2025-10-02T17:58:33-07:00

PT Salam Pacific Indonesia Lines (SPIL) is a leading container shipping company in Indonesia based in Surabaya. Established since 1970, SPIL has grown into the largest technology-based container shipping company in Indonesia, serving more than 40 ports throughout the archipelago. In its operations, SPIL relies on a fleet of ships with complex engines that require periodic and specific maintenance to maintain optimal performance and the sustainability of ship operations. Ship engine maintenance often involves replacing components or spare parts, where contractor work order sheet management is a crucial aspect. This study discusses the obstacles faced by SPIL in ship engine maintenance operations, such as uncertain delivery schedules, unclear work instructions, limited delivery route options, external factors such as weather, and ineffective communication processes. To overcome these obstacles, SPIL optimizes the submission of Contractor Work Order Sheets (LOKK) by utilizing modern technology, such as supporting applications (mySpil) or integrated information systems. In addition, improving human resources through staff training and coordination, as well as better document management and periodic evaluations are also carried out to support the optimization of ship engine maintenance operations.

Perawatan Fuel Oil Purifier untuk Menjaga Kualitas Bahan Bakar Mesin Penggerak Utama di Kapal MV. LBN 15

2025-10-02T18:12:43-07:00

Fuel Oil Purifier is a device used to separate dirt and water from fuel (fuel oil) using centrifugal force. Optimal Fuel Oil Purifier performance to support the smooth operation of the ship and ensure clean fuel from water and dirt. On the MV. LBN 15 has a Fuel Oil Purifier to help the Fuel Oil purification process. The purpose of the study is to discuss the factors that cause the suboptimal performance of the Fuel Oil Purifier, and how to care for the Fuel Oil Purifier. In this case, the author uses a qualitative method, with data collection through direct observation, interviews with machine officers, and documentation, to find problems that occur and how to overcome them. The results of this study showed a decrease in performance caused by damage to the o-ring in the pilot valve, the presence of mud deposits in the disc and bowl, and the lack of implementation of the Plan Maintenance System (PMS). This problem causes the inability to carry out the blow process, resulting in overflow to the sludge tank. Maintenance efforts include cleaning and replacing components, checking inlet and outlet temperatures, and adjusting operating pressure to keep it within normal limits. The maintenance is proven to be able to restore performance to optimal condition, as demonstrated by the stability of the operating pressure and temperature and the absence of alarms or disturbances during operation.

Kinerja Governor pada Mesin Induk di atas Kapal MT. Patra Tanker 3

The governor on board is one of the components that has a very important role in regulating engine speed and maintaining the stability of the engine rotation. Optimal governor performance can support the smooth operation of the ship, preventing overspeed or slow speed when the ship is manufering. The governor can cause problems if reguler and optimal maintenance is not carried out. At the MT. Patra Tanker 3 use engine type 4 stroke diesel main engine with 775 rpm of maximum speed. The normal rotational speed of 4 stroke main engine varies depending on the application and engine size. The purpose of this study is to discuss the performance of the governor on the main engine, the impact of the governor's performance not optimal, and the causes of the governor's performance is not optimal. In this case, the author uses a qualitative method, where data collection is carried out through direct observation, interviews, documentation to find problems that occur and how to overcome them. The results obtained from this study show that the performance of the governor on the main engine at the MT. Patra Tanker 3 is very good because the governor can maintain the stability of speed even in the condition of a ship with a fairly heavy load, there is no overspeed and slow speed. This can happen due to maintenance, adjustment, and replacement of parts that are in accordance with the serial number or part number and according to the running hours.

Perawatan Sistem Pendingin Mesin Induk di Kapal KM Dharma Kartika IX

The main engine cooling system on board a ship functions to maintain optimal engine operating temperature and prevent overheating, which can damage engine components. This research was conducted aboard KM Dharma Kartika IX during a 12-month sea practice (PRALA) to identify the causes of increased freshwater temperature in the cooling system and to determine effective maintenance strategies. A qualitative method was employed through direct observation, interviews with engine officers, and analysis of maintenance documentation. The findings revealed that the primary causes of rising freshwater temperature include clogged sea chest filters due to marine debris, fouled coolers, valve operation errors (human error), and inadequate maintenance and monitoring of pump pressure and cooling temperature. In addition, incorrect valve labeling led to the closure of essential cooling water flow, resulting in engine overheating. To maintain optimal cooling system performance, several measures were implemented: the application of a Planned Maintenance System (PMS), routine monitoring of pump pressure and cooling temperature, regular cleaning of sea chest filters and freshwater coolers, and thorough documentation of all maintenance activities. Improving crew discipline and awareness also plays a key role in ensuring system reliability. With a proper maintenance system, the cooling system can operate efficiently and support the safety and performance of the ship’s main engine operations.

Perawatan Kondensor Air Tawar terhadap Kinerja Auxiliary Boiler di atas Kapal MV. Tanto Sentosa

2025-10-02T20:31:54-07:00

The freshwater condenser plays a crucial role in maintaining the performance of the auxiliary boiler on ships, particularly on MV. Tanto Sentosa. The condenser function to convert exhaust steam into condensate water, which is then reused as feedwater for the boiler. This process improves the system’s thermal efficiency and reduces freshwater consumption onboard. This study aims to examine the role of the freshwater condenser in supporting auxiliary boiler performance and to identify maintenance steps required for optimal operation. This research employs a descriptive qualitative method through direct observation, interviews with ship engineers, and documentation of maintenance activities. The findings indicate that the condenser’s optimal performance directly affects boiler pressure and temperature stability, preventing overheating and component damage. Effective routine maintenance includes cleaning condenser tubes to remove scale buildup, inspecting for leaks, performing cascade tank blowdown, controlling condensate water quality with chemical additives, and regularly monitoring system pressure and temperature.
