Experimental Investigations on Hydrodynamic Responses of a Semi-Submersible Offshore Fish Farm in Waves

Journal of Marine Science and Engineering, 2019
A series of physical model experiments was performed to investigate the hydrodynamic responses of a semi-submersible offshore fish farm in waves. The structural configuration of the fish farm primarily refers to that of the world’s first offshore ...

Influence of Mean Tension on Mooring Line Fatigue Life [PDF]

Volume 2A: Structures, Safety, and Reliability, 2020
Abstract Studies published in recent years have documented a significant mean load effect on fatigue capacity for offshore mooring chain, and show that a reduction of the mean load gives an increase in fatigue life. However, current S-N design curves are based on fatigue tests performed at a mean load of 20% of minimum breaking load (MBL)

Transient Translational–Rotational Motion of an Ocean Current Converter Mooring System with Initial Conditions

Journal of Marine Science and Engineering, 2023
Systems of ocean current power generation are generally moored deep in the seabed. The mooring system is like ropes. The ropes are very long and can provide tension but not compression, and their dynamic displacement is large and unstable, which is ...

Measuring the impact of observations on the predictability of the Kuroshio Extension in a shallow-water model [PDF]

, 2012
In this paper sequential importance sampling is used to assess the impact of observations on a ensemble prediction for the decadal path transitions of the Kuroshio Extension (KE). This particle filtering approach gives access to the probability density of

Coupled dynamics analysis of floating wind turbine mooring system under extreme operating gust

Applied Ocean Research
Extreme operational gust (EOG), defined by sudden increases in wind speed, is one of the most hazardous situations for wind turbines and the mooring system. A coupled aero-hydro-servo-elastic simulation model is developed using a dynamic link library and
