MODES: TRANSIT CRUISING Cruising speed in conventional diesel mechanic mode Reduced fuel and maintenance cost with smaller main engines
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
MODES: DP HIGH DP High with main engines and shaft alternators Reduced fuel and maintenance cost with smaller main engines
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
MODES: TOWING Diesel mechanic mode Using only main engines
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
