... ABSTRACT Ship Integrated Turret (SIT) is widely used for FPSO in harsh environment and deep water applications. In China, all FPSOs located in South China Sea are equipped with Ship Integrated Turret mooring systems. In 2019-2020, CNOOC has developed offshore Liuhua16-2 oil field project...

... field. The turbulence model is DDES, and the cavitation model is the Schnerr-Sauer model. The sound field is predicted by the FW-H formulation. Unlike the traditional method, this paper solves the quadrupole term (non-linear term) by direct volume integration, so the nonlinear term can be predicted more...
