The Life Cycle Performance AssessmentLife Cycle Performance Assessment (LCPA)(LCPA) Tool developed in the first phase of the HOLISHIPHOLIstic optimisation of SHIP design and operation for lifecycle (EU H2020 project) (HOLISHIP) project (Maggioncalda et al. 2018) was tested in the herein presented application caseApplication Case (AC) dealing with the “Design for MaintainabilityDesign for maintainability of a Research Vessel’s Engine Room”. In this relation, we further developed the methods for the estimation of the operational and maintenance costsMaintenance costs of a Research Vessel, by using a structured and flexible tool capable of evaluating the investment, operational and maintenance costsMaintenance costs for different engine room configurations and of identifying the best solution for elaboration at the design stage (design for maintainabilityDesign for maintainability). The engine room space optimisationOptimisation and accessibility were also evaluated by use of a developed 3D Three-dimensional (3D)digital mock-up, enabling the assessment of the potential impact on maintenance costsMaintenance costs in relation to the clearance space around the machinery and their compliance with specific requirements. After a general introduction to the topic provided in Sect. 5.1 of the chapter, Sect. 5.2 describes the reference vessel used in this Application CaseApplication Case (AC), with a focus on the main characteristics of the propulsion system and electric power generation. Section 5.3, besides an overview of the standard maintenance techniques, describes the implementation of the Mean Time Between Maintenance (MTBM)Mean Time Between Maintenance (MTBM) in the LCPA tool, based on the best working point of an engine. Section 5.4 identifies the alternative solutions for the propulsion layout, proposed with respect to the base configuration, while analysing the obtained LCPALife Cycle Performance Assessment (LCPA) results in terms of economic and environmental Key Performance IndicatorsKey Performance Indicators (KPIs) (KPIs). Finally, Sect. 5.5 presents the results of further investigations on ship designShip designfor maintainabilityDesign for maintainability by using the digital mockup of a 3DThree-dimensional (3D) model of the engine room and focusing on accessibility analysis.
