For matching various working condition of ship propulsion system, a modified mean value model of a large-scale low-speed directly reversible marine diesel engine is put forward. A starting and braking torque module is added to the conventional model. A new friction model which considers static friction is adopted. So, the new model can run smoothly across all propulsion working condition, such as starting, running, braking, reversing, etc. The dynamic simulation models of propeller running across four quadrants and ship longitudinal motion are given too. The 5S60MC marine diesel engine equipped on a 76000DWT bulk carrier is taken as an example. The simulation results show that steady data of diesel are in good accordance with test-bed data, and dynamic data match to ship sea trial data in crash stop condition. The best is to read these instructions and follow the outline of this text.
