After the NAA demo, we took a tour of the Hydro and were able to try out the use of the Limpet as a means of easily accessing and fall protecting work to clean and maintain the inside of the translucent, air filled, ETFE walls that are the most distinctive feature of the venue. After rolling the Limpet out of the arena on its jacked up anchor frame, we parked it below the leaning outer wall and rigged the line up and got to work. 30 minutes later everyone was covered in dust, but we'd been successful in proving its usefulness for that application.
