The Controllable Pitch Propeller (CPP) system is a crucial ship propulsion technology in supporting precision maneuvers, especially in narrow harbors without the assistance of tugboats. This study examines the failure of the CPP system on MT ships. Transko Aquila during the movement at Pertamina Reo's TBBM port, NTT, focusing on identifying technical, operational, and managerial factors that affect system reliability. The purpose of the study was to evaluate the impact of failures on operational efficiency and shipping safety, as well as to formulate data-driven recommendations for system improvement. The methods used are a qualitative descriptive approach with direct observation techniques, crew interviews, documentation studies, and Failure Mode and Effects Analysis (FMEA) analysis. Analysis was carried out on ten critical components of the CPP system, with assessments based on severity, frequency of occurrence, and detection ability. The results showed that the failure mode with the highest RPN value occurred in the pitch control mechanism (RPN = 216), hydraulic pump (RPN = 200), and oil cooling system (RPN = 128). Faults identified include undesirable pitch reversal, decreased hydraulic pressure, delayed control system response, and decreased RPM of the main engine. The impact includes a ±3-hour delay in docking, increased risk of collisions, and activation of emergency safety protocols. The FMEA approach has proven effective in providing comprehensive risk maps, supporting technical decision-making, and improving the reliability of the ship's propulsion system overall.

The study on the use of the Smith Bracket in towing operations highlights its critical role in securing towing connections, requiring strong structural integrity as mandated by IMO safety regulations. Using Finite Element Method (FEM) analysis, the stress distribution under various tensile loads was examined, and the simulation results indicate that the bracket design can safely withstand operational forces, making it suitable for towing applications.From the calculations: The Minimum Break Load (MBL) of the Smith Bracket is determined to be ±69 tons, Applying a Safety Factor (SF) of 4, The Safe Working Load (SWL) is calculated at 17.5 tons. These values indicate that the bracket meets safety requirements and is capable of withstanding operational loads without failure. The combination of IMO regulations, FEM simulations, and theoretical analysis ensures that the Smith Bracket is designed for safe and reliable towing operations.

This study aims to develop an effective seafarer competency improvement model in reducing turnover rates in the Indonesian maritime industry. The research method used is a mixed-method with a quantitative and qualitative descriptive approach. Data collection was carried out through questionnaires, interviews, and documentation studies of 150 seafarers from five national shipping companies. The Technology Readiness Level (TRL) of the proposed model was evaluated at TRL 7, indicating that this model has been tested in a limited operational environment with adequate results. The results showed that 65% of seafarers felt they did not receive adequate competency-based training, while 48% of them indicated a desire to change jobs shortly. The competency improvement model, designed based on digital technology and simulation-based training, succeeded in increasing the average competency score of seafarers from 68% to 85% within six months. In addition, the turnover rate of the company that became the pilot project for this model decreased from 22% to 14%. This study offers a state-of-the-art in the form of an integration of competency-based approaches with digital technology, different from previous studies that focused on conventional interventions. The novelty of this study lies in the use of a digital-based model that combines continuous evaluation and adaptive training programs that are tailored to the needs of individual seafarers. This model is expected to be a strategic solution to increase seafarer retention in the maritime industry while strengthening the competitiveness of the Indonesian workforce in the international market.

This study investigates the impact of Hull Vane System installation on fuel efficiency and speed enhancement for High Speed Craft (HSC) ferries, focusing on MV. Batam Fast 20 operating on the Batam–Singapore route. The Hull Vane, a fixed hydrofoil mounted at the stern below the waterline, is designed to reduce hydrodynamic resistance and improve vessel performance. Numerical simulations using Computational Fluid Dynamics (CFD) with RANSE-based solvers were conducted across various speeds (10–25 knots) and foil attack angles (0°, 2°, 4°,6°). Results indicate that Hull Vane offers significant drag reduction only at low speeds (10 knots), achieving up to 26.99% resistance reduction. However, at operational speeds (20–25 knots), the system increases resistance due to excessive lift, causing bow trim and higher wetted surface area. Validation was performed through grid independence studies and comparison with experimental data and Maxsurf Resistance software. The findings conclude that Hull Vane System is unsuitable for MV. Batam Fast 20 due to its hull geometry and waterjet configuration. The study recommends exploring alternative technologies such as bow foils or automated trim control systems for high-speed vessels, emphasizing the need for adaptive hydrodynamic solutions in modern ferry operations.

Gearbox is a vital component in the ship propulsion system that functions to transmit power from the main engine to the propeller. On the MV. Mas Initiative, found a discrepancy between the gearbox rotation ratio with the RPM of the main engine, which has an impact on increasing the lubrication temperature of the gearbox lubricating oil to exceed the optimal limit. This condition can reduce lubrication efficiency, accelerate component wear, andreduce overall ship performance. This study aims to analyze the factors that cause gearbox ratio mismatch, evaluate its impact on lubricant temperature, and develop technical recommendations to overcome these problems. The method used is descriptive qualitative approach through direct observation, interviews with the crew, and literature studies. The results showed that the main causes of this discrepancy include damage to gearbox components, a non-optimal lubrication system, as well as a lack of regular maintenance. The high temperature of the lubricant has an impact on decreasing the viscosity of the oil and decreasing the efficiency of power transmission. Recommended solutions include regular cleaning of the oil cooler and filter, checking the pressure of the oil pump, as well as regular oil quality testing. It is expectedthat the results of this study canbe a referencein gearbox maintenance to improve the reliability and operational efficiency of the ship.

The seawater piping system on KM. Pratiwi Indah plays an important role in supporting ship operations; however, it is highly susceptible to damage due to the corrosive marine environment. This study aims to identify the causes of the seawater piping system replacement, compare the costs between galvanized pipe SCH 40 and black pipe SCH 80, and analyze the corrosion resistance of both pipe types. The research methods include the calculation of corrosion rate, remaining life, and Life Cycle Cost (LCC), supported by data presentation in tables and graphs. The analysis results indicate that the galvanized pipe has a corrosion rate of 0.35 mm/year with a remaining life of 15.14 years, while the black pipe has a corrosion rate of 0.53 mm/year with a remaining life of 16.41 years. Although the black pipe shows a slightly longer remaining life, the LCC calculation over a 30-year analysis period demonstrates that the galvanized pipe results in a lower total life cycle cost. Based on the technical and economic analysis, the galvanized SCH 40 pipe is recommended as the more optimal material for the seawater piping system on KM. Pratiwi Indah.
