NUMERICAL STUDIES ON THE GAP RESONANCE OF FPSO AND SHUTTLE TANK SIDE BY SIDE DUE TO OCEAN EXCITING WAVES

This research is proposed to study the gap resonance of FPSO and shuttle tank in side
by side arrangement due to exciting waves. During the side by side arrangement, there
are a gap distance between the FPSO and shuttle tank which resonance might occurs.
This resonance can increase the wave height in the gap distance that can disrupt the
arrangement side by side of FPSO and shuttle tank. This study is crucial because the
FPSO and shuttle tank in this arrangement is designed to undergo the offloading
operation. If these arrangement is disrupted due to the resonance, the effectiveness of
the offloading operation will reduce as well as the safety of the crew because the FPSO
and shuttle tank might be colliding. Thus, the ability of the FPSO and shuttle tank to
maintain the arrangement and gap distance will be the significant factor in obtaining
the effectiveness of the offloading operation and safeness. The simulation of the FPSO
and shuttle tank in the Star CCM+ software will be done to analyse the gap distance
and drafts of two floating bodies on the resonance. Furthermore, this study also aims
to analyse the dynamic response and environmental loading on these two floating
bodies.
