Abstract

Safety of life at sea is a paramount operational priority that heavily relies on crew preparedness in managing maritime emergencies. This study evaluates the effectiveness of abandon ship drills in improving crew readiness on the commercial tanker MT. Pagerungan. Using a qualitative case-study design, data were collected over a 12-month period through direct participant observations, structured interviews with six key personnel, and documentary analysis. Effectiveness was measured using specific operational indicators: alarm response time, correct usage of life-saving appliances (LSAs), compliance with muster list duties, and communication efficiency. The results indicate a significant gap between administrative compliance and practical readiness. Drills were conducted only four times annually, violating the monthly requirement stipulated by the Safety of Life at Sea (SOLAS) Convention. Observations revealed critical deficiencies, including the inability of junior and catering crew members to correctly don lifejackets and a lack of role awareness among specific deck ratings. Furthermore, commercial pressures and a tendency to view drills as bureaucratic formalities hindered the development of a robust safety culture. The study concludes that while incremental improvements were observed across repeated drills, overall effectiveness remains structurally fragile. Recommendations include the rigorous implementation of monthly drills, integration of pre-drill toolbox meetings, station-specific compliance checklists, and documented competency assessments to bridge the gap between regulatory mandates and actual emergency preparedness

Abstract

This research was conducted to analyze the implementation of deck crane maintenance, identify operational obstacles, and formulate optimization efforts to improve the cargo handling performance on MV Tanto Keluarga. The study utilized a qualitative descriptive approach supported by quantitative operational data, gathering evidence through 12 months of observation during sea practice, ship documentation analysis, and semi-structured interviews. The informants included the Chief Officer, Bosun, and an Able Seaman. The findings reveal that deck crane maintenance was significantly delayed due to the high pressure of the ship's port schedule, which disrupted the Planned Maintenance System (PMS). Consequently, the lack of timely lubrication led to critical wire rope wear and slewing gear corrosion. This chain of component degradation directly caused a heave-up system disruption, resulting in a documented 4-hour operational downtime during cargo discharging in Tobelo Port. Optimization interventions were systematically carried out through strict pre-operational visual inspections, massive re-lubrication, and schedule calibration between cargo operations and preventive maintenance. Following these interventions, subsequent loading and unloading operations recorded zero technical downtime, demonstrating a tangible improvement in equipment reliability and operational efficiency
