Abstract

The purpose of this paper is to discuss the importance of the chief officer's role in the loading and unloading process on a ship. Loading and unloading containers on a ship must be carried out as well as possible, in relation to the safety of the ship, crew and cargo. Because the stability of the ship also depends on the handling of the cargo that has been arranged, so in this case the chief officer is responsible for everything related to loading and unloading. The chief officer is the head of the deck department, is one of the management levels of the four deck department officers who are directly responsible to the captain and is the second person in charge after the captain. One of the duties of the chief officer is to carry out supervision during loading and unloading activities. In this case, the role of the chief officer is very necessary considering the main tasks he carries out and the need for knowledge to carry out these tasks. The method used by the author in compiling this research is by collecting data through observation, interviews, and literature studies. The discussion obtained data related to the importance of the chief officer's role in the loading and unloading process of containers on the ship. The results of this paper are about the importance of the chief officer's role in handling loading and unloading as a reference and provision for an officer on the ship later. The conclusion of this writing is the importance of the role of the chief officer in the loading and unloading process on the ship. And a chief officer must be able to calculate the GM stability of the ship.

Abstract

 The purpose of this paper is to discuss the occurrence of oil spills at sea, handling of oil spills to prevent pollution of the marine environment. The causes of oil spills include ship operations including loading and discharging, grounding, collision, hull leaks, damage loading and unloading equipment, explosions or fires and other causes. Oil spills with a volume of 7-700 tons when collide 26 percent and due to ships aground 19 percent when ships are loading and unloading and bunkering. Oil spills a volume of >700 tons occurred when the collided 30 percent aground 31 percent. To reduce the impact of oil spills, the implementation of the oil spill contigency plan (OSCP) carried out. Implementation of the contigency plan include teamwork, data collection, assessment, use of equipment, supervision and monitoring, cooperation related parties and evaluation. The method is by collecting data by observation, and literature study. The discussion obtained data on the causes oil spills and countermeasures with contigency emergency plans. The resul this paper is analysis of the causes of oil spills and countermeasures. The conclusion is oil spills are caused by ship operations including ship accidents. And steps to minimize the potential for wider pollution by implementing an oil spill contigency plan.

Abstract

The operations of cargo loading and unloading on chemical tankers have a high level of risk because they involve hazardous liquid cargo and complex technical systems. These conditions can cause operational disruptions if they are not supported by proper supervision, coordination, and optimal operation of the cargo system, one of which is the occurrence of overflow and overpressurized tank. This study aims to analyze the causes of overflow and overpressurized tank and their impacts on cargo loading and unloading activities on the chemical tanker MT. Marina Aman. This study used a qualitative approach with a descriptive case study method. Data were obtained through observation, interviews, and documentation studies. The results showed that the overflow occurred due to an abnormality in the Pump Remote Control Assembly of the 4S cargo tank pump, which caused the pump to operate without a command and resulted in cargo being transferred to the 2S tank without being noticed. This condition was worsened by the malfunction of the remote tank gauging system on the 2S tank and the failure to report an early indication in the form of an abnormal pump sound. Meanwhile, the overpressurized tank was caused by the less optimal performance of the Pressure/Vacuum (P/V) valve and pressure sensors, as well as delays in maintenance. These results show that the occurrence of overflow and overpressurized tank was not caused by a single factor, but was influenced by a combination of equipment conditions, monitoring systems, maintenance, and human factors. The impacts included disruption of cargo loading and unloading activities, damage to the tank structure, and operational losses for the company. Therefore, improvements in equipment maintenance, cargo system monitoring, and more effective communication and reporting are needed during cargo loading and unloading activities.
