The "Qiaoyuan Hao," a new-generation catamaran specialized for marine engineering surveys, was officially launched on the 22nd. As the vessel with the largest volume, leading comprehensive performance, and intensive technological innovation among similar ships in China, it addresses the shortcomings in China's deep-sea high-end survey equipment and breaks through key technological bottlenecks with multiple original technologies.

The new-generation catamaran specialized marine engineering survey vessel "Qiaoyuan Hao"

The vessel is independently built by China Railway Major Bridge Reconnaissance & Design Institute Co., Ltd. It has an overall length of 76.36 meters, a molded breadth of 23.80 meters, a design displacement of 2,537 tons, and can accommodate 36 people for onboard operations with an endurance of over 60 days. The catamaran hull design significantly reduces roll, pitch, and heave amplitudes.

According to reports, the "Qiaoyuan Hao" features an innovative hydrodynamic design for its catamaran hull, acting like a "wave buffer cushion" for the ship's body, reducing roll amplitude by over 40% and enabling stable operations in sea state 4. It is equipped with a wave-compensated survey drilling rig, effectively solving the industry pain point of "unstable drilling due to ship rocking," achieving centimeter-level drilling accuracy. It adopts an integrated onboard laboratory solution, handling all internal and external survey work in one stop. The vessel is equipped with ample hull energy and life support systems, along with intelligent material management and energy-saving control systems, enabling continuous deep-sea operations without resupply. Its core equipment is 100% domestically produced and independently controllable.

Once operational, the "Qiaoyuan Hao" will primarily serve major projects such as hundred-kilometer-scale mega sea-crossing passages, deep-sea wind power, and island infrastructure construction.
