Designed by Pantocarene Naval Architects this hull form is fast and efficient lending itself to a Hybrid option, whilst maintaining the characteristics of the ORC 136. The parallel hybrid system is supplied by Transfluid and is coupled with a 400 HP Yanmar engine. There is the option to run under electric power supplied by a lithium-ion battery bank coupled up to 4 x 75kw electric motors (two per shaft) or simply under conventional diesel power. For additional speed both the electric motors and the diesel engine can be run in unison giving a boost in speed. The synergy of engine RPM aligned with its power are matched correctly with the RPM of the electric motors thus providing three propulsion options, which also has the benefit of increased redundancy. This current specification is for the Port of London Authority duty cycle, but other options are available.
In specifying a hybrid solution for your requirements the predicted duty cycle is critical. We take into account the speed and range required under electric power, the speed and range under diesel power and finally the top speed when operating in in both electric and diesel power combined. Recharging the Lithium-ion battery bank is done either via the on-board diesel engines or via a 3 phase charging system supplied from ashore.
