Hybrid power for research vessel

Following a complete vessel restoration, Transfluid’s HM3350 hybrid module is powering the Western Flyer, a boat with a storied history and legendary past, and now a showcase for the future of marine propulsion. Mounted between the 425hp diesel engine and marine gear, the HM3350 provides up to 200hp of full electric propulsion. The parallel installation enables the motors to charge the batteries when the boat is using the engine propulsion. This flexible design allows the Flyer to carry out its new mission as a research vessel completely silently when on station, using the HM3350 to maneuver and power the onboard hydraulic systems via clutchable PTOs installed on the drive.

Transfluid has provided the propulsion control, CANbus communication system, batteries and all the components of the complete hybrid supply. The operator can switch from diesel to electric mode with the press of a button and engage or disengage the hydraulics from the control bridge.

Requiring just 68.5cm of driveline space, the HM3350 is ideal for this retrofit, maintaining the classic look and feel of this legendary boat while ushering in a new wave of technology. For energy storage, 115kWh of lithium iron phosphate batteries provide over three hours of autonomy at a speed of 8kts and power the house load. Transfluid has hundreds of similar installations worldwide, pioneering a sustainable future.
