FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to the field of geological exploration and offshore drilling and concerns the setting of a drilling vessel at anchorage at the point of drilling. Proposed turret of the drilling vessel contains the upper part and the lower part, which is a buoy with a control system for buoyancy, connected to the lower part of the anchor system and attached to the upper part of the turret using hydraulic locking devices made with the possibility of lowering and lifting to grip the response parts of the anchor chains, the chains of the holding anchor system are attached to the upper part of the turret on the winch drums using hydraulic tensioning devices.
EFFECT: technical result consists in improving the operational characteristics of the device due to the possibility of individual adjustment of the tension of each of the chains of the anchor system and the possibility of reverse connection of the buoy without using auxiliary vessels.
