In this study, a wear amount estimation method is investigated using the data obtained from 2nd Demonstration Experiment of wind observation system off coast Sakata, floating platform including mooring to reduce optimized by method. First, condition lines and it found that at point on buoy side largest. Next, cause higher progress than expected design speed numerical calculations, confirmed pro...

In recent years, there have been a growing number of online social platforms which allow users to publish and share their personal stories, opinions, knowledge, expertise, and product reviews. Online service switching has become a major challenge for marketers. In this study, we attempt to understand online service switching behavior through investigating blog service switching. We use the push...

Abstract This paper establishes the computational fluid dynamics models of marine submersible buoy system. The use incompressible Navier-Stokes equations, Renormalization-Group (RNG) turbulence model and fractional areas/volume obstacle representation method. Using lumped mass mothed to simulate anchor line power supply cable. result show that great tension forces increase occurs at moment when...

Globally, the Celtic Sea shelf break is ranked highest as an energetic ‘‘hot spot’’ of tidal energy conversion, therefore making it the most significant contributor to global internal tidal energy flux. In this paper, the three-dimensional dynamics of baroclinic tides in the shelf-slope area of the Celtic Sea was investigated numerically and using observational data collected on the 376th cruis...

Recently, several experimental and numerical studies have underlined the advantages of adding clumped weights at discrete positions mooring lines. To confirm influence these weights, an study was performed for a 1:30 scale model line. In this study, weight is modeled as scaled disc placed different along The series experiments has been carried out CEHIPAR towing tank using submerged studless ch...

The objective of this paper was to present the modeling and optimization mooring lines for floating offshore wind turbines (FOWT) located in various water depths from 50 m 100 Taiwan western areas. A semi-submersible turbine system is considered based on Offshore Code Comparison Collaborative Continuation (OC4) DeepCwind platform with National Renewable Energy Laboratory (NREL) 5-MW baseline tu...
