Description

An experimental investigation on the motions and mooring forces of a typical internal turret moored Floating Production Storage and Offloading (FPSO) system under regular sea waves for different loading conditions i.e., 40%DWT, 70%DWT and 100%DWT with different turret locations viz forward, midships and semi- aft positions is reported in this paper. A 1:100 scale model of 140000 DWT turret moored FPSO system was tested in a 2m wide wave flume at a water depth of 1m for the wave frequencies from 0.55Hz to 1.25Hz in steps of 0.04Hz. The motions were measured by rotary type potentiometers and proving ring type load cells were used to measure the mooring forces. From the analysis of the experimental results, it is found that among the three turret locations, the forward turret position is the best suited position for the internal turret moored FPSO system, so as to have favourable and safe working environment. In this turret location, the surge, heave and pitch motions are about 20% to 30% less in comparison with mid ship and semi-aft positions for all loading conditions.
