Abstract

The hatch cover is a critical structural component of a general cargo vessel, designed to safeguard cargo from seawater ingress and maintain watertight integrity. This study evaluates the constraints affecting the execution of planned hatch cover maintenance aboard MV. Orient King. A qualitative single-case study design was employed over a 12-month onboard observation period. Data was collected through semi-structured interviews with three key deck personnel (Chief Officer, Bosun, and Able Seaman), structured operational observations, and a review of maintenance logs. Thematic analysis of the data revealed that maintenance compliance is fundamentally hindered by aggressive marine corrosion, a brittle supply chain causing 2-to-3-month lead times for critical spare parts (e.g., rubber packing, hydraulic hoses), and a dense operational tempo that routinely forces the deferral of scheduled Planned Maintenance System (PMS) tasks. Consequently, temporary repairs are frequently substituted for permanent solutions, elevating the risk of cargo damage. To mitigate these risks, this paper proposes a prioritized action plan, emphasizing strict adherence to the company's Safety Management System (Document No. JSP E41), optimized spare-part inventory control, and enhanced supervisory protocols.

Abstract

A conveyor is a tool with a large rubber band arranged transversely between two pulleys at a constant speed as a transporter of solid material in this case coal with the provisions of the permitted amount. Damage to the conveyor tool has a major impact on the smooth running of a coal loading and unloading process, so a coal monitoring tool was designed using an ESP32 microcontroller-based data logger. The purpose of this study is to find out how to design a coal load monitoring tool based on a data logger using the Research and Development (R&D) method type ADDIE. Using the following types of testing: static and dynamic. The research results show that the load monitoring system based on a load cell and ESP32 microcontroller demonstrates high accuracy, with a reading deviation of less than 2% from the actual weight. The system is also considered effective, as it can detect loads, adjust the hatch door angle, and transmit data to Google Spreadsheet in real-time without disruptions. Its ability to adapt to varying loads indicates that the prototype operates stably, responsively, and in accordance with the design objectives.
