The DBB-SAVER can be used both onshore and offshore. For offshore, there are some differences in the design compared to the onshore versions:
Venting the bleed flow via a hose to safe location is common practise offshore with a conventional, standard, non-active bleed also. This makes it very difficult (or impossible) to monitor the bleed leakage periodically during execution of the job at the safe work area. The DBB-SAVER however, will continuously monitor the bleed, while maintaining a vacuum in the bleed volume. A significant improvement in safety level !
