Özet

Operational, measurement, and software-related failure types directly affecting energy efficiency and sustainability performance in commercial ship management were comprehensively investigated within the framework of the FMEA (Failure Mode and Effects Analysis) methodology, blending the practical field experiences of 32 experienced maritime authorities (chief engineers, technical superintendents, and inspectors). This research aims to systematically reveal the sources of risks in the face of increasingly stringent environmental regulations in the maritime sector. The findings clearly demonstrated that carbon intensity and sustainability gaps on vessels stem not only from mechanical failures, but largely from data quality deficiencies, manual operational habits, and calibration deviations.

RPN scores across all failure modes were reduced by an average of 80% to 90%, thereby elevating operational reliability to the highest level. Viewed from a cost-benefit analysis perspective, interventions with zero or very low cost such as direct digital data transfer from VDR and automation systems or draft automation instantly eliminate human-induced transcription errors, offering an extraordinary cost-benefit ratio.

As a conclusion and comparative summary, the most logical starting step for companies is to focus on low-cost software and automation moves that quickly bring down the RPN. These steps should be followed by strategic investments which have high costs but yield massive fuel economy and legal compliance returns. Software-based subscriptions, on the other hand, should be implemented gradually according to the company's budget flexibility, protecting CII ratings while optimizing EU ETS costs. Accordingly, achieving maritime enterprises' sustainability targets relies on digitizing manual processes, adopting real-time sensor verification protocols, and holistically supporting operational discipline with FMEA-based risk management tools.
