海底电缆检测技术方法选择分析
Analysis on Selection of Submarine Cable Detection Technology

摘要:
海底电力电缆路由、埋深位置和裸露的定期精准检测是保障海缆长治久安及安全运营的根本，海缆精准检测技术方法的选择尤为重要。常规的磁力仪、管线仪探测技术方法是探测海洋管线的主要手段之一，但其结果较为粗略，无法做到精准检测。对比了海缆检测各技术方法的优劣性，提出了以水下机器人为依托，携带摄像头、声呐系统、TSS350近距离检测海缆路由埋深、抛石石坝外观、抛石石坝厚度、海缆裸露悬空及风险点、海缆路由区域障碍物等，辅以多波束、ADCP进行海缆路由区域地形地貌、海流测量，分析海缆埋深、路由等状况变化的原因。同时以海南联网海缆检测应用为例，研究表明：该综合检测方法全面，检测效果好，历次检测检测对比吻合度高，准确掌握了海缆的实际状况。为后期海缆精准检测及运行维护提供了参考依据。 Abstract:There are many submarine pipeline detection technology methods, but due to special requirements of submarine cable detection's high precision. It was rough by using conventional magnetometer and pipeline detection technology, submarine cable was detected by many integrated detection methods base on ROV carrying all kinds of equipment increasingly mature, conventional submarine topography measurement technology as an auxiliary means has been suitable market, meanwhile it has been suitable for complex seabed environment.
