Analysis on Anchor Damage of Shore Power Engineering in Bohai Sea

In order to ensure the development and production of offshore oilfields and the safe and stable operation of shore power high-voltage submarine cables in Bohai Sea, the analysis of damage caused by anchors was carried out for 110 ～220 kV shore power high-voltage offshore cables. Through comprehensive risk identification and risk analysis, the main risk factors for submarine cables damaged by anchors were identified. From the perspective of risk, the probability of anchor damage to shore power high-voltage submarine cables and the penetration depth of anchors to submarine cables were quantitatively analyzed and calculated, and the damage level of anchor damage to submarine cable were evaluated, on the basis of which, safety countermeasures and suggestions for anchor damage of high-voltage submarine cable were put forward. This paper has important guiding significance in the safe operation and risk control of high-voltage submarine cables.
