| 摘 要： | 对海上风机浮托安装的进船过程进行分析,对于H型双体船分别从频域和时域等两个方面进行模拟。在频域模拟过程中,得到不同来浪方向H型驳船的运动RAO;在时域模拟过程中,采用悬链线系泊得到进船过程中波浪作用下船体的缆绳张力。通过计算分析可得:随着缆绳长度的增加,系泊张力逐渐减小;系缆长度相近,系泊张力随之相近。建议在进船过程中需布置长度相近且尽可能长一些的系缆。

| Abstract: | The docking process for float-over installation of the offshore wind turbine is analyzed, and the H-shaped catamaran in both frequency domain and time domain is simulated. The motion RAO of H-shaped barge in different wave directions is obtained in frequency domain simulation. The catenary mooring is used to obtain the line tension of hull under the waves during the docking in time domain simulation. Through calculation and analysis, as the length of the line increases, the mooring tension decreases; as the lengths of the mooring lines are near enough, the mooring tensions are similar. The lengths of mooring lines need to be similar and as long as possible. |
