Abstract: This is a support structure for situating and protecting operative devices in deep offshore locations to include certain types of wind turbines. The support structure can be made to submerge and reemerge automatically, with the operative device, to avoid damage that would be caused by hazards in a marine environment at or near the water's surface. Approaching hazards are detected remotely and by sensors located on and around the supporting structure. Critical environmental and support structure conditions are constantly monitored and managed by computer through a network of sensors, equipment controls, and pre programmed response sequencing.
