摘要
合理确定海底电缆安装条件和对相关铺设参数进行评估是海底电缆铺设工程中的重要事项。文章基于悬链线理论和集中质量法,采用简化模型对电缆正常铺设过程进行动态模拟,根据API RP17B中的给出的作业接受标准,提出了相应的海底电缆安装环境条件。进而分析了铺设过程中安装条件的影响因素,总结出波浪、海流、电缆自重和水深对海底电缆正常铺设的影响规律,为海底电缆铺设作业的安全进行提供数据支持。
Determining the installation conditions of submarine cables and evaluating the relevant parameters are important issues in the subject about laying of submarine cables. Based on the catenary theory and the lumped mass method, the paper adopts a simplified model to dynamically simulate the cable’s normal laying process. According to the working acceptance criteria of API RP 17 B, the relative environment conditions of cable installation is given. The influence factors of installation conditions during the working are analyzed. The paper concludes the influencing law of wave,current,cable weight and water depth on the normal laying of the submarine cable, which offers data support for the submarine cable-laying working safety.
