Abstract

Energy efficiency in modern marine machinery systems is a strategic issue because fuel consumption, main-engine reliability, auxiliary machinery performance, and emission compliance determine ship operating costs and environmental sustainability. This research analyzes challenges and solutions for improving the energy efficiency of machinery systems on modern vessels. The method used is a narrative literature. The review shows that machinery energy efficiency is affected by fuel quality, fuel oil purification, main-engine combustion performance, fresh water generator reliability, shipboard electrical load forecasting, hybrid energy management, battery-electric readiness, ammonia engine design, and onboard carbon capture. The main challenges include fluctuating sea conditions, degradation of mechanical components, fuel contamination, limited space for energy storage, safety risks of alternative fuels, and the competence of engine-room personnel in data-based operation. The most realistic solutions are condition-based maintenance, fuel quality monitoring, optimized purifier operation, waste heat utilization, power demand forecasting, energy management systems, and a gradual transition toward hybrid, battery, ammonia, and carbon-capture technologies. This research concludes that energy efficiency must be treated as an integrated technical, operational, managerial, and educational concern.
