keys to Savings 10

Control: 3-Way Valve SW Pump: Max. Speed Max. Cooling All Time Result: Wasted Energy Scope of Supply (3x50%) 11 Smart System CONTROL ROOM CONSUMERS POWER Seawater Pumps Freshwater Pumps Heat Exch. Variable Speed DrivesSmart Controllers 3-Way Valve Active Valve Control: Smart Controller SW Pump: Variable Speed On-Demand When Needed Result: Savings

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

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

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

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

Key 4 – Automated Back-Up 16 Backup Pump Auto Operation  Smart back-up pump operations are fully automated, on various conditions CONTROL ROOM CONSUMERS POWER Seawater Pumps Freshwater Pumps Heat Exch.
