Abstract

Liquefied Petroleum Gas Carriers (LPG/C) play a critical role in national energy distribution systems; however, their cargo discharge operations carry significant technical risks, particularly the phenomenon of high pressure that can trigger a Cargo Temporary Stop. This study aims to identify the causative factors of high pressure during cargo discharge operations, analyze the mechanism leading to Cargo Temporary Stop, and formulate preventive measures aboard LPG/C Prima Lautan I.

Abstract

The ballasting and deballasting process is an important operational activity that plays a role in maintaining the stability and safety of the ship during the voyage. This study aims to analyze the factors that cause the ballasting and deballasting process to be not optimal and the efforts made to optimize it on MV. DK 03. The research method used is descriptive qualitative method with data collection techniques in the form of observation, interviews, and documentation related to the ballast system. The results showed that the ballasting and deballasting process was not maximized due to several factors, including ballast pipe leakage due to corrosion, damage or congestion in the ballast valve, and decreased ballast pump performance. These factors are interrelated and have a direct impact on ship stability, operational efficiency, and increase Crew workload in managing ship balance. The efforts made to overcome these problems are routine maintenance of the ballast system, installation of zinc anodes as protection against corrosion in ballast pipes and tanks, inspection and repair of ballast valves, and proper handling of ballast pump damage. By implementing these efforts in a consistent and integrated manner, it is expected that the ballasting and deballasting process can run more effectively, safely, and be able to support ship stability during shipping activities.

Abstract

This study aims to analyze the factors influencing the low level crew for awareness regarding the use of Personal Protective Equipment (PPE) and to identify the efforts made by the ship’s master to improve PPE awareness in order to prevent occupational accidents aboard LPG/C Prima Lautan I. This research employed a qualitative methode with descriptive approach. Data were collected through observation, interviews, and documentasion, while data analysis was conducted using fishbone analysis, which categorizes the causes of problems into five aspects: man, methode, machine, management, and environment.

Abstract

Varel. 2026. “Optimization of Main Deck Maintenance to Minimize Corrosion on Board MT. SHIP 111”. Diploma III Nautical Studies Program, Politeknik Pelayaran Sumatera Barat. Supervisor I: Rizal Rochmansyah, S.S.T.Pel., M.Tr.T. and Super-visor II: Melda Yanti, M.Si.This study aims to examine the implementation of the main deck maintenance, identify the factors causing corrosion, and analyze efforts to optimize main deck maintenance to minimize corrosion on board MT. SHIP 111. This study employed a descriptive method with a qualitative approach. Data were collected through observation, interviews, and documentation. The informants con-sisted of the Chief Officer, Bosun, and Able Seaman who were directly involved in main deck maintenance activities. Data analysis was conducted through data re-duction, data presentation, and conclusion drawing.The results showed that the implementation of maintenance had been carried out through routine inspections, chipping, wire brushing, painting, and maintenance recordkeeping. However, its implementation was not yet optimal due to inconsistent completion of maintenance work through the finishing stage, as well as the high workload of ship operations, unfavorable weather conditions, and inadequate equipment and materials. The main factors causing corrosion on the main deck include exposure to seawater containing chloride ions, high humidity, environmental temperature, and damage to the protective coating. Efforts to optimize maintenance include consistent im-plementation of PMS, increased supervision of maintenance activities, provision of adequate equipment and materials, and proper painting procedures through the finishing stage.

Abstract

Refined Bleached Deoderized Palm Stearin (RBDPS) merupakan muatan curah cair yang memiliki karakteristik mudah membeku apabila mengalami penurunan suhu di bawah temperatur operasional. Kondisi tersebut dapat mengakibatkan penyumbatan pada cargo line, meningkatnya waktu bongkar muat, kerugian muatan (losses), serta bertambahnya biaya operasional kapal. Penelitian ini bertujuan untuk mengetahui prosedur bongkar muat RBDPS di kapal SPOB SP4 BSI, mengidentifikasi faktor-faktor penyebab terjadinya pembekuan muatan, serta merumuskan upaya optimalisasi proses bongkar muat guna mencegah pembekuan muatan.

Abstract

The results indicate that administrative document completeness complies with the SOP, but technical execution on deck frequently deviates, such as the crew's non-compliance in using chemical-specific Personal Protective Equipment (PPE) and the omission of hose pressure test procedures. The main factors causing this non-compliance include physical crew fatigue due to tight sailing schedules, commercial pressure from the company demanding time efficiency, uncomfortable PPE design and slow bureaucracy for repairing gas detection equipment from shore management.
