摘要
基于近海风电场快速建造的"大尺度筒型基础的浮运拖航"关键技术以及筒型基础作为边际油田开发的基础形式的背景,同时考虑气浮基础各分舱中水和空气的刚度,推导多分舱筒型基础整体的垂荡和纵摇刚度。建立气浮筒型基础的运动方程,以CBF-3-150海上风电复合筒型基础为例,用数值解法揭示其基础在规则波浪下不同航速和不同波浪入射角对气浮筒型基础运动状态和筒内气垫状态的影响。以理论计算预测筒型基础在规则波下的运动特性。
Based on the background of the key technologies of air-cushion towing of the rapid construction of large-scale bucket foundation in offshore wind farms and the foundation in exploitation of marginal oil fields, the heave and pitch stiffness of whole multi-compartment bucket foundation are deduced considering the water and air stiffness in respective compartment of foun-dation.The motion equations of air-cushion bucket foundation are established.Taking composite foundation CBF-3-150 of off-shore wind turbine as a case, the motion and air-cushion response of foundation are revealed in different towing speed and wave incident angle with numerical calculation.The kinetic characteristics in the regular wave can be predicted according to the previ-ous theories.
