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 ax- ially 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 deforma- tions 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 ves- sel, and the radial bearing element on the vessel is in the form of a band- like structure (52,61).
