Paul KunjaliMarakkar School of Marine Engineering Cochin University of Science and Technology Cochin India ABSTRACT Shipping Companies are looking for an optimised Maintenance Model to be incorporated into the Safety Management System of the Ships operated by them. Coming into terms with what the best maintenance practise for each of the shipboard machinery is the need of the hour. Optimisation of Maintenance actions will enhance the safety and reliability of the machinery. It is believed that both over maintenance and under maintenance are to be avoided to enhance the efficiency of the concerned machinery. This paper attempts to develop a numerical maintenance model to determine the optimal inspection regime to be followed for shipboard machinery. The maintenance modelling is carried out by Delay Time Analysis using a down time estimation model. The model is validated using operational data original equipment manufacturer recommendations and historical failure data collected from Wartsila A6L20C auxpac system.
