日本科学技术厅海洋科学技术中心最近制造出世界上潜水最深的(6500米)“深海6500”号载人自由航行型潜水调查船,并于1989年1月19日在神户市的三菱重工神户造船所举行了下水仪式。该船将以4月份在和歌山县由良近海进行的潜水25米的性能试验为开端,在日本各地进行反复测试,并于8月份在三陆近海向潜水6500米挑战。人们期待着它能为调查沉睡于日本深海的宝贵矿物资源和阐明地震机制等积极做出贡献。据说世界上最早的正规载人潜水调查船是在1929年由下关的水产事业家西村一松设计建
Japan Science and Technology Agency Marine Science and Technology Center recently created the world’s most submerged (6500 meters) “Deep Sea 6500” manned free-ro-ro diving survey ship, and in January 19, 1989 in Kobe, Mitsubishi Heavy Industries Kobe shipbuilding Held a launching ceremony. The ship will start with a 25-meter diving performance trial at Wakayama Prefecture in April in Wakayama Prefecture, where it will undergo repeated tests throughout Japan and challenge the 6,500-meter diving at Sea Crossing in August. It is expected that it will make a positive contribution to the investigation of precious mineral resources that have fallen asleep in Japan’s deep sea and to clarify the earthquake mechanism. It is said that the world’s earliest regular manned diving survey ship was built in 1929 by the fishermen under the Commissioner of Nishimura pine design
