Abstract: 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.

Abstract: 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.

Abstract: A floating support for off-shore oil production in an arctic or antarctic zone, the support being fitted under its hull with a disconnectable turret from which there extend anchor lines connected to the sea bottom and bottom-to-surface connection pipes. The hull including lateral sides extending in its longitudinal direction. The longitudinal lateral sides of the support carry respective pluralities of devices for localized destruction of pack ice, each device having a destruction tool having at least one pointed portion suitable for breaking pack ice by repeated actuation in vertical pivoting and/or translation of the tool relative to the side, the point, on moving downwards, thus bearing in localized manner against the surface of the pack ice with a force that is preferably at least 10,000 kN. The tool being actuated in pivoting and/or translation with the help of a pivoting and/or translation guide structure applied against the side of the support.

Abstract: 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: a mooring buoy for said anchor lines and first bottom-to-surface connection pipes; and a turret extending within a cavity passing through the entire height of the floating support, said mooring buoy being fastened under the hull of the floating support to said turret; and said floating support being characterized in that it includes a connection/disconnection system for connecting/disconnecting said mooring buoy relative to said bottom wall of the turret, which system comprises: a plurality of hoist cables; and pump means for pumping water out from said valve chamber.
