Sunday 20 September 2009 a problem during the deployment phase led to its demonstration wave generator overturning as it was being taken out to sea to begin its year-long offshore trial.
Hit by a severe storm January 8th 2004 the main mooring connection broke and the platform drifted towards the shore where it stranded close to the beach.
Mc Cabe Wave Pump, Destroyed during sea trials during unexpected storm early 2000.
