[0057] Take the Zhongtian-Meizhou 110kV line project of the State Grid Power Transmission and Transformation Design Competition as an example. The average water temperature is 20°C. According to the survey, the maximum water depth in the sea area is 14.7m. The strata in this section are mainly Holocene marine deposits and flood Accumulative sedimentary layer, residual layer and fully weathered granite layer.
[0058] Calculate and analyze according to the geology of the seabed section map obtained from exploration. The submarine cable routing area passes through the Wenjia branch channel. After consultation with the channel manager (Fujian Province Meizhou Bay Port Administration), it is recommended to lay submarine cables at least in accordance with the water depth requirements of 3000-ton ships. According to research and relevant statistical data, 3000 Tonnage ships use Hall anchors, and the anchor weight is about 2.5t.
