Numerical Study for Wave-Induced Oscillatory Seabed Response Around Pile Foundations Using OpenFOAM
International Journal of Offshore and Polar Engineering, 2019In this paper, a three-dimensional numerical model for wave–seabed interactions around a group of pile foundations is proposed. Unlike in previous studies, both wave and seabed submodels are developed based on the open source library OpenFOAM (version 4 ...

A Study of Ping-To-Ping Coherence of the Seabed Response
2002Coherence in acoustic backscatter is used to perform reverberation based micronavigation in SAS imaging. To evaluate limits of ping-to-ping coherence, this paper examines how interface characteristics and acoustic source parameters influence ping-to-ping signal stability.

Sedimentology, 2016
AbstractThe widely recognized global phenomenon of wave–seabed interactions and the resulting secondary stratification processes are complex and poorly understood. To better understand the mechanisms by which the differentiation between fine‐grained and coarse‐grained materials occurs and how new sedimentary sequences form, laboratory flume experiments

A 3D numerical analysis of wave-induced seabed response around a monopile structure
Geomechanics and Geoengineering, 2019Despite the numerous ideas concept for an offshore wind turbine foundation, the monopile foundation is the most widely adopted concept in engineering practices.

Response of Cross‐Anisotropic Seabed to Ocean Waves
Journal of Geotechnical Engineering, 1992Quasi‐static field equations for fully saturated porous elastic media, based on Biot's theory (1972‐1973), established in the writer's previous works (1989‐1990) are used in order to describe the behavior of such materials under wave ocean loading. A brief description of cross anisotropy with a vertical axis of symmetry (orthotropy) is given.

Effect of wave non-linearity on the standing-wave-induced seabed response
International Journal for Numerical and Analytical Methods in Geomechanics, 2000Summary: A standing wave in front of a seawall may reach a height more than twice of its incident component. When excess pore pressure occurs, it may even induce seabed instability, hence endangering the structure. This issue was studied previously using only linear wave theory.

The Limits of Responsibility: Liability for Damage in the Deep Seabed?
2019This contribution seeks to discuss the limits of state responsibility as they are witnessed in the topic of international liability. The first part addresses the intersection between responsibility and liability using as a reference point the work of the International Law Commission.

Updated Free Span Response Near the Seabed
Volume 2: Subsea Technology; Ocean Space UtilizationAbstract Most offshore pipelines, umbilical’s, and cables installed exposed on the seabed may exhibit free spans. These slender circular cylinder structures, when subjected to external flow, may experience vortex-induced vibrations (VIV), potentially leading to significant fatigue damage.
