Introduction When an existing equipment or a structure has reached or exceeded its finite design lifetime presumed by the manufacturer, its ow er has l gitimately t ask himself crucial questions, such as: - Can I continue to use it as it is now and without danger? FATIGUE DESIGN 2021, 9 th Edition of the International Conference on Fatigue Design "Residual Life of Structures and Equipment" B. Depale 1 , M. Bennebach 1* 1 CETIM, 52 avenue Felix Louat, 60304 Senlis, France Abstract This paper deals with the problem of evaluating residual life of structures and equipment often in service for years and that may have reached or exceeded the end of their design life. In spite that the problem is encountered in many industrial sectors and represents a major concern, references available for dealing with it are often limited. Selected European and ISO references potentially suitable for this purpose for steel structures and cranes are presented and discussed in this paper together with some of the practical problems faced by the engineers responsible for evaluating the residual life of equipment and structures. A general methodology is presented for the assessment and management of residual life of existing equipment and structures that has been developed by CETIM (Technical Institute for Mechanical Industry), with an example of its application to loading bridges of Calais harbour. The paper also deals with the potential links with the EN 45550 series of standards dedicated to the assessment of energy-related products concerning their durability and ability to be repaired and reused.
