【#Tech24H】Recently, China's first rocket net recovery vessel, "Linghangzhe," made its inaugural docking at Sanya Nanshan Port. The "Linghangzhe" is China's first ship designed for rocket net recovery, measuring 144 meters in length, 50 meters in width, with a draft of 5.5 meters and a full-load displacement of 25,000 tons. It is equipped with DP2 dynamic positioning capability. As a recovery vessel, the "Linghangzhe" has higher requirements for roll, pitch, and yaw performance, with its dynamic positioning system needing to meet precision specifications under various wave directions. The hull structural design also faces technical challenges such as highly concentrated load distribution.
