As part of Deliverable D6.2, led by National Technical University of Athens (NTUA) an important series of tests is currently underway, focusing on the validation of insulation systems, tightness performance, and the Hydrogen Detection and Monitoring Safety System (HDMSS). These activities represent a critical step toward ensuring the safe handling, storage, and long-term operation of liquefied gas systems.
The first two testing phases concentrate on insulation integrity and system tightness. Their primary objective is to verify the safe handling and distribution of liquefied gas across key components, including:
- Piping networks
- Pumps
- Valves
- Storage tanks
Beyond structural integrity, these tests also investigate several parameters that directly influence boil-off behavior — a crucial factor for long-term system efficiency and safety. Among the parameters being assessed are:
- Heat leakage, which impacts thermal performance and boil-off rates
- Ortho-para hydrogen conversion, affecting thermodynamic stability
- Sloshing phenomena, which may occur during vessel motion
- Flashing effects, linked to pressure and temperature variations
Understanding and mitigating these factors is essential to optimize equipment durability, operational reliability, and overall system safety over extended use.
The third testing phase focuses on confirming the proper functionality of the HDMSS. This advanced monitoring system plays a vital role in safeguarding operations by providing continuous real-time oversight of critical parameters.
The system includes:
- Temperature sensors to monitor thermal conditions
- Gas detectors to identify potential leaks
- Pressure sensors to supervise vacuum levels within insulation layers
- Data analysis software for continuous evaluation
- Integrated warning and alarm modules to trigger alerts in the event of leakage or malfunction
By validating the performance of these components, the project ensures that potential risks can be detected early and addressed promptly, reinforcing operational safety.
The work under D6.2 is currently being distributed among the involved partners, reflecting the collaborative nature of the project. Each partner contributes its expertise to specific testing activities, ensuring a comprehensive and technically robust validation process.
This coordinated effort marks another significant milestone toward achieving safe, efficient, and reliable liquefied gas systems — supporting the broader objectives of innovation, sustainability, and technological excellence within the project.
