【摘要】：随着社会发展，能源的开发和使用获得人们越来越多的关注，尤其是可再生能源逐渐走入大众的视野。波浪能作为一种清洁无污染可再生能源取之不尽用之不竭，并发展迅猛，同时波浪能可再生利用技术对于顺应我国发展可再生能源的战略、实现中长期节能减排目标以及海洋开发等方面有重要意义。近年来波浪能利用装置发展多种多样，但在目前波浪能装置的研发过程中，一套波浪能获取装置需要建造一个大的基础支撑结构，由于海洋环境的严酷和不稳定性，使这些支撑结构往往需要大规模的海上施工，在施工过程中同样需要利用大型海洋工程设备，这样往往造成整个波浪能项目投资一半甚至一大半被用掉，从而最终导致了海洋能开发的成本变得非常巨大。本文基于上述原因，提出了几种与海洋现有海洋石油开采平台相结合的波浪能开发利用装置，该装置主要采用第三代振荡浮子式波能采集利用装置与平台导管架支撑相结合，不仅解决了波浪能采集装置支撑问题，同时节省大量投资，经济成本大大降低。通过多种不同结合方案对比参选，对于不同形式或用途的导管架进行结合，既可以起到废弃结构物的再利用，又可为依然进行生产的平台提供源源不断的清洁可再生能源。文章主要运用ansys建模及AQWA水动力软件进行模拟分析，研究包括以下几点：(1)多种波浪能装置形式下于导管架结合方案优劣性对比分析；(2)导管架与振荡浮子式波能发电装置结合形态下波能吸收装置运动形态分析，主要通过AQWA对采集装置运动位移变化，速度及加速度进行数据分析，结果表明导管架平台系统本身对波能采集装置影响较小，波能采集系统在与平台结合方案下的运动效果较为理想，符合波能发电装置本身工作需求；(3)波能采集装置与平台结构结合对平台本身稳定性影响分析，通过AQWA中反馈波能采集装置受力及运动状态，运用ansys对导管架进行结构稳定性分析，，结果表明波能采集装置在一定范围尺寸内对平台本身结构稳定性影响较小，在较大尺寸下会产生一定影响，但对结构本身不会造成破坏性。
[Abstract]:With the development of society, more and more attention has been paid to the development and use of energy, especially renewable energy.Wave energy as a clean and non-polluting renewable energy is inexhaustible and develops rapidly. At the same time, wave energy renewable utilization technology conforms to the strategy of developing renewable energy in China.Achieving long-term energy-saving and emission reduction targets and ocean development is of great significance.In recent years, wave energy devices have been developed in a variety of ways. However, in the current research and development of wave energy devices, a set of wave energy acquisition devices need to build a large foundation support structure, due to the harsh and unstable marine environment.These support structures often require large-scale offshore construction, and the use of large marine engineering equipment is also required in the construction process, which often results in the use of half or even more of the entire wave energy project investment.This eventually led to the cost of ocean energy development becoming very large.Based on the above reasons, this paper puts forward several kinds of wave energy development and utilization devices combined with the existing offshore oil exploitation platform. The device mainly uses the third generation oscillating float type wave energy acquisition and utilization device and platform jacket support.It not only solves the support problem of wave energy acquisition device, but also saves a large amount of investment and greatly reduces the economic cost.Through the comparison of different combination schemes to combine the jacket with different forms or uses, it can not only reuse the waste structures, but also provide a continuous stream of clean and renewable energy for the platform that is still in production.This paper mainly uses ansys modeling and AQWA hydrodynamic software to simulate and analyze.The research includes the following points: 1) comparing and analyzing the merits and demerits of the jacket combination scheme under various wave energy devices) the motion pattern analysis of the wave energy absorber device under the combination of the jacket and the oscillating float type wave energy generating device.The data of motion displacement, velocity and acceleration of the acquisition device are analyzed by AQWA. The results show that the jacket platform system has little influence on the wave energy acquisition device.The motion effect of the wave energy acquisition system under the scheme of combining with the platform is relatively ideal. The effect of the combination of the wave energy acquisition device and the platform structure on the stability of the platform is analyzed.The structural stability of the jacket is analyzed by using ansys through the force and motion state of the feedback wave energy acquisition device in AQWA. The results show that the wave energy acquisition device has little influence on the structural stability of the platform in a certain range.It will have a certain effect on the larger size, but it will not cause damage to the structure itself.
