The generator is mounted to a variable speed Cummins QSL9 410 mhp diesel engine. The system offers parallel hybrid powering of the AC traction motor from either the generator, the batteries, or both. The motor is coupled to the propulsion shaft via a reduction gear for thrust and increased propeller ef- ficiency. AMM said that with this configuration, torque is immediately available for the propeller, and the speed can be precisely controlled. BAE Systems’ HybriGen system has lower engine operating hours is more streamlined than a conven- tional drive, requiring fewer parts, thus resulting in savings in both fuel consumption and maintenance costs. Adding Enhydra to Red and White Fleet exhibits the company’s environ- mental commitment while providing an acceptable return on investment. The hybrid system also uses battery power from two 80 kWh lith- ium-ion battery packs. Inherent in the Enhydra’s design is the ability to expand the size of the batteries to reach complete zero-emissions operation in the future as charging infrastruc- ture advances and battery technol- ogy improves. This current battery system can meet any power demands of the Enhydra. Simultaneously, the propulsion system provides a silent, emissions-free experience for recre- ational cruise excursions. The BAE HybridDrive system can automati- cally use full electric battery operation at slower speeds and when maneuver- ing in and out of the harbor with the Enhydra’s two four-blade propellers. At higher speeds, the generator will automatically engage and augment the additional power demands of the traction motor. Enhydra’s innovations make Red and White Fleet’s Vice President of Operations Joe Burgard hopeful for future possibilities. “We are very pleased with the team All American Marine has put together to deliver this unique vessel and are eager for our guests to experience San Francisco Bay from the silent decks of Enhydra,” Burgard said. “We see the propulsion configuration on the Enhyrda as phase one in our move toward the full elec- trification of our fleet.” Red and White Fleet is also heavily involved in the creation of Water- Go-Round, the nation’s first ferry to be powered by hydrogen fuel cells, which is planned to be ready for testing in 2019.  n
