Proper lubrication for the pivot point of an anchored oil tanker to a vessel enables able safe rotation around up and down movements in accordance with the wave movements.
The turret is the main assembly of the whole vessel, and it is the pivot point where the vessel is able to rotate during the mooring. Most turrets are currently manufactured using bearings up to 8 meters. Due to the high demand for faster oil extraction, vessel builders have to increase above 8 meters. Bearings above 8 meters in diameter are hard to come by and can be very expensive. New technology has emerged by using large-diameter cylinders of approximately 20 meters. The cylinders are held in place by bogies. These bogies are lubricated with grease pads at both the radial and axial wheels.
