| 我国海域近岸水深较浅，台风频发，对于大型波浪能装置抗极端海况下的锚泊系统设计成为制约波浪能装置产业化发展的技术难点，波浪能发电可为海洋经济提供绿色能源支持，对于海洋战略发展具有重要意义。本论文针对一种改进型MW级波浪能装置抗极端海况下的系统设计问题，通过不同水深下平台的水动力学特性以及设计采用具有超弹性和高强度材料的系泊线材料的锚泊系统并与纯锚链悬链系泊系统进行比较分析，研究平台在极端海况下的系泊载荷与漂移运动特性。研究结果表明：针对浅水锚泊设计，采用具有弹性索材料的系泊系统可以有效降低系泊载荷，同时随着弹性索的使用量的增加可以持续降低系泊载荷峰值，但是随着弹性索使用量达到一定的量弹性索的持续增加对系泊载荷峰值的降低效果将受到限制，此研究将有利于设计浅水抗台锚泊系统和考虑弹性索使用过程中的经济性。 |

| The water depth near the coast of China is relatively shallow and typhoons frequently occur. The design of mooring system for large wave energy installations against extreme sea conditions has become a technical difficulty restricting the industrialization development of wave energy installations. Wave energy power generation can provide green energy support for Marine economy and is of great significance for the development of Marine strategy. Aiming at the system design problem of an improved MW wave energy device against extreme sea conditions, this paper studies the hydrodynamics characteristics of the platform under different water depths, and compares the mooring system design scheme using mooring line material with super-elastic and high-strength materials with that of pure anchor chain catenary mooring system. The mooring load and drift motion characteristics of the platform under extreme sea conditions are studied. The results show that: For shallow water mooring design, the mooring system with elastic cable material can effectively reduce the mooring load, and can continue to reduce the peak value of mooring load with the increase of the use of elastic cable. However, as the use of elastic cable reaches a certain value, the continuous increase of elastic cable will limit the effect of reducing the peak value of mooring load. This study will be beneficial to design the anti-platform mooring system in shallow water and consider the economy of elastic cable in use. |
