| Abstract | A 11el type of foundation, a high-rise pile cap structure, was proposed to support offshore wind turbines in China. It is unique because the upper cap is now and then partially submerged or totally exposed in the air. The wave force of this unique structure is not well understood yet. In this paper, a fully nonlinear numerical wave tank is established to deal with this problem based on Navier-Stokes equations and volume of fluid technique. The wave impact loads on the structure and their mechanism are revealed. Modifications of the cap bottom elevation are considered to explore its influence on direct and indirect wave impact loads on the lower piles. The wave impact load on the most dangerous pile is detected high if the cap bottom is at the still water level or close to the wave crest level, and small impact load is found while the cap bottom is at the height of half wave crest. Attempts of structural improvement are considered to reduce the wave impact loads on the piles. The wave impact load can be notably reduced by opening air vents in the cap together with lifting the bottom of the inner part of the cap. |
