Abstract
The invention relates to a vessel having a turret which is rotatingly mounted within a turret wall. The turret is supported by means of a number of axial bogie wheels. The bogie wheels have a curved metal contact surface with a radius of curvature within 5 and 50 meters, preferably of about 20 meters. The wheel diameter amounts to about 750 mm. The wheels run on circular raceways with a diameter of between 10 and 30 m, preferably about 20 meters. It was found that the bogie wheels have low friction, very little wear and are hardly subject to torsional forces upon rotation.
