... factor to be evaluated for long-term operation of more than 20 years of service life. The maximum roll motion angle below 6.5° in the 100-year return storm conditions makes normal process production possible in 100-year return design conditions, reducing the frequency of production shutdowns. Reduced...

... of stationary vessels, and existing studies on this have focused on single row cargo tanks which is seldom the case in FPSOs. The aim of this paper is to study roll motion coupled with sloshing in partially-filled pair of two-row tanks of a stationary FPSO model exposed to regular beam waves. The model tests...

... and the roll motions of the FPSO are a key parameter. The roll motions may induce large vertical displacements at the top of the risers which affect the ultimate strength of the flexible pipe as well as fatigue of end- fittings. Moreover, the vertical motions and accelerations may induce compression...

The roll motions of both the turret-moored floater and the LNG shuttle carrier are mainly determined by the approach angle of the long-period swell. The use of thruster...

INTRODUCTION Semisubmersible platforms and large volume floating structures are usually designed in such a way that their heave, pitch and roll motions due to first order wave forces shall be minimum. The most important component in the motions of such platforms is in many cases the resonant...

To outline possible ways, we must revert to the basic dynamics of the motions of a floating offshore platform, in this case a semi submersible. The uncoupled roll motion of a ship is governed...

In order to correlate with theoretical results, which do not include the effect of jacket leg submergence during motions, tests were conducted with and without jacket leg submergence...

... ABSTRACT The performance of offshore work from floating platforms dictates the desirability of "minimum motions". One of the motions that is most troublesome, especially is the case of ship-shaped or barge-shaped platforms, is the roll motion because of the large amplitude and relatively large...
