This paper perpetuates a long established practice of periodically presenting the findings derived from the failure investigations undertaken by Lloyd's Register (LR). The principal aim is to share some of the technical experience gained from these activities. Case studies with a strong practical bias are described in a way that is intended to interest marine engineers. The interpretation of the results and the opinions expressed are, however, necessarily those of the authors rather than of LR. A comparison with previous papers shows that failures continue to occur due to material fracture mechanisms, which are generally well understood. Examples have been selected to illustrate the wide diversity of causes associated with design, manufacture, operation, maintenance and repair that can damage shafts. Particular emphasis is focused on fatigue crack growth characteristics and the potential detrimental implications of fretting, corrosion, surface flaws and the incidence of thermal cracks due to rubbing contact. The case studies also demonstrate the interdependence between engineering measurements, metallurgical examinations and calculations in conducting failure investigations.
