Abstract
A ships propulsion transmission system with at least one engageable friction clutch (10, 18) in the drive line between the ship engine (28, 30) and propeller (26), characterized by a device (20, 70, 6, 14, 76, 108) for setting the operating pressure of the friction clutch (10, 18) during the starting up process time-dependent and sequentially so that the operating pressure during the starting up process, is at least once, at a peak level and then subsequently is at a lower intermediate level, before it then is held at the final level.
