Conversions of smaller vessels to 750V DC hybrid systems

Many ferries, tugs, workboats, yachts and other vessels of less than roughly 500 tons are ideal candidates for conversion to hybrid-electric propulsion. This presentation will examine the cost and performance tradeoffs that affect the economic viability of undertaking a refit to hybrid power. Driveline, electrical system and battery options will be compared, and design examples of conversions employing 750V DC electrical systems will be explored in detail. Considerations for incorporating onboard photovoltaic arrays will also be presented.
