Introduction Protection of submarine power cables is an important part of offshore wind farms construction. The largest insurance claims in offshore wind power are due to cable damages. As the cable routing is long, it will pass through different regions. Therefore, the protection schemes in each area are different.
Method In this paper, the basic situation of submarine power cable protection is briefly introduced, and then the submarine cable landing scheme is described in detail. Then, the protection scheme of the submarine power cable over other cables or pipes and besides cable tube is described. Finally, the protection schemes of submarine power cable in offshore wind farm is summarized.
Result For the landing section of submarine cables, casing protection, cable trenches and horizontal directional drilling schemes are mostly used; for the cross-section of submarine cables, cushion block solution is adopted at the crossover point; for the submarine cable near the foundation, J-tube with a bend restrictor is mainly used.
Conclusion No matter which method is adopted, the protection of submarine cables in offshore wind farms should be highly valued to ensure the safety of submarine cables during operation.
