The launching ceremony of the oceanographic research ship "Zhang Jian" was held in Wenling, Zhejiang Province, on March 24. It is the first ship of its kind in China to be built by a privately-owned enterprise, with a total investment of 200 million yuan (about US$30.72 million). As planned, the ship will take its trial voyage at the end of May before being handed over in June and undertaking its first scientific research mission in the Mariana Trench in December. The ship is 97 meters in length and 17.8 meters in width, with a displacement of about 4,800 tons and a sailing speed of 12 knots. The cruising radius of the ship is 15,000 nautical miles, with a carrying capacity of 60 people and a bearing capacity of 60 days. The ship can carry many additional scientific research instruments, including manned and unmanned submersibles designed to reach a depth of 11,000 meters.
