摘要: 水下软管是悬链锚腿式系泊(CALM)系统的重要组成部分。介绍了CALM系统上的灯笼型水下软管的技术要求、设计工况和分析方法。明确了水下软管设计的关键是合理确定软管分段、浮子布置和水上浮筒偏移。此外,通过算例对水下软管的动态响应和关键部位的疲劳进行了分析,为实际工程设计提供参考。

Abstract: Subsea hose is an important part of catenary anchor leg mooring (CALM) system. The technical requirements, design conditions and analysis methods of subsea hose with Chinese lantern configuration in the CALM system are introduced. It is confirmed that the key of subsea hose design is the reasonable determination of hose section, float arrangement and buoy offset. In addition, the dynamic response of the subsea hose and the fatigue of key parts are analyzed with an example, which provides a reference for practical engineering design.
