ELFA Hybrid marine propulsion system
Slide 2
Market & Suitable Applications
ELFA technology is suitable for virtually all boat application whether commercial, recreational or government.
Propulsion systems up to 1.5 MW Above 1.5 MW an industrial solution may qualify, unless space restraints make it impossible
Displacement Hull application up to 130 feet Recreational, Commercial and Government
Planing Hull applications Small hulls up to 35-40 feet diesel electric, above 40 feet hybrid propulsion
Fast speed patrol applications Vessel with extreme load profile either loiter or fast speed with multiple hotel load requirements
Auxiliary marine systemsWing shafts, thruster, fire pumps etc

Traditional Propulsion Problems
Slow AccelerationQuick acceleration results in clouds of black smoke, the maritime equivalent of burning rubber in a high-powered car
Precision Maneuvering is DifficultRelatively high idle speed of the engine complicates low-speed maneuvering
InefficiencyStandard fixed-pitch propellers match the power capability of the engine only at one point
Cramped Engine RoomCongestion in the engine room can make inspection and maintenance difficult
Inflexible Boat DesignSpace required for propulsions takes away from living space
Limited Engine Torque At Lower RPMs
Slide 5
Diesel-Electric Alternative
Design flexibility
More efficient operation of engines reduces fuel consumption and/or extends range
Precise control while docking and maneuvering
Less noise, vibration, heat, and emissions
Plenty of electric power throughout your boat
Alternative layouts with batteries, fuel cells, solar panels

Diesel-Electric Solution
Design and arrangement flexibility for naval architects
Installation flexibility for boatyards
Save space and increases payload
Boats designed for this type of propulsion will benefit the most from the layout

CAN*-Bus Structure
Modular concept, whereby configuration of the application is programmed in the DICO
Available software supports all kind of hybrid applications (diesel-genset, fuel cell, pure battery, trolley, dieselelectric)
Motors / generators could be either torque or speed controlled
Inverter software is standard solution, supporting all different applications and used in more than 20 different projectsDuo-DC/AC-inverter Duo-DC/AC-inverter
