Risk of Anchor Damage to Submarine Cables Near Anchorage

doi:10.16183/j.cnki.jsjtu.2024.068

Abstract

Abstract:

Anchorage and submarine cables are crucial maritime facilities safeguarding sea traffic and communication. However, anchoring and dragging anchors in anchorage areas may pose risks for damaging nearby submarine cables. This paper scientifically analyzes the factors contributing to submarine cable damage from the perspectives of vessels, environment, personnel, and cables. Starting from the causes of damage, the anchoring failure and drifting process is simulated by incorporating the internal and external factors of 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 on the Luxi Dao pilot quarantine anchorage in 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 method for the interaction between anchorage and submarine cable, investigates cable damage from multiple angles, and offers valuable support for safe maritime operations.

Key words: submarine cables, damage probability, anchorages, dragged anchor
