Chinese Science Ship Dong Fang Hong 3 Launches Today

(Yicai Global) May 30 -- The new generation deep-sea scientific research vessel built by Shanghai-based state-backed Jiangnan Shipyard (Group) was commissioned into service today.

The vessel, whose underwater radiated noise control technology is of the highest international standards, is also one of the world's largest noise-free scientific research ships, local media Shanghai Observer reported.

Customized for the Ocean University of China in Qingdao in China's eastern province, the scientific research ship Dong Fang Hong 3, which can sail for 15,000 nautical miles and carry 110 crew members and researchers, has among the most tonnage and the most ship staff among world scientific research ships. It has 600 square meters of operations deck and a 600-square meter lab area.

The scientific research vessel , whose name means 'the East Is Red' in Chinese, can also probe water, the seabed and atmosphere comprehensively and accurately realize ship-to-land information network connectivity.

It will be one of the marine integrated research ships with the most reliable and genuine scientific research data in the world for some time, the report said.

Founded in 1865, Jiangnan Shipyard has been state owned ever since then.

World's largest silent research vessel built in China

The world's largest silent research vessel built by China was officially put into use on Thursday, which will pave the way for the cultivation of innovative deep-sea talent and ocean science study.

Dong Fang Hong-3 (DFH-3) has obtained the highest underwater radiated noise level certificate from DNV GL (the world's largest classification society in Norway), making it the world's largest silent comprehensive marine research vessel, Wu Gang, the chief designer of the vessel and an expert at the 708th Research Institute of China State Shipbuilding Corporation, told the Dazhong Daily on Thursday.

"When DFH-3 dives under water, fish 20 meters away do not notice it," Wu said.

According to Wu, the vessel's low-noise control indicator has reached the highest level worldwide. The measured weight of the empty ship was reduced by 0.6 percent compared with the initial estimate, and the height of the center of gravity was slightly decreased after the official tilt test of DFH-3 was completed.

"This shows that the project team has mastered the key technology: weight and center-of-gravity control of empty vessels," Wu noted, as a research vessel normally has a relatively small displacement and the weight adjustment space of an empty ship is limited.

DFH-3 has a newly designed air conditioning system that ensures the highest hygiene level for laboratories of research vessels.

The time spent to design and construct a research vessel is four to six years, several times longer than that of commercial ships, and much more workload is involved, such as program demonstration, interface coordination, equipment custom design, and layout optimization adjustments, Chen Ningning, one of the major designers of DFH-3, told Dazhong Daily.

"DFH-3 will build a training platform for improving the quality of talent and conduct a investigation of deep ocean science," an expert from the Ocean University of China, one of the designers of the project, told the Global Times on condition of anonymity.
