A turret assembly for a vessel comprises a moonpool defined in the vessel and a turret structure rotatably mounted in said moonpool. The turret structure comprises a turret table which by means of a main bearing is rotatably mounted in said moonpool and a hollow turret shaft defined by a surrounding shaft wall, which turret shaft has an upper shaft end connected to the turret table, a substantially cylindrical shaft part that extends downwardly from the turret table and a lower shaft end provided with means intended for cooperation with a lower bearing. The shaft wall of the upper shaft end comprises a widened part surrounding the cylindrical shaft part and defines a circumferential crest, wherein the shaft wall of the upper shaft end, starting from said circumferential crest, extends downwardly towards a position where the upper shaft end is connected to the turret table.
