ANALISIS PENGARUH KEKUATAN ARUS TERHADAP KELANCARAN PROSES UNMOORING PADA KAPAL S.S ENERGY FRONTIER

Abstract

Tuharea, Sania Zeinrina. 2025. “Analysis of the Influence of Current Strength on the Smoothness of the Unmooring Process on the S.S Energy Frontier Ship” This study aims to analyze the influence of ocean current strength on the smoothness of the unmooring process on the LNG Carrier S.S. ENERGY FRONTIER. The problems raised focus on operational obstacles during unmooring due to strong ocean current conditions, such as the middle stern line incident caught on the ship's propeller at Hibiki Port, Japan. The population in this study was the entire crew of the S.S. ENERGY FRONTIER ship, totaling 30 people, who were also used as samples using the total sampling technique (census). The approach used is quantitative correlational, with data collection methods in the form of field observations during sea practice and distributing questionnaires. The research instrument has been tested for validity and reliability using the help of SPSS Statistics 26 software. The data analysis technique was carried out using the Pearson Product Moment correlation test, t-test, and coefficient of determination test. The results of the study indicate that the strength of the ocean current has a significant influence on the smoothness of the unmooring process, with a correlation value of 0.743 and significance (sig) <0.05. This proves that the stronger the ocean current, the more likely the unmooring process is to experience technical disruptions or operational time. The conclusion of this study is that there is a strong and significant relationship between the strength of the current and the smoothness of the ship's unmooring, so special attention is needed to monitor the current conditions before and during unmooring. The author suggests that port operators and captains improve coordination, update SOPs based on local environmental conditions, and use tools such as tugboats and real-time current monitoring systems to minimize operational risks.
