Hydraulic powered hydrolift – Capable of operating at any depth (2015)
The Antikythera shipwreck excavation is not an easy task. Available options on equipment and techniques had to be reviewed so that the optimum choice would be made. The excavation had to be controlled, efficient and safe for the personnel involved. It was also important for all equipment to be portable both on the surface and underwater.
A hydraulic power pack is circulating high pressure oil to activate a submersible 3″ pump, which in turn is feeding sea water to a venturi arrangement, creating suction.
Hydraulic tools are widely used in commercial diving applications for their efficiency and reliability.
