Influence of Model Simplifications Excitation Force in Surge for a Floating Foundation for Offshore Wind Turbines

open access: yesEnergies, 2015
As offshore wind turbines move towards deeper and more distant sites, the concept of floating foundations is a potential technically and economically attractive alternative to the traditional fixed foundations.

WAVE FORCES AGAINST SEA WALL

open access: yesCoastal Engineering Proceedings, 1964
The study concerning the wave forces acting on breakwater has been conducted by numerous scientists and engineers both in field and in laboratory,, While few studies have been carried out on the wave forces acting on sea wall which is located inside the surf zone.

Wave Forces on Offshore Pipelines

open access: yesCoastal Engineering 1980, 1980
Transportation of offshore oil and gas is mostly carried out by means of offshore pipelines. Depending on the ocean environment these pipelines are either buried or made to rest on the ocean bed or placed on excavated trenches. In cases where the sea bed is mostly of rock, pipelines can be laid on the bed and anchored to the ocean floor by suitable ...

Effects of imperfect angular adjustment on plasmonic force

open access: yes, 2017
The attractive plasmon force between two metallic walls when the electromagnetic wave propagates through a narrow slit has been studied earlier for parallel plates and normal incidence.

Nonlinear Wave-Induced Uplift Force onto Pipelines Buried in Sloping Seabeds

open access: yesApplied Sciences, 2023
In this paper, a two-dimensional numerical model for wave-seabed-pipeline interaction is developed to examine the wave-induced uplift force onto pipelines buried in sloping seabeds.

Spin-Orbit and Tensor Forces in Heavy-quark Light-quark Mesons: Implications of the New Ds state at 2.32 GeV

open access: yes, 2003
We consider the spectroscopy of heavy-quark light-quark mesons with a simple model based on the non-relativistic reduction of vector and scalar exchange between fermions.

WAVE FORCES ON SUBMERGED OBJECTS

open access: yesCoastal Engineering Proceedings, 1976
Limitations of the Morison equation for computing wave forces on small submerged structures have encouraged the use of dimensionless relationships containing only height, period and water depth. However in dividing the force by the theoretical drag force or inertia force a relationship can be found with the Keulegan parameter (U. T/D) over a wide range
