MHI Shimonoseki Shipyard to build research vessel

MHI research vesselOCTOBER 1, 2013 — Japan's Mitsubishi Heavy Industries, Ltd. (MHI) has received an order for construction of a wide-area seabed research vessel from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

Its capabilities will include mineral and ore deposit origin and formation condition research and will also enable contributions to disaster prevention research.

Construction is to get under way at MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture within the current fiscal year, with completion scheduled for March 2016.

The ship will be approximately 100 m in length and 19 m in width, with gross tonnage near 5,500 tons.

To efficiently conduct survey research of ocean floor resources, it will be capable of operating such state-of-the-art equipment as a seismic research system for investigating crustal structure, large piston corers and a seafloor-mounted excavator for collecting seabed samples, a remotely operated vehicle (ROV) and an autonomous underwater vehicle (AUV).

Sea speed will be approximately 12 knots, with a crew capacity of 65.

The vessel will also be outfitted with a marine research laboratory enabling swift analysis of collected samples without any time-lag.

Selection of the shipbuilder was made through an open proposal submission process. MHI was initially included among the pool of candidates in recognition of its technological strengths.

In recent years MHI has constructed a number of cutting-edge research vessels. Among them are the Shinsei Maru, delivered to JAMSTEC for studying the marine ecosystem off the coast of Tohoku in northeast Honshu, and the Hakurei, delivered to Japan Oil, Gas and Metals National Corporation (JOGMEC) to study marine resources.
