<![CDATA[Ship repair operations play a crucial role in maintaining operational seaworthiness, maritime safety, and the sustainability of marine transport services. An efficient repair process is key to minimising downtime, optimising resource utilisation, and reducing operational costs. This study analyses the repair process efficiency of KNP 485, a State Patrol Vessel operated by KSOP Tanjung Pakis, utilising the Failure Modes and Effects Analysis (FMEA) method. The research examines KNP 485 during its repairs at Tri Ratna Diesel Indonesia Shipyard Ltd in Lamongan, East Java. It employs the FMEA method to identify potential failures at each repair stage, assessing severity, occurrence probability, and detection capability to determine the Risk Priority Number (RPN). Data were gathered through field observations, interviews, documentation reviews, and stakeholder questionnaires. The results reveal several potential failures yielding the highest RPN values: delays in material procurement, ineffective work coordination, and delayed inspections. These factors significantly affect repair completion times and overall operational efficiency. To address these issues, the study recommends enhancing the material planning system, optimising inter-departmental coordination, implementing more structured inspection schedules, and strengthening supervision throughout the repair process. Implementing these recommendations will improve the efficiency of the repair process for KNP 485 and serve as a benchmark for maintaining other state vessels.]]>
