Following nine-months of performance testing and three weeks of previous laboratory testing, the CCell device underwent final performance testing. The optimised design is suitable for sites with large tidal ranges, with the unit automatically adapting to change water levels. Survivability was design into the system from the start, with a design that inherently lows the system in heavier seas to extreme loads in the crests of waves.
Manufacturability and maintenance formed a substantial element of the design, with the team working closely with the marine contractors Leask Marine to simplify deployment and maintenance activities. The envisaged full-scale system can be maintained using a small vessel (even a canoe) and deployed rapidly.
