Seasonal and migrational weight changes in Dunlins
In eastern England, Dunlin weights peak in December. Is this because food is abundant then, or an ‘insurance’ against cold weather to come? Such early winter weight peaks do not occur in south-western Britain, and the implications of this are discussed.
This study investigates the effects of Pierson-Moskowitz, Jonswap spectrum that are typical irregular wave spectrums for wind turbine system with jacket support structure. Also various offshore environmental parameters based on korean local condition were used in our study. The loads acting on the system was considered by referring to the Design Load Case from IEC guide line. And improved von Karman model was used as a turbulence model. As a result, various significant wave height and peak spectral period cause noticeable difference of extreme and fatigue loads prediction.
