GUANGZHOU, Dec. 30 (Xinhua) -- China delivered a new support ship for saturation diving in the southern Chinese city of Guangzhou Monday, according to its developer.

Developed by the China State Shipbuilding Corporation Limited and a ship design company in Shanghai, the ship named Hailong is China's most advanced supporting ship for saturation diving.

The ship is 124 meters long, 24 meters wide and has a cruising speed of 14.5 knots. It has a deck area of 900 square meters and can hold 120 people. The ship adopts the integrated design of the diving system and the main hull, carrying a world-class saturation diving system.

The saturation diving system allows divers to dive hundreds of meters in deep-sea and work for a long time. It is widely used in the fields of marine resources development, emergency rescue and salvage as well as scientific research.

The ship is equipped with a DP3 dynamic positioning system, allowing it to conduct positioning work at a wind speed of 25 knots and a seawater flow rate of 1.5 knots. It carries two remotely operated underwater vehicles (ROV) working at a depth of 3,000 meters undersea, helping ensure the safety of underwater operations.

Besides supporting saturation diving, the ship can carry out multiple tasks including deepwater surveys, seabed construction and dynamic positioning.
