Background
several FPSO’s in various areas have learnt that they exhibit large roll motions even in operational(day to day) conditions. As the system is not designed for transverse loads and motions, roll motions may lead to significant degradation of safety and efficiency of the operation. In some cases roll motion has resulted in delays and even in production down time. Roll is a resonant motion with large amplitudes due to the small radiation damping. Excitation originates from non-collinear wave current conditions or from combinations of wind driven seas and swells. In such cases even a turret moored FPSO will experience transverse wave loading.

Objectives
FPSO ROLL JIP is to provide means for the reduction of roll motions of FPSO’s. To this end the JIP is aiming at:
· Assessment of the roll behaviour of existing spread moored and turret moored FPSO’s
· Quantification of the dominant factors in the roll response of FPSO’s
· Physical understanding and modelling of roll
· Evaluation of practicalmeans to reduce roll.
