Abstract
Working regime (WR) of the main propulsion plant (MPP) with marine diesel engine (MDE) is the established parameter set of: MDE’s power; rotary speed of propeller (or engine); ship’s speed (Pw-n-V), [kW—rpm—knot], so that the MPP’s major components are not subjected to mechanical and thermal overload. The WOR is established in accordance with the followings: Real operation conditions of hull and propeller; uniform working cycles of the MDE’s cylinders; fuel consumption characteristics of the MDE. The selecting WOR was carried out on the base of: digital databases constructed during the design and construction phase of the ship MPP; result of predicting misfire states of cylinders and an established optimal functional. The instantaneous power signal is calculated by product signals of the instantaneous torque and average rotary speed. The WOR forecasts were verified for the MPP of the MV.HR34000DWT using the simulation software programmed on LabView, at the normal working sea-conditions.
