Diesel Mechanical Propulsion
There are three primary configurations within the Diesel Mechanical system. A single Diesel Mechanical configuration runs the propeller through a reduction gearbox, with or without a PTO. It is a system that can be driven either with a constant or with a slightly varying engine rpm, dependent on simultaneous running of an electric generator. A twin-in single-out ‘Father & Son’ configuration is a flexible system for vessels with two or three working conditions.
The profit of this configuration is sourced from an optimum combination of the main engines, thus reducing fuel consumption to a minimum. A twin screw twin-in single-out configuration provides the largest flexibility in power. By using the two, three or four engines in this configuration, the average efficiency is good. In this arrangement, the redundancy of this system is also very beneficial.
