STRUCTURAL RELIABILITY OF MARINE DIESEL ENGINE PROPULSION SHAFTING SYSTEMS
A method for estimating the reliability of the propulsion shafting system of a diesel ship is presented, involving: probabilistic modeling of the diesel engine and the propeller torsional excitations; determination of the statistical properties of the torsional vibratory stress amplitude at any point on the shaft; analysis of first excursion and fatigue failure modes; and estimation of each shafting segment failure probability. Examples using existing propulsion shafting systems are presented. It is shown that the requirement of a high value for the traditional safety factor does not always ensure that the system is safe.
