摘要:
海上风电一步式运输安装船由船体和端部两个带有风电整机的大尺度复合筒形基础组成.一步式运输安装船为非自航船, 在运输的过程中通过与拖轮连接提供动力.筒型基础内部布置有分舱板, 在基础内部形成7个舱室.拖航过程中, 对筒形基础舱室内部充气使其起浮, 与船体凹槽处顶盖板紧密接触.通过模型试验测定了两者之间的竖向压力以及拖航时船体的运动响应.试验结果表明:舱室内气压的大小会影响到筒型基础与船体接触力的变化及船体的稳性, 即气压大时, 筒型基础与船体接触力大, 船体的稳性较好; 气压小时, 筒型基础与船体接触力小, 船体的稳性较差.
Abstract:
The integrated transportation and installation vessel for offshore wind turbine consists of the vessel and two large composite bucket foundations with towers and upper wind turbine configurations. The integrated vessel is non-self-propelled and should be towed by tugboats. Seven compartments are formed in one large composite bucket foundation using bulkheads. And the compartments are air charged and floated and then the bucket foundations are connected with the vessel tightly. The vertical pressure between the vessel and the bucket foundation and the motions of the integrated transportation and installation vessel are investigated. Test results show that the air pressure in the bucket foundations affects both the pressure between the vessel and the bucket foundation and the stability of the vessel. The pressure is larger and the vessel is more stable with the increase of air pressure.
