Abstract
Reliability-Centered Maintenance (RCM) has emerged as a critical strategy in the maritime industry, aiming to optimize maintenance practices while enhancing safety, operational efficiency, and environmental compliance. This study examines the pivotal role of RCM in minimizing equipment failures, reducing accident risks, and ensuring adherence to international maritime safety, management and environmental regulations. By focusing on the functions of critical ship systems and analyzing potential failure modes, RCM enables targeted maintenance that prevents breakdowns and extends asset life. The paper highlights how RCM supports compliance with standards such as the International Safety Management (ISM) Code and MARPOL, contributing to the reduction of oil spills, emissions, and mechanical failures that could harm marine ecosystems. Through case studies and industry data, this research demonstrates that adopting RCM not only improves vessel reliability and crew safety but also plays a vital role in fostering sustainable maritime operations in an increasingly regulated global environment.
