The demand and cost of marine gas oil is predicted to double over the period to 2030.
With a focus on craft to 50m such as the fishing fleet, coastal, harbour ferries and workboats, DCM Power will with its technology partners, leading Equipment Manufacturers, specify design and supply fully optimised Hybrid Propulsion solutions which enable owners to prepare for the significant challenges which lie ahead.
The retrofitting of Hybrid Propulsion systems to an existing boat requires the matching of components to the specific demands of that vessel.
In series hybrid propulsion, the diesel engine is not connected to the propeller but drives a generator which supplies power for an electric motor which drives the propeller. While similar to the well-established Diesel Electric propulsion system there are however fundamental differences such as an energy storage and power management system which determines in real time the optimum source of power for the motor.
As a rule, it can be said that Series Hybrid System is ideally suitable for vessels which typically operate on inshore or inland waterways such as cross harbour ferries or harbour tugs while parallel Hybrid systems are better suited to sea going trawlers. Energy Storage can be incorporated with either system further improving the overall efficiency through peak shaving of electrical loads and the ability to steam and manoeuvre on stored power produced at peak efficiency.
What kind of Efficiency Improvements are possible with Hybrid Propulsion?
The potential reduction in fuel consumption is dependent upon the vessel, the configuration selected, the extent of energy storage and the vessels operating profile.
For repowering of existing trawlers, a fuel reduction of between 12 to 18% is achievable while in the case of new builds where the hull can also be optimised efficiencies in excess of 20% are obtainable.
For ferries or work boats on a series configuration, reductions in excess of 20% can be achieved.
