锚地与海缆是用于保障海上交通、通讯的重要海上设施,锚地中船舶抛锚、拖锚等行为可能会对周边海缆造成损坏。文章从船舶、环境、人员和海缆等不同角度,科学分析海缆损坏的因素;从损坏诱因出发,运用锚泊船内外部因素模拟出走锚漂移过程,结合拖锚啮入深度、抛锚贯入深度以及船员应急状况下的决策时机模型,构建出海缆损坏风险模型,并以温州港鹿西岛引航检疫锚地与周边海缆开展实例研究。研究表明,海缆损坏风险的取决于船舶与海缆距离、船型及船舶尺度等。模型从多角度对海缆损坏展开了研究,为锚地与海缆的相互影响提供了定量的分析方法,为水域安全运行提供了有力支持。
Anchorage and submarine cables are crucial maritime facilities safeguarding sea traffic and communication. Ship anchoring and dragging in anchorage areas can potentially damage nearby submarine cables. This article scientifically analyzes factors contributing to submarine cable damage from perspectives including vessels, environment, personnel, and cables. Starting from the causes of damage, simulations of drifting due to anchor dragging are conducted, considering factors such as anchor penetration depth, vessel type, and crew decision-making during emergencies. A risk model for submarine cable damage is developed, with a case study conducted in the Lu Xi Island pilot quarantine anchorage at Wenzhou Port and its surrounding submarine cables. The study reveals that the risk of cable damage depends on vessel-cable distance, vessel type, and vessel scale. The model provides a quantitative analysis of submarine cable damage from multiple angles, offering valuable support for safe maritime operations.
