Difference of tension on mooring line by buoy type

Journal of the Korean society of Fisheries Technology, 2014
The difference of mooring tension by type of buoy was investigated in the circulating water channel and the wave tank for deducting the most stable buoy from the current and the wave condition. 5 types of buoy made up of short cylinder laid vertically (CL-V), short cylinder laid horizontally (CL-H), capsule (CS), sphere (SP) and long cylinder (CL-L ...

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
