Turret refers to the rotating function of the large equipment to facilitate the rotation of the vessel according to winds, waves and dominating current while the risers remain connected to a fix part on the seabed. Whereas, the turret is the main component of a vessel or any floating production unit to which the risers coming from the seabed are connected. Moreover, the turret system contains a bearing system which helps the vessel to rotate around the fixed geostatic part of the turret, which is attached to the mooring system.
