BAE’s hybrid power system for Vermont research vessel

BAE Systems announced it has been selected by Chartwell Marine to supply the electric hybrid power and propulsion system for a new maritime research vessel for the University of Vermont. As part of the contract, BAE Systems will supply and integrate the hybrid system, working with the vessel’s builder, Derecktor Shipyard in Mamaroneck, N.Y.
“Using green energy to power transportation in the water is an essential part of establishing cleaner waterways and harbors in places where we live, work, and visit,” said Steve Trichka, vice president and general manager of Power & Propulsion Solutions at BAE Systems. “This proven and reliable technology will create a new and sustainable way for the University of Vermont to conduct its critical research.”
BAE Systems’ HybriGen power and propulsion system is designed to help reduce both carbon emissions and the use of fuel by the vessel, which will serve as a floating classroom and lab for students of the Rubenstein School of Environment and Natural Resources conducting research on Lake Champlain.
The system consists of a compact, bearingless variable speed generator coupled directly to the engine crankshaft that can generate power at any engine speed. The generator delivers power for auxiliary power needs such as heat, air conditioning, lighting, and working deck gear, as well as charging the Energy Storage System (ESS). Propulsion is through BAE’s HDS200-ACTM (ac traction motor) rated 200 kW.
BAE Systems said the technology builds on its 20-plus years of experience developing and integrating power and propulsion systems. Those systems power more than 13,000 transit buses around the globe, BAE said, and have passed certification and inspection by the U.S. Coast Guard.
