Research on the Dynamic Performance of a Novel Floating Offshore Wind Turbine Considering the Fully-Coupled-Effect of the System

open access: yesJournal of Marine Science and Engineering, 2022
Floating offshore wind turbines (FOWTs) still face many challenges in improving platform stability. A fully submersible FOWT platform with inclined side columns is designed to tackle the current technical bottleneck of the FOWT platform, combining the ...

Building Resilient Coastal Communities: The NHERI Experimental Facility for Surge, Wave, and Tsunami Hazards

open access: yesFrontiers in Built Environment, 2020
Through the Natural Hazards Engineering Research Infrastructure program (NHERI) established by the National Science Foundation in the United States, a suite of experimental facilities has been made available to the research community to advance the ...

Statistical Analysis of the Stability of Rock Slopes

open access: yesJournal of Marine Science and Engineering, 2019
Physical model tests were performed in a wave flume at Deltares with rock armoured slopes. A shallow foreshore was present. At deep water, the same wave conditions were used, but by applying different water levels, the wave loading on the rock armoured ...

Validation and Comparisons of Methodologies Implemented in a RANS-VoF Numerical Model for Applications to Coastal Structures

open access: yesJournal of Marine Science and Engineering, 2022
Methodologies to be used in numerical models based on Reynolds-averaged Navier–Stokes (RANS) equations and the volume of fluid (VoF) to deal with waves over coastal structures, which involve wave breaking and overtopping and porous structures, are shown ...

The Integration of Coastal Flooding into an ArcFLOOD Data Model [PDF]

open access: yes, 2014
With the impact of global climate change, the speedy, intelligent and accessible dissemination of coastal flood predictions from a number of modelling tools at a range of temporal and spatial scales becomes increasingly important for policy decision ...

Effect of Variations in Water Level and Wave Steepness on the Robustness of Wave Overtopping Estimation

open access: yesJournal of Marine Science and Engineering, 2020
The wave overtopping discharge at coastal defense structures is directly linked to the freeboard height. By means of physical modelling, experiments on wave overtopping volumes at sloped coastal structures are customarily determined for constant water ...

Seasonal changes in beach resilience along an urbanized barrier island

open access: yesFrontiers in Marine Science, 2022
Beach width, dune height, and vegetation coverage are key parameters to assess beach resistance and resilience to storms. However, coastal development often causes beach ecosystem degradation due to poor coastal management.

Numerical study of spudcon penetration on two-layered soil with Lagrangian-Eulerian couple [PDF]

open access: yesفناوری‌های پیشرفته در بهره‌وری آب, 2023
IntroductionJackup rigs are one of the most widely used and popular offshore structures in semi-deep waters due to their mobility. The new jackups usually consist of a floating triangular body supported by three independent vertical truss legs that can ...

Dynamic Behavior of Sand Bed under Oscillating Water Pressure [PDF]

open access: yes, 1986
Under the attack of storm waves, there are many destructions of coastal structures in the forms of sinking and sliding. These types of destructions will be in close relation to the dynamic behavior of sand bed around the structures.

Reflections from Coastal Structures

open access: yesCoastal Engineering 1988, 1988
Wave reflections at and within a coastal harbour may make a significant contribution to wave disturbance in the harbour. Reflected waves may lead to danger to vessels navigating close to structures, and may reduce the availability of berths within the harbour. Wave reflections may also increase local scour or general reduction in sea bed levels. In the
