Effect of Various Mooring Materials on Hydrodynamic Responses of Turret-Moored FPSO with Emphasis on Intact and Damaged Conditions

The behavior of different mooring line materials has a significant influence on the system and, consequently, dynamic responses floating platform. Although there have been previous studies FPSOs and their systems, failure scenarios associated with received less attention, particularly for turret-moored taut moorings. Thus, this paper investigates in intact, single-line, double-line damaged conditions hydrodynamic FPSO, restoring behavior, mooring, riser tensions considering wave Gulf Mexico. Mooring lines including Aramid, HMPE, polyester, steel wire were considered middle segment, which was segment interest study. forces found to increase increasing stiffness, higher stiffness resulted loss force case single-line failure. In all cases, submerged weight material had responses, tension, transient especially ability resist Each observed behave differently each degree freedom (DOF), showing necessity pay close attention selection specific objectives.
