BroadBeam/Dutch Barge Hybrid Systems

 

Our parallel hybrid systems provide the best feature/cost performance of all the competing hybrid configurations (see discussion Which Hybrid is Best?). An integrated Hybrid system has been designed to provide a complete power and propulsion solution.

The hybrid system does not disturb the normal shaft / propeller connection to the diesel, instead as the name implies it connects to the shaft in parallel with the standard diesel engine. Hybrid systems have the most to offer in efficiency improvements during low to mid power cruising and our system makes best use of this basic principle. The standard diesel engine is sized to provide the maximum power requirement for the vessel, while the electric drive is designed to match the boats mid range power needs. This allows the electric drive components to be smaller and provides a very cost effective hybrid solution. See this series of articles for a full description of system capabilities and performance.

Hybrid Marine has been suppling Hybrid packages for Broadbeams and Dutch barges since 2012 and has many satisfied customers. Take a look at our Case Studies for further information.

System overview

It takes approximately 5 to 10kW to move an average 35T Broadbeam boat at moderate canal speeds (3 to 4 MPH). The 20kW "V twin" electric motor provides this with plenty to spare for normal manoeuvring. If you are operating in adverse conditions, say crossing the channel or on a fast flowing stretch of a river, then you will need the full power of the main engine.

Typically the engine is running at just over tick over speeds (1,200 to 1,400 RPM) in restricted waters. The canal boat hybrid is designed specifically to provide up to 12 kW of power generation when cruising at this low engine speed.

In normal calm canal conditions you can drive on the electric motor for prolonged periods. How long you can go on electric drive depends on the size of your batteries. A 48V / 800Ah battery bank would last around 3 to 5 hours. Keep in mind this is continuous operation. If you are transiting a flight of locks then you are only using electrical energy when moving. This eliminates idling the engine in locks and provides considerable savings in fuel.

When the batteries run down, you start the engine and drive in the normal way. At this time the hybrid automatically becomes a generator to recharge the batteries. At typical propulsion speeds the batteries are quickly recharged via the powerful  hybrid generator and boost alternator bank. Every hour of engine drive can store enough energy in the batteries to travel between 1 and 1.5 hours in electric drive.

After the batteries are recharged you can go back to electric drive or save the energy stored for powering your electrical circuits in the evening.

System Features and functions

  • Whisper quiet electric operation yet the vessels standard diesel engine remains available to meet high end power requirements.
  • Listen to the leaves rustling in the trees and observe the wildlife as never before.
  • No more idling in locks, you can breathe fresh air and actually hear your crew from the bottom of the lock
  • Charge with the hybrid when on the move.
  • In the evening power your entire boa,t in complete silence, with the large inverter and high capacity battery bank.
  • No more engine charging in the morning/evening to top up substandard 12V batteries.
  • Cook electric in complete silence and eliminate gas onboard.
  • Significant reduction in fuel consumption and engine hours.
  • Build your hybrid canal boat for very little extra.
