The installed LH2 pipes feature a double-walled design. The space between the walls is vacuumed to prevent freezing of the outer layer and to minimize thermal losses of the cryogenic gas. While this technology is well-established in land-based cryogenic systems, the uniqueness of this project lies in its implementation on a moving vessel.
The piping had to be evacuated on site. To achieve this, vacuum pumps and sensors were installed directly onboard. Limited installation space and small pump openings required an extremely flexible approach. Moreover, the ship’s power supply proved to be inconsistent. To ensure system reliability, additional safety measures were implemented, including multiple pressure relief valves.
