The project will conduct research in the domain of materials and metamaterials, focusing on the creation of innovative electromagnetic radiation metamaterials absorbers using printing technologies. PROPILEA is expected to result in the development of new commercial products that offer EM radiation protection, characterized by their lightweight design, cost-effectiveness, ease of use, and distinctive technical features, including operation in a broad frequency range. These products will serve as optimal solutions for protecting equipment and personnel in environments with significant electromagnetic radiation, such as the surfaces and various areas of ships, where high-power transmitters are in constant operation.

The objective of this project is to develop a smart, flexible, and lightweight structure that operates effectively across a wide range of telecommunication frequencies used in radar and other communication applications. Although absorbent metamaterials have been under development for over a decade, this project sets itself apart by introducing metamaterials that are not only broadband across the frequency range, but also flexible and extremely thin, enabling their adaptation into protective clothing.

The rapid advancement of sensor and automation technologies has significantly enhanced the reliability of propulsion systems in modern vessels. Diesel engines, as the primary power source, ensure high efficiency and operational stability across various conditions, while transmitting torque through long, heavy-duty shafts supported by radial bearings. Failure in any component, especially the bearings, can immobilize the vessel with severe implications for safety and cost. Over 500 such failures have been reported in recent years, each with substantial financial impact. Compounding the issue, engine subsystem faults often go undetected or misreported by crew members, further jeopardizing propulsion reliability.

To address these challenges, a comprehensive data platform is being developed to monitor, assess, and enhance the performance of marine propulsion systems in real time. This includes deploying accelerometers to model engine behavior through vibration analysis, installing high-precision strain gauges to map shaft elasticity and quantify bearing losses, and integrating advanced analytics software for evaluating component performance. The system aims to categorize operational states, predict failures, and optimize energy efficiency. A pilot installation aboard an Oceanstar Management Inc. vessel will validate the system’s functionality and real-time data accuracy.
