“…Fuzzy AHP is a technique for ranking and prioritizing criteria in a decision-making process. The method uses the fuzzy numbers to eliminate uncertainty, inconsistencies, and subjective evaluations from decision makers’ evaluations [15] , [6] . Fuzzy AHP is widely used and accepted because it allows scholars to incorporate many different research areas, such as personnel selection, port selection, location selection, safety, security, and competitiveness evolution ( [9] ; Baştug et al, 2022; [27] ; Mollaoglu et al, 2019; [5] ; Çelik and Akyüz, 2018; [28] , [38] ; Tseng and Cullinane, 2015) Buckley proposed a Fuzzy AHP process of five main steps: pairwise comparison matrices; consistency ratio calculations for each expert; triangular fuzzy numbers; constructing fuzzy matrices; calculating fuzzy weights; defuzzification [20] .…”

“…There are various types of scrubbers, including open-loop, closed-loop, and hybrid systems, each with specific operational and environmental considerations [14]. While effective in reducing SO x emissions, scrubbers raise arguments regarding their water discharge and the associated environmental impact [15].…”

This paper presents a detailed risk assessment framework tailored for retrofitting ship structures towards eco-friendliness. Addressing a critical gap in current research, it proposes a comprehensive strategy integrating technical, environmental, economic, and regulatory considerations. The framework, grounded in the Failure Mode, Effects, and Criticality Analysis (FMECA) approach, adeptly combines quantitative and qualitative methodologies to assess the feasibility and impact of retrofitting technologies. A case study on ferry electrification, highlighting options like fully electric and hybrid propulsion systems, illustrates the application of this framework. Fully Electric Systems pose challenges such as ensuring ample battery capacity and establishing the requisite charging infrastructure, despite offering significant emission reductions. Hybrid systems present a flexible alternative, balancing electric operation with conventional fuel to reduce emissions without compromising range. This study emphasizes a holistic risk mitigation strategy, aligning advanced technological applications with environmental and economic viability within a strict regulatory context. It advocates for specific risk control measures that refine retrofitting practices, guiding the maritime industry towards a more sustainable future within an evolving technological and regulatory landscape.

“…Essential constraints for selection of compliance technology include bunker prices, ship engine type and vessel operating profile (Thalis and Psaraftis, 2018). However, some generic challenges appear to be high costs for installation, retrofitting and stability (Bas ¸han et al, 2022). Fuel tank capacity for new types of fuels is a crucial issue since it may need modifications (Lee et al, 2021).…”

“…The disposal of chemicals required is a primary concern, as shown in the use of scrubbers (Abadie et al, 2017;Claremar et al, 2017;Jiang and Hansen, 2016;Tran, 2017). Therefore, waste management has been identified as a top priority (Bas ¸han et al, 2022;Gupta et al, 2018;Mir et al, 2016).…”

PurposeThe maritime industry is the transport mode that contributes most to air pollution. The International Maritime Organization (IMO) identified the reduction of air pollution by ships as a crucial issue. Since 1 January 2020, ships have had to adopt strategies and new technologies to eliminate air pollution. However, ship compliance with nitrate oxide (NOx) emission restrictions is more challenging. This paper aims to identify ship owners' challenges in investing in new technologies.Design/methodology/approachThis paper applied a hybrid methodology combining a survey, a balanced scorecard and fuzzy analytic hierarchy process (F-AHP) to identify and evaluate constraints and weights in investment decision-making for NOx technologies. A survey was carried out to validate constraints.FindingsA survey was carried out, representing 5.1% of Greek-owned ships by deadweight capacity. The findings provide a weighted list of seven crucial technical and economic constraints faced by ship operators. The constraints vary from ship retrofit expenditure to crew training and waste management. Additionally, NOx emission technologies were compared. It was found that liquefied natural gas is the preferred investment option for the survey participants compared with selective catalytic reduction, exhaust gas recirculation and batteries.Originality/valueSeveral studies have dealt with the individual technical feasibility of NOx reduction technologies. However, apart from technical feasibility for a shipowner, the selection of a NOx technology has several managerial and safety risks. Therefore, the originality of this paper is to reveal those constraints that have a higher weight on ship owners. With this cost-benefit approach, investment challenges for ship operators are revealed. Policymakers can benefit from the results of the employed methodology.
