Increasing ship operational reliability through the implementation of a holistic maintenance management strategy

Abstract

Ship maintenance was initially considered as more of a financial burden than as a way to preserve safety, environment and quality transportation. The benefits from applying a sound and systematic maintenance policy are emerging both in the minimisation of unnecessary downtime as well as in the increase of operational capability. In this paper, a novel predictive maintenance strategy is demonstrated, combining the existing ship operational and maintenance tasks with the advances stemming from new applied techniques. The initial step for the application of the above-mentioned strategy is also shown regarding the machinery space of a cruise ship. Well-known tools are applied such as Failure Modes, Effects and Criticality Analysis (FMECA) and Fault Tree Analysis (FTA). Outcomes of this study are the identification of the critical components of the system, the estimation of the reliability of the overall system and sub-systems, the prioritisation of the maintenance tasks and finally the availability of the specific end events/items

Risk-Based Maintenance Scheduling with application to naval vessels and ships

“…The concept of RBM Scheduling is very similar to the Reliability and Criticality -Based Maintenance (RCBM) framework developed for ship applications by Lazakis et al (2010). RCBM uses an assigned 'criticality' akin to a risk index to schedule maintenance.…”

“…Related RCM studies exist with ship applications (Lazakis (2011);Lazakis et al, 2010;Turan et al, 2011;Wabakken, 2015) although they cannot be considered RBM Scheduling as they do not strictly schedule maintenance based on risk. Therefore, consistent terminology and critical analysis of the eight existing RBM studies is required to develop an RBM Scheduling framework for application to ship maintenance.…”

“…The Fuzzy Analytic Network Process (FANP) decision making methodology has been applied to the issue of shipyard location selection in Turkey (Guneri et al, 2009). Further examples exist apply the RCM framework for ships and naval vessels; such as the work of Lazakis and colleagues (Lazakis (2011);Lazakis et al, 2010;Turan et al, 2011) who adopted a Multi-Criteria Decision Making (MCDM) approach for ship maintenance scheduling. Recently, Emovon and colleagues have applied MCDM methods in order to select maintenance approaches (Emovon, 2016b;Emovon et al, 2015), conduct Failure Modes and Effects Analysis (Emovon, 2016a), and determine inspection intervals for marine machinery (Emovon et al, 2016).…”

“…1. This transition approach has been derived from the RCM framework for ships developed by Lazakis and colleagues (Lazakis (2011);Lazakis et al, 2010;Turan et al, 2011). This approach covers the minimum requirements for RBM Scheduling as a maintenance framework listed previously.…”

A survey of maintenance and service logistics management: Classification and research agenda from a maritime sector perspective

“…Conachey [47] discusses the technical background of this study and provides additional information related to maintenance and risk analysis of maritime systems. Lazakis et al [48] propose a criticality and reliability assessment methodology by using operational data and expert judgments. Their methodology was demonstrated on a diesel generator system of a cruise ship.…”
