The 50 meter A-type navigation mark ship (Ningdao Biao 1005) constructed by our company was successfully launched on April 28th. Relevant technical personnel from the Yangtze River Nanjing Navigation Bureau and Zhenjiang Navigation Bureau were commissioned by the Yangtze River Navigation Bureau to participate. After on-site inspection, the ship's line shape was smooth and the posture was stable after launching. The overall construction quality was good, and the progress basically met the expected requirements. The construction period was safe and orderly.

Ningdao Biao 1005, developed under the leadership of the Yangtze River Navigation Bureau and designed by the Yangtze River Shipbuilding Design Institute, has a total length of 51.35m, a width of 9.60m, a design draft of 2.45m, and a design speed of 26km/h. This ship has been optimized based on the standardized Ship Ningdao Standard 1003, adjusting the layout of deck machinery and electromechanical equipment, increasing the operating area of the ship, and strengthening the convenience of electromechanical equipment maintenance, effectively improving the practicality and safety of the ship. The bow of the ship was completed on September 13, 2013 (Ningdao Survey 1001). Currently, this ship is the third vessel constructed by our company. The ship is mainly used for lifting, relocating, throwing, floating frames, lighting fixtures, battery replacement, daily maintenance and repair of digital navigation instruments and meters, as well as coordinating with large navigation mark workboats to throw (set) marks and restore marks. The navigation area is an A-level inland navigation area.

After the ship is launched, it will enter the construction work of pipeline laying, outfitting, interior decoration, and installation and commissioning of main mechanical and electrical equipment. It is expected to be ready for factory trial voyage before the end of September this year. After the completion and operation of Ningdao Biao 1005, it will effectively alleviate the pressure on ships for maintenance of the 12.5-meter deep water channel below Nanjing on the Yangtze River, greatly enhancing the channel maintenance capacity and external public service capacity of the Zhenjiang channel. The follow-up work is being carried out intensively, striving to create high-quality projects in the early stage of ensuring quality, quantity and period.
