Investigating the reliability and criticality of the maintenance characteristics of a diving support vessel

Abstract

Maintenance tasks and their application in the shipping industry have evolved significantly in the recent years. Particularly in the offshore industry, safety onboard, environmental protection and intensive operational activities necessitate the minimization of down-time and the preservation of an excellent performance ratio. The first step of an innovative ship maintenance strategy, which is proposed by the authors and is based on criticality and reliability assessment, is presented herein using the FTA tool with time-dependant dynamic gates so as to represent in an accurate and comprehensive way the interrelation of the components of a system. The paper also presents a review of the maintenance standards and procedures, such as the ALARP concept, the Key Programme 3-Asset Integrity (KP3) initiative, the OREDA handbook as well as the RCM and RBI principles. As part of the reliability assessment, the Birnbaum and Criticality reliability importance measures are utilized to validate the results of the analysis. A case study of a diving support vessel (DSV) illustrates the application of this strategy. The main systems examined are: the vessel's power plant, propulsion, water system, lifting, hauling and anchoring, diving and finally the safety system. The reliability of the main systems and subsystems as well as of their critical components is identified and suggestions of how to improve the overall reliability of the various systems both at a component, system and managerial level are also proposed

Dynamic risk and reliability assessment for ship machinery decision making

“…The outcome of this study indicates that preventive maintenance is still the preferred maintenance approach by ship operators, closely followed by predictive maintenance; hence, avoiding the ship corrective maintenance framework and increasing overall ship reliability and availability. An innovative ship maintenance strategy is presented by Turan et al (2011) based on criticality and reliability assessment while utilizing the FTA tool with time-dependent dynamic gates so as to represent in an accurate and comprehensive way the interrelation of the components of a system. As part of the reliability assessment, the Birnbaum and Criticality reliability importance measures are utilized to validate the results of the analysis, whereas a case study of a diving support vessel (DSV) illustrates the application of this strategy.…”

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

“…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

“…Their methodology was demonstrated on a diesel generator system of a cruise ship. A similar methodology is also considered by Turan et al [49] and illustrated on the main systems of a diving support vessel. Recently, Zaal and Kuijt [50] have presented a methodology that streamlines the RCM approach by assessing only the functional critical failure modes.…”
