Introduction: This study investigates the real-world effects of pollutants on ship heat exchangers in the marine sector, focusing on the complex issues influencing maintenance expenses, environmental sustainability, and operational effectiveness. The core of the issue is figuring out a long-term, practical way to lessen the damage that heat-exchangers surface heat-exchangers surface fouling causes to ship heat exchangers. Purpose. The article aims to investigate and evaluate how pollutants affect ship heat exchangers in the marine sector from a practical standpoint. It seeks to shed light on how pollutants, such as chemicals, debris, and oil residues, impact a vessel’s environmental sustainability, maintenance costs, and operational effectiveness. The essay analyzes the complex issues caused by surface fouling-induced damage, highlighting the dangers of decreased thermal conductivity, greater overheating, higher maintenance costs, longer downtime, and possible environmental effects. Result. One practical consequence of pollutant-induced damage is that it calls for substantial and frequent cleaning, repairs, and maybe replacements of the heat exchanger components, which raises maintenance costs. Traditional cleaning procedures involve prolonged downtime for manual intervention, which worsens the economic effects on shipping businesses and trade routes. Furthermore, the study highlights the negative effects uncontrolled pollutants have on the environment, highlighting how crucial regulatory compliance is to avoiding legal ramifications and preserving the good name of the sector. Conclusion. In conclusion, preserving marine operational effectiveness and environmental sustainability requires reducing the impact of pollutants on ship heat exchangers. The selection of particular heat exchanger types requires customized cleaning techniques. Advanced solutions are provided by ecologically safe chemical agents, high-pressure water jets, and automated robotic systems. To avoid losing efficiency, regular cleaning must be done under the direction of real-time monitoring. Maintaining heat exchanger performance and guaranteeing the lifespan of ship power plants in the face of changing surface fouling concerns requires striking a compromise between operational needs, environmental responsibility, and proactive maintenance.
