INVESTIGATION OF CHARACTERISTICS OF CURRENT UNDER HIGH WAVES IN THE OFFSHORE KITA-KYUSHU

Abstract

 In the offshore area of Kita-Kyushu city, experimental study for reasonable planning/designing of the offshore wind power generation facility has been in progress. At the wind observation tower in the site, continuous observation of wind, wave, and current has been carried out since 2012 and accumulated data under various sea conditions. In the study area, complicated currents are generated under high wave condition combined with wave induced current, wind driven current, and strong tidal current passing through Kanmon Straits. In this study, numerical simulations of current under high wave have been carried out and examined the characteristics of current by extracting wind driven current.
