Abstract: At present significant development work is carried out on turret moorings for tanker based Floating Production, Storage and Offloading (FPSO) systems. The paper describes four different turret concepts covering a wide range of requirements. A more detailed outline follows, describing the two turrets designed and installed by SBM Inc., the Rospo Mare external stern turret system and the Jabiru disconnectable riser turret mooring. For the composition of the catenary mooring lines of a turret various components can be applied to optimise its characteristics. This enables the designer of a mooring system to deal with criteria imposed by specific water depth and/or weather conditions. The present knowledge of the hydrodynamic behaviour of moored vessels in waves, wind and current allows a detailed analysis of a mooring system design. The main steps in the analysis procedure are presented. !key1!Mooring Systems !key2! !key3!
