This book is a single source of guidance and information relating to condition monitoring techniques when designing, implementing and managing a reliability-centred maintenance programme. The topics addressed in this book include a summary of the types of condition-monitoring techniques used by the marine industry, in addition to guidance on the selection of appropriate technique(s), measurement frequency, personnel skills, company resources, and risk assessment. Through the application of condition-monitoring techniques, vessel owners, onshore managers, and marine asset operators should be able to see improved equipment and system reliability onboard their vessels or other marine installations. Moreover, consideration should be given to enrolling vessels and assets in either a reliability-centred maintenance programme or a preventative maintenance programme to take advantage of the additional cost saving benefits for equipment maintenance together with receiving credit towards Class mandated continuous survey for machinery.
