Behaviour of water column inside turret and annular space of FPSO vessel

The water column inside the turret of an FPSO typically undergoes sloshing due to speed as well as wave effects. Sloshing can have detrimental effects and therefore needs to be investigated and minimized. Sloshing occurs at the free surface region. As a result of sloshing, the volume of entrapped water in the turret of an FPSO increases and its acceleration due to the ship's motions induces inertia loads, which could affect the overall balance of the loads in the system. This paper analyzes the behavior of the water column inside the turret and annular space of an FPSO vessel subjected to different sea conditions. The results from CFD simulations have been compared with experiments.
