Seabed scour is a significant threat to the structural strength of jacket platform.
Hence, it is critical to understand the scour around jacket structure. However, most of
the existing papers mainly focus on the local scour around vertically piled monocylinder
and partially submerged bridge pier. This paper will model 3D scour
development and flow field around jacket structure through numerical investigation
with the aim to investigate the effects of different current velocity on the scour
process. The development of scour will be predicted by the motion of the surrounding
sediment particles using Flow3D’s sediment scour model while the flow field of the
incompressible fluid around the jacket structure will be based on RANS with RNGK- Ɛ
turbulence model closure. It is expected that current velocity will have significant
effects on the scour bed elevation contour, global and local scour depth and the scour
evolution in time.
