China's new submarine cable engineering ship Zhou Shipung delivered on the 7th

A new type of submarine cable engineering ship, Zhoudian No. 7, jointly developed by Zhejiang Zhoushan Power Bureau and the Naval Communications Research Institute, was commissioned on January 6, 2012. This is a domestically-designed and manufactured submarine cable mobile operation platform with dynamic positioning function that can meet the requirements of comprehensive construction such as laying of submarine cables, full salvage, and embedding.

"Zhoudian 7" has a full-load displacement of about 3,000 tons and a wind-resistant wave capacity of 8 grades. It can lay the deepest submarine cable to under 3.5 meters under the seabed in more than 100 meters of water. The ship can undertake the deployment, maintenance, replacement and burying of various types of submarine cables between China's territorial sea and islands.

Submarine cable laying, salvage, and detection technologies have long been a worldwide scientific research problem. The research and development of "Zhoudian 7" is not only an important part of the construction of the marine transmission experiment base, but also provides strong support for the development of marine transmission technology research work and will inject new vitality into the construction of the Zhoushan Islands New Area power grid.
