CFD investigations of scour beneath a submarine pipeline with the effect of upward seepage
Li, Yuzhu; Ong, Muk Chen; Fuhrman, David R. (Peer reviewed; Journal article, 2020-12)A numerical model of scour beneath subsea structures considering the effect of upward seepage in the seabed is proposed. A small seepage can cause significant changes to the hydrodynamic force on the bed surface and stability ... -
The effects of slab geometries and wave directions on the steep wave-induced soil response and liquefaction around gravity-based offshore foundations
Li, Yuzhu; Ong, Muk Chen; Gudmestad, Ove Tobias; Hjertager, Bjørn H (Peer reviewed; Journal article, 2019)Gravity-based offshore foundations generally consist of a bottom slab and one or more cylindrical shafts on top of it. The slab geometry can strongly affect the surrounding flow pattern, dynamic wave pressure distribution ... -
Numerical investigation of wave-plus-current induced scour beneath two submarine pipelines in tandem
Li, Yuzhu; Ong, Muk Chen; Fuhrman, David R.; Larsen, Bjarke Eltard (Peer reviewed; Journal article, 2019-12)Two-dimensional (2D) local scour beneath two submarine pipelines in tandem under wave-plus-current conditions is investigated numerically. A fully-coupled hydrodynamic and morphologic model based on unsteady Reynolds-averaged ... -
Random Wave-Induced Momentary Liquefaction around Rubble Mound Breakwaters with Submerged Berms
Celli, Daniele; Li, Yuzhu; Ong, Muk Chen; Di Risio, Marcello (Peer reviewed; Journal article, 2020-05)The effects of submerged berms in attenuating the momentary liquefaction beneath rubble mound breakwaters under regular waves were investigated in a recent study. The present work aims to investigate the momentary liquefaction ...
