Abstract:The objective of this study was to determine the technical and economic feasibility of repowering a diesel-fueled
New York State Canal Corporation (NYSCC) work boat with a diesel hybrid-electric or full-electric powertrain.
The project team instrumented a NYSCC dredge tender to capture in-use data to determine the vessel’s duty cycle.
A comprehensive evaluation of commercially-available hybrid-electric and full-electric marine powertrains was
performed. The results revealed that only one full-electric system met NYSCC’s performance and cost targets. A
cost-effective electric powertrain system is expected to handle approximately 95% of the dredge tender’s typical
duties. The remaining high energy use cases that are not met will be handled by NYSCC dispatching a diesel boat.
An evaluation of the available electric recharging infrastructure on shore and using excess power from mobile work
platform generators was also performed. The investigation revealed that shore power was available at many, but
not all, locations where the boat frequently visits. The project concluded that hybrid-electric and full-electric
powertrains are a potentially viable technology option for NYSCC to consider to reduce its operating costs, carbon
footprint, and energy use. Thus, NYSCC and New West Technologies proposed a Phase II field demonstration
project to NYSERDA and NYSDOT to install a full-electric powertrain and perform a long-term field
demonstration project to validate the electrically-powered boat’s performance. The Phase II project was awarded
and is expected to be completed in early 2014.
