Seepage force induced by ocean waves has been related to the liquefaction around submarine structure, and it shown cause significant sediment transport rapid burial of pipelines objects (Tsai et al., 2022). This study assesses impact momentary soil due pore pressure gradient near seabed generated in range oceanic coastal environment. The nonlinear wave solution stream function numerical approxi...

This study investigated the behavior of spudcan foundation jack-up vessels offshore wind turbines during undrained vertical penetration into thin stiff-over-normally consolidated clay. Large deformation finite element (LDFE) analyses were used to simulate continuous seabed surface. Detailed parametric analysis was performed explore a range normalized soil properties and layer geometry roughness...

Georges Bank is a large, shallow feature separating the Gulf of Maine from the Atlantic Ocean. Previous studies demonstrated a strong tidal-mixing front during the warm season on the northern bank margin between thermally stratified water in the Gulf of Maine and mixed water on the bank. Tides transport warm water off the bank during flood tide and cool gulf water onto the bank during ebb tide....

Marine controlled source electromagnetic (CSEM) sensing method used for the detection of hydrocarbons based reservoirs in seabed logging application does not perform well due to the presence of the airwaves (or sea-surface). These airwaves interfere with the signal that comes from the subsurface seafloor and also tend to dominate in the receiver response at larger offsets. The task is to identi...

abstract infiltration process is one of the most important components of the hydrological cycle. on the other hand, the direct measurement of infiltration process is laborious, time consuming and expensive. in this study, the possibility of predicting cumulative infiltration in specific time intervals, using readily available soil data and artificial neural networks (anns) was investigated. for...

Within the framework of linear theory, applicable far from the shore, we investigate the two-dimensional propagation of waves generated in the ocean by a sudden seabed deformation.

A solution is developed for the buildup, steady, and postarrest dissipative pore fluid pressure fields that develop around a conical penetrometer that self-embeds from free-fall into the seabed. Arrest from free-fall considers deceleration under undrained conditions in a purely cohesive soil, with constant shear strength with depth. The resulting decelerating velocity field is controlled by soi...

This paper undertakes liquefaction analysis with simplified procedures standard penetration test (SPT) data and cone (CPT) obtained from an offshore wind farm in the Changhua area. The soil resistance calculated by SPT-based procedure suggested Japan Railway Association was agreement laboratory results. CPT is widely used site investigation of farms. However, Taiwan’s registered professional en...
