<p>A turret for a vessel such as a drilling or production vessel for recovery of oil offshore, is installed in such a manner that it can rotate in a throughgoing opening or well in the hull of the vessel, and includes bearing arms (15) which are equipped with axially and radially fitted bearing elements which act against corresponding bearing elements on the vessel. The bearing arms (15) are connected to a substructure in the turret which provide individual suspension to and can absorb unevennesses and deformations in the bearing. Further, the axial bearing track is disposed on a pedestal-like elevated area (30, 47, 56, 57, 58) which is rigid in the axial direction. The pedestal-like elevated area is connected with the hull, mainly at the level of the neutral axis of the vessel, and the radial bearing element on the vessel is in the form of a band-like structure (52, 61).</p> |
