1 CAT HYBRID THRUSTER

2 TYPICAL AZIMUTH THRUSTER ARRANGEMENT Example: 7000hp Vessel Shaft Alternator Switch Board Main Engine Gensets Main CP Thruster Example: Engines: MaK 8M25C, Thrusters: CAT MTA 730 CP Gensets: CAT C18, 340ekW

3 HYBRID AZIMUTH THRUSTER ARRANGEMENT Example: 7000hp Vessel Booster Drive Smaller Main Engines Shaft Alternator Switch Board Booster Motor Bigger Gensets Main CP Thruster Example: Engines: MaK 6M25C, Thrusters: CAT MTA 730 CP + 600kW Booster Gensets: CAT C32, 940ekW

4 CAT MPC 800A: CONTROLS Thruster Control PMS Interfacing & Genset Control Booster Motor Speed & Load Engine Speed & Load Mechanic/Electric Load Balancing Mode Selection & Automation

5 MODES: TRANSIT CRUISING Cruising speed in conventional diesel mechanic mode Reduced fuel and maintenance cost with smaller main engines

6 MODES: TRANSIT ECONOMIC SPEED Cruising speed in conventional diesel mechanic mode Reduced fuel and maintenance cost with smaller main engines Economic transit with one/two gensets in diesel electric mode 10-15% reduced fuel consumption in 7-8kts range Optional to run one main engine as a genset Optional

7 MODES: DP HIGH DP High with main engines and shaft alternators Reduced fuel and maintenance cost with smaller main engines

8 MODES: DP LOW & STANDBY OPERATION DP High with main engines and shaft alternators Reduced fuel and maintenance cost with smaller main engines DP Low & Standby in diesel electric mode with main engines Main propulsion running in variable speed reducing power and fuel consumption Optional to run main engines as gensets Optional Optional

9 MODES: TOWING Diesel mechanic mode Using only main engines

10 MODES: TOWING AND ANCHOR HANDLING Diesel mechanic mode Up to 75% power Hybrid mode with gensets and main engines working together Up to 100% power Main propulsion running in variable speed reducing power and fuel consumption
