Abstract:

Fatigue is a leading factor in the design of ships and particularly of high-speed vessels, where designers focus their efforts on how to define optimized structural solutions, which often imply higher design stress levels and higher flexibility. Fatigue problems may arise as a consequence of ship response to environmental loads and, locally, to the vibrations induced by the propulsion systems. The paper aims at supplying some information about the experience matured in this field by a big European shipbuilding company, also pointing out the differences between steel structures and aluminum alloy structures. The precautions in design, production, and through-life maintenance needed to prevent fatigue cracks arising after a short service period are also taken into consideration, showing that fatigue problems can be limited, if not avoided, only if every party involved is fully aware of its role and of the possible troubles induced by any deviation from the correct way to act.
