Yokohama Dockyard & Machinery Works

The Yokohama Dockyard & Machinery Works reaches its history back to 1891 with the establishment of Yokohama Dock Company, Ltd. Originally set up for the purpose of ship repairs, the company later extended its business line to include shipbuilding and machinery production. In 1935, Yokohama Dock Company was merged with Mitsubishi Heavy Industries.
To meet expanding production requirements an additional plant was opened in Honmoku in 1966. In 1982, in conjunction with "Minato Mirai" - a project devised by Yokohama City to promote redevelopment of urban coastal districts - the Works was moved from the site it had occupied since its founding to the Honmoku Plant and Kanazawa Plant.
Today's Yokohama Dockyard & Machinery Works offers technology and products designed to achieve a more comfortable society. With a full understanding of future social needs, the Works remains totally committed to meeting the challenges for new technologies and new fields.

Diesel & Turbine Shop

Our Diesel & Turbine Shop is provided with an FMS (Flexible Manufacturing System) line for processing engine frames and turbine casings and equipped with such test facilities as high-speed spin tester and the diesel engine soundproof testing chambers. Also, the shop is provided with a 230 ton crane capable of loading finished products directly from the shop onto the ship. Outfitted with a fully integrated production line extending from raw material processing through trial runs and up to delivery, this thoroughly modern factory is readily capable of responding to customer demands for high reliability.

Boiler Shop

Our boiler shop is equipped with a CAD / CAM (Computer Aided Design / Computer Aided Manufacturing) bank tube processing line, super heater tube processing line, nozzle neck welding robot, multi-electrode panel welding machine, NC (Numerical Control) multi-spindle drilling machine for drum hole processing and other up-to-date equipment. This results in a truly modern and rationalized factory layout that allows integrated manufacturing from the initial stage of material receiving to the delivery of finished products.

Wind Turbine

Part of the Yokohama Dockyard & Machinery Works is sited on a large, flat terrain with strong but moderate winds.

These conditions are ideal for demonstration tests. In January 2006, the first MWT92/2.4 went into operation. The Works is now operating the MWT95/2.4 with a 95 meter extension of the rotor diameter.
