Hybrid Propulsion

The hybrid propulsion systems benefit of the best from two

systems - the combination of electric propulsion and diesel drive.

A Hybrid system enables ships with variable power requirements

to run at high propeller efficiency. A large number of operational

modes are available in the complex configurations, enabling

the engines and propellers to run optimally over a wide power

range. A hybrid PTH/Boost mode is a configuration where the

main propulsion is run by the diesel engine, and the system is

designed for an electric propulsion for emergency mode or as

a boost mode. In this configuration the installed electric power

should meet the minimum requirement to bring the ship to shore.

Other configurations can be optimised for electric propulsion as

one of the main working conditions. In such a system design the

vessel can utilize the power required for the specific operation in

pure electric mode, or in diesel mechanical mode, or in a boost

mode by engaging both systems. A hybrid system configuration

is a fuel efficient and flexible system, with high redundancy.
