FIELD: mining.
SUBSTANCE: invention proposes a disconnection method of a buoy from a mooring turret in a system including a ship containing a mooring turret installed so that it can be rotated on the ship, and a buoy carrying uprising pipelines, which can be attached to the mooring turret and disconnected from it. The system also includes moorings attaching the buoy to mooring points at sea bottom and loading the buoy with mooring forces. Before the buoy is disconnected from the mooring turret, moorings are manipulated so that at least at disconnection the mooring forces are decreased or even disappear. A retaining and releasing device includes a housing with at least two clamps for the mooring, which are located at some distance from each other and made so that an excessive part of the mooring can be located between them. At least one clamp can be installed to the mooring lowering position.
EFFECT: improving reliable and safe performance of a disconnection operation of a buoy from a mooring turret.
