摘要
为了解决海洋强风场特性研究中实测数据不足的问题,在我国南海流花4-1油田一座半潜式平台上,开展了近海面风场特性的实测研究工作.对2011-09-22实测数据开展了分析,获得了南海近海面风场的湍流强度、阵风因子和湍流积分尺度等强风特性参数;同时开展了脉动风功率谱的拟合研究工作,将实测谱与Davenport谱、von Karman谱和Kaimal谱进行比较,证明了von Karman谱在近海面强风环境中拟合结果较优.
To solve the problem of lacking prototype data in study of strong sea wind characteristics,aprototype measurement work for wind characteristics near sea surface is carried out on a semisubmersible platform in LH4-1 oil field in South China Sea.The data collected in the day,22 September 2011,is analyzed to obtain wind characteristic parameters near sea surface,such as turbulence intensity,gust factor and integral scales of wind turbulence,etc..Fluctuating wind power spectrum is also calculated by prototype data.The measured spectrum is compared with Davenport spectrum,von Karman spectrum and Kaimal spectrum.The comparative results show that for the strong wind near sea surface von Karman spectrum fits the measured spectrum best.
