Description
技术领域technical field
本发明涉及海上浮动式风力机的整体安装技术，具体涉及一种张力腿式海上浮动式风力机整体安装辅助装置及安装方法，属于海洋工程技术领域，The invention relates to the overall installation technology of an offshore floating wind turbine, in particular to a tension leg type offshore floating wind turbine integral installation auxiliary device and an installation method, belonging to the technical field of marine engineering.
背景技术Background technique
风能是目前发展最迅速、最具潜力的可再生能源，全球可利用的风能资源非常丰富，风能总量比地球上可开发利用的水能总量大10倍以上，其中大部分高品质的风能资源集中在海上深水区域。海上风能大国如：美国、中国、日本、挪威等的风能资源都集中在水深超过30m的非浅水区域。深水浮动式风力机作为一种替代传统固定式风机的新装备具有广阔的应用前景，已成为国外海上风能研究的热点领域。美国、欧洲和日本等对此进行了比较广泛的研究，纷纷提出了新型的浮式风机概念，目前处于不同的设计和验证阶段。Wind energy is currently the fastest growing renewable energy with the greatest potential. The world’s available wind energy resources are very abundant. Resources are concentrated in deep water areas offshore. The wind energy resources of major offshore wind energy countries such as the United States, China, Japan, and Norway are all concentrated in non-shallow water areas with a water depth of more than 30m. As a new equipment to replace traditional fixed wind turbines, deep-water floating wind turbines have broad application prospects and have become a hot field of offshore wind energy research abroad. The United States, Europe and Japan have conducted extensive research on this, and have proposed new concepts of floating wind turbines, which are currently in different stages of design and verification.
浮动式风力机主要由三部分组成，即位于顶部的风力发电机组、底部的浮式基础和用以连接二者的塔筒结构。底部的浮式基础与海洋石油平台下浮体相似，可划分为三种主要类型：单柱式平台，半潜式平台和张力腿式平台。单柱式平台通过压载使重心高度远低于浮心高度以获得稳性和优良的垂荡性能。半潜式平台通过合理布置水线面以取得较大的水线面惯性矩，从而获得稳性和较好的运动性能。张力腿式平台通过设置张力腿预张力以获得稳性和优良的运动性能。The floating wind turbine is mainly composed of three parts, namely the wind turbine at the top, the floating foundation at the bottom, and the tower structure used to connect the two. The floating foundation at the bottom is similar to the floating body under the offshore oil platform, and can be divided into three main types: single column platform, semi-submersible platform and tension leg platform. The height of the center of gravity of the single-column platform is much lower than the height of the buoyancy center through ballasting to obtain stability and excellent heave performance. The semi-submersible platform obtains a larger moment of inertia on the water plane by rationally arranging the water plane, so as to obtain stability and better motion performance. The tension leg platform obtains stability and excellent motion performance by setting the tension leg pretension.
目前，海上浮动式风力机的安装方式主要分为多体式安装、两体式安装和整体式安装。分体式是指依次安装机舱、轮毂、叶片、塔筒和浮动式基础等，其安装过程比较复杂，每次安装需要海上吊装的次数较多，需要较长的海上作业时间，因此对安装船的要求高，安装费用也较高。两体式安装是指在陆地上把顶部的风力发电机组(包括机舱、轮毂和叶片等)和塔筒安装好，再利用安装船吊运至预先安装好的海上浮动式基础上。整体式安装是利用现有技术和装备在陆地上完成海上浮动式风力机所有部件的安装，再利用安装船整体运输至预定安装海域，最后再安装系泊系统。At present, the installation methods of offshore floating wind turbines are mainly divided into multi-body installation, two-body installation and integral installation. The split type refers to the installation of the engine room, hub, blade, tower and floating foundation in sequence. The installation process is more complicated, and each installation requires more sea hoisting and longer sea operation time. Therefore, the installation ship The requirements are high and the installation cost is also high. The two-piece installation refers to the installation of the top wind turbine (including the nacelle, hub and blades, etc.) and the tower on land, and then use the installation ship to lift it to the pre-installed offshore floating foundation. Integral installation is to use the existing technology and equipment to complete the installation of all components of the offshore floating wind turbine on land, and then use the installation ship to transport the whole part to the intended installation sea area, and finally install the mooring system.
经对现有技术的文献检索发现，上海交通大学船建学院于2012年公布一种新型的多立柱张力腿式海上5MW浮动式风力机(Energies 2012,5,3874-3891；doi:10.3390/en5103874)，其浮动基础主体型深21.5m，中心立柱直径6m,周向立柱截面尺寸长4.8m，宽4.8m，排水体积4170m3，平台重量包括固定压载约为2375t，浮心位置位于水面下约12m处，重心位置位于水面下约9.85m处。由于该5MW海上张力腿式海上浮动式风力机浮心位于重心位置以下，在未安装张力系泊腿之前，整体稳性不足，因此安装时不宜采用整体式安装，只适合采用分体式安装或两体式安装，因而安装成本较高。A literature search of existing technologies found that Shanghai Jiao Tong University School of Shipbuilding announced a new multi-column tension leg offshore 5MW floating wind turbine in 2012 (Energies 2012,5,3874-3891; doi:10.3390/en5103874 ), the main body of the floating foundation is 21.5m deep, the diameter of the central column is 6m, the section size of the circumferential column is 4.8m long, 4.8m wide, and the drainage volume is 4170m 3 . At about 12m, the center of gravity is located at about 9.85m below the water surface. Since the buoyancy center of the 5MW offshore tension leg type offshore floating wind turbine is below the center of gravity, the overall stability is insufficient before the tension mooring legs are installed. One-piece installation, so the installation cost is higher.
