Underwater structure and underwater structure installation and removal method
The submersible structure comprising a hollow floodable frame (2, figure 4) & a plurality of hinged stability tubes 3, 4 mounted to the frame. The tubes are stowed horizontally on the frame when the frame is not immersed in water and raised under their own buoyancy when the frame is being sunk or raised in the body of water. Preferably the stability tubes revert to a horizontal position when the floodable frame is placed on the bed of the body of water. Also disclosed are valves which permit the flow of water when the water is above a predetermined level and impede the flow of water through a valve when the water is below the predetermined level. The invention also provides a method of placing & retrieving a submersible structure using stability tubes.
