摘　　要：针对目前海上风机运输安装风险较高、成本较大和安装周期较长的问题,本文主要研究了一种新型海上风电安装船的改造工艺及运动学、动力学特征。其中改造工艺主要针对半潜驳船进行改造,通过船艏安装“搭接装置”和导管架,并灵活调配船艉锚碇、压载水及系泊缆的方式,确保海上风机安装符合规范标准。本研究首先基于势流理论进行运动学和动力学的研究,采用水动力分析软件AQWA建立风电安装船的频域-时域模型。然后,通过峰值响应来验证数值模型的准确性,并为实海况作业提供试验数据。最后,采用AQWA软件对工作海域下不同影响因素进一步分析,探究风速、风浪流角度和波浪周期等参数对作业工况的运动学和动力学响应。研究结果表明,在中国近海海域的环境条件下,采用搭接安装方法时,船体的运动与动力响应幅值较小,适合风机安装,这也表明此种改造方法具有工程应用价值。进一步分析发现:船体的响应幅值受风速的影响较小;而风浪流角度会对安装船的响应幅值产生较大影响,即当迎浪方向幅值较小时,横浪与顺浪方向幅值较大;此外,随着波浪谱峰周期由6 s增大到10 s,其响应幅值也越来越大。因此,为确保工程作业的安全和效率,应尽量避免在横浪以及较大周期的海况下作业。This paper mainly studies the transformation technology,kinematics and dynamics characteristics of a new offshore wind turbine installation ship.The transformation process is mainly for the semi-submersible barge,through the installation of“lap joint device”and jacket platform on the bow,and the deployment of anchor,ballast water and mooring cable on the stern,to ensure that the installation of offshore wind turbines meet the requirements of the specification.Research on kinematics and dynamics based on potential flow theory and establish frequency domain-time domain model of wind power installation ship by using hydrodynamic analysis software AQWA to verify the numerical model and provide test data for real sea state operation through peak response;finally,further analyze different influencing factors under the working sea area with AQWA,including exploring the kinematic and dynamic response of wind speed,wind wave current angle,wave period and other parameters to the working conditions.The results show that the lapping installation method is suitable for the installation of wind turbines due to its small amplitude of motion and dynamic response of the hull under the environmental conditions in the offshore waters of China.It also shows that this reform method has engineering application value.The response amplitude of the hull is less affected by the wind speed;the angle of wind,wave and current will have a greater impact on the response amplitude of the installation vessel,the amplitude in the direction of facing wave is smaller,while the amplitude in the direction of beam wave and following wave is larger;as the peak period of wave spectrum increases from 6 s to 10 s,the response amplitude becomes larger and larger.Beam waves and sea conditions with large periods shall be avoided as far as possible during engineering operations.
