GRAID completes its endurance test

Huge achievement for the team

For GRAID’s final test, the robot ran its own kind of marathon. In a feat of endurance, it was placed inside the pressurised rig – again at 77 bar (g) and 5m/s flow – but this time for 12 hours. The purpose of this was to prove that it could run for long periods, not just short spells, without its condition deteriorating. Again, it passed with no recorded issues.

When the robot is operating at its maximum operating pressure it will see pressure five times greater than what a submarine will deal with. When you consider how harsh the environment was – and the fact it had to withstand those conditions for longer than a typical working day – that’s a huge accomplishment.
