Abstract: Turret is the common mooring scheme and the key part of the floating production storage and the offloading (FPSO), whose ventilation system requires to be focused on. Most of the technologies and patents of the turret are currently mastered by a few foreign companies, imposing a long-term technological blockade on China. This paper proposes the design scheme of the ventilation system of the FPSO in detail, and carries out the numerical simulation by the computational fluid dynamics (CFD). This design scheme innovatively utilizes the bearing wheel gap and the opening of the turret itself for the forced ventilation, which realizes the effective ventilation of the turret. The design scheme and the analysis method have the accumulated valuable experience, which are of great significance to China’s independent design of the FPSO turret in the future.
