Amongst the demands of Hydro Tunnel inspection, often Penstocks are deeper than the 300m capability of the Standard Seaeye Falcon. To meet this requirement Vocean have upgraded the Falcon to 400m operational rating. This required extensive audit of all external pressure housings. Where necessary housings were replaced. The system has recently been proven, being dived to 376m on four successive dives. A further increase to 600m operational capability is in the final planning stages and will be implemented if the market indicates demand.
