An oil production floating support including a disconnectable mooring system for anchor lines to the sea bottom and for bottom-to-surface connection pipes. The floating support comprises a mooring buoy for mooring lines and bottom-to-surface connection pipes, the buoy preferably being an annular buoy. The floating support being characterized in that said turret has a watertight tubular outer structure having a bottom wall assembled in watertight manner to the bottom end of the watertight tubular outer structure. The tubular outer structure contains an inner structure secured at its top end to the hull. The inner and outer tubular structures co-operate with at least one bottom rolling or friction bearing, enabling the inner structure to turn, with the outer structure not being caused to turn when the floating support is caused to turn about a vertical axis ZZ' of the cavity and of the watertight tubular outer structure. The bottom rolling or friction bearing being situated beneath the surface of the water, but inside said watertight outer structure.

Floating support fitted with a turret including rolling bearings protected from water

An oil production floating support having a mooring device for mooring anchor lines anchoring to the bottom of the sea and bottom-to-surface connection pipes. The device has two mooring buoys having the anchor lines and the bottom-to-surface connection pipes moored respectively thereto. The said two mooring buoys being connectable and disconnectable to a turret under which they are fastened, independently of each other.

Floating support comprising a drum equipped with two buoys to which to fasten tethers and pipes connecting between the sea bed and the surface

The present invention relates to an oil production floating support having a releasable mooring system of anchor lines to the sea bottom and of bottom-surface connection pipes, the support comprising:
