ANALISIS PENYEBAB OVERHEATING TERHADAP KEBOCORAN SISTEM HIDROLIK HATCHCOVER DI MV. GREEN HELSINKI

Abstract

Reggina Silwa Wira Yudha, 2025. Analysis of the Causes of Overheating Against Hydraulic System Leaks Hatchcover at Mv. Green Helsinki. Overheating and leakage in the hydraulic system are two major issues affecting the performance of the hatch cover during cargo operations on MV. Green Helsinki. This study aims to analyze the causes of overheating and leakage in the hydraulic system and evaluate the maintenance efforts conducted onboard. A qualitative method was used, employing direct observation, interviews with crew members, and documentation during sea practice from August 2023 to August 2024. The research findings indicate that overheating frequently occurs due to inadequate oil cooling systems and continuous hatch cover operations without sufficient cooling intervals. Meanwhile, leakage is mainly caused by worn seals, loose pipe fittings, and a lack of routine inspection of hydraulic components. These issues lead to cargo operation delays, increased risk of workplace accidents, and higher vessel operating costs. This study recommends improving the hydraulic oil cooling system, implementing a structured preventive maintenance schedule, and enhancing crew training in early detection of hydraulic system failures. With proper system maintenance and adequate crew understanding, hatch cover performance is expected to improve, ensuring more efficient and safer ship operations.
