FIELD: transportation.
SUBSTANCE: inventions relate to a vessel comprising an anchor structure, to a buoy locking system, and to an anchor assembly comprising: an anchor buoy (6) with a central axis, an upper ring part (200) forming an upper thrust surface (202); an anchor structure (3) comprising a cavity (5) with a wall, and made with the possibility of accepting the anchor buoy (6) and a buoy locking system (7) located next to the cavity (5) to communicate with the upper ring part (200) for locking the anchor buoy (6) to a turret anchor structure (6) and comprising at least two locking devices (10) attached to the anchor structure (3). Each locking device (10) has a locking pawl (106) attached to an element (110) creating a force for the axial displacement and the application of a force directed upwards to the upper thrust surface (202). The anchor buoy (6) comprises a lower thrust surface (203) located at an axial distance from the upper thrust surface (202) beneath it. The locking system (7) comprises an interaction element (107, 208) located axially below the locking pawl (106) and designed to interact with the lower thrust surface (203) and applying thereto a force directed downward. The buoy in places (201) located axially above the upper hard surface (202) is with axial clearance (D) from the wall cavity, so that the axial forces acting on the buoy are transferred to the turret anchor structure (6) substantially only in the locations of the locking pawls (106) and the interaction element (107, 208).
EFFECT: reducing the load on the locking device and the effectiveness of applying a waterproof seal between the buoy and the cavity wall of the anchor point.
