en.Wedoany.com Reported - On June 15, a 16,000-ton deep-sea self-propelled cable-laying vessel, designed by the 708th Research Institute of China State Shipbuilding Corporation and invested in by Shanghai Foundation Engineering Group, officially commenced construction at Qinshi Jiamei Energy Technology (Nantong) Co., Ltd., with delivery and operation planned for the second half of 2027.
The vessel has an overall length of 161.8 meters, a beam of 38 meters, and a maximum cable-carrying capacity of 16,000 tons, making it the deep-sea cable-laying equipment with the largest cable-carrying capacity among similar vessels in China.The vessel adopts an all-electric propulsion system, equipped with three azimuth thrusters at the stern and three side thrusters at the bow, providing DP2 dynamic positioning capability and enabling navigation in unlimited waters.
This cable-laying vessel achieves multiple breakthroughs in operational capabilities: it can perform simultaneous laying and burying of submarine cables within a water depth of 150 meters, supports ultra-deepwater dual-channel cable laying at depths of up to 3,000 meters, and can also accommodate multi-task scenarios such as cable repair and optical fiber splicing.The vessel is equipped with inner and outer concentric cable reels and two independent cable laying lines, enabling simultaneous dual-cable laying, and can meet the submarine cable construction needs of offshore wind power or oil and gas projects in domestic waters as well as in Southeast Asia and the Middle East.
Zhang Siqun, Party Secretary and Chairman of Shanghai Foundation Engineering Group, stated at the commencement ceremony that this project is a key move in the group's implementation of the "15th Five-Year Plan" strategy, which will drive the business expansion from single submarine cable laying to the full chain of deep-sea integrated engineering.
