Mitsubishi Heavy Industries, Ltd. (MHI) has completed the trailing suction hopper dredger/oil recovery vessel, Seiryu Maru, for the Ministry of Land, Infrastructure and Transport (MLIT) at the Kobe Shipyard. The
ships from the class are really amazing made for special purpoese. This Seiryu Maru was built as a replacement ship for the old Seiryu Maru that had been built in 1978. Functions coping with disasters have been added to the new vessel besides those of dredging/oil recovery. Usually, the vessel is engaged in dredging fairway and anchorage areas in Nagoya port. If an oil spill accident occurs, the ship mobilizes to the oil spill site, and engages in oil collection. In a disaster such as an earthquake, etc., the vessel can be used as a base to cope with disasters. For this purpose, an information communications system, conference room, and helicopter deck are provided. As a dredger, the Seiryu Maru is the aft center trailing suction type with a drag head of 7.2m wide, which achieves the level dredging. In addition, the recycling system, which returns the dredged thin muddy water in the hopper to the drag head, was adopted to improve the dredging efficiency. For dredged material handling, a land discharging system has also been developed, which avoids marine pollution. The oil spill recovery system is a new development. The oil recovery system is provided with two different types of oil recovery system to cope with low to high viscosity oil types, and it is possible to operate in significant 2.5m height waves. For collection of spilled oil, a jet water system is employed instead of the conventional oil boom type. The Seiryu Maru is also fully automated. The integrated system is applied to dredging, land discharging, ship maneuvering, oil recovery, and engine room operation. The control network system is installed for managing data, image, disaster, and remote diagnostic controls. really interesting design of some
cruise ships, cargo ships and
yachts can be see on such vessels.
