156 M dynamic positioning pile driving barge "has a total length of 130m and a pile frame height of 156m. It can drive the pile foundation with a maximum pile weight of 700t and a diameter of 7m. It is the piling barge with the highest pile frame and the largest pile hoisting capacity in the world at present, and also the first pile driving barge with dynamic positioning system and three world-class performance indicators in China. The height of the ship's pile frame reaches 156m (the highest in the world), and the operating depth exceeds 70m (the deepest in the industry). The piling positioning accuracy can be centimeter level through the coordinated control of dual frequency RTK GPS and Beidou dual mode positioning system. Two global pioneering applications have been realized on the ship: one is the first application of "DP dynamic positioning+anchoring positioning" fusion technology on a large pile driving ship in the world, significantly improving the stability and safety of operation under complex sea conditions; Second, it is the first time to apply the main cylinder closed hydraulic system on the pile driving ship, which can realize energy recovery and green environmental protection while greatly improving the piling efficiency.

VTS-500 valve remote control and liquid level measurement system provided by our company is adopted for "156m dynamic positioning piling barge", which is based on the latest automatic control technology and adopts Ethercat Ring distributed control; All electric valves are used.
