MHI Ships 500th Gas Turbine

Posted on July 23, 2009

Mitsubishi Heavy Industries, Ltd. (MHI) recently shipped its 500th gas turbine from its Takasago Machinery Works in Hyogo Prefecture. Since its first gas turbine delivery in 1963, MHI has increased the shipment of gas turbines, while also enhancing their power generation capacity and performance. The 500th unit will be delivered to a large-scale power generation and desalination project - the Ras Laffan C Independent Water and Power Producer (IWPP) Project - currently under way in Ras Laffan Industrial City, Qatar.

The 500th gas turbine is the first unit of eight M701F gas turbines ordered by Ras Girtas Power Company (RGPC), an IWPP formed by companies in Japan, Europe and Qatar. It will be shipped together with the identical 501st unit. The plant to be built in Ras Laffan will be one of the world's largest of its kind, consisting of a natural-gas-fired GTCC power generation facility with a total generation capacity of 2,730 MW and a desalination plant with capacity to produce 63 million gallons of water per day from seawater. The plant is slated to go on-stream in April 2011.

Takasago Machinery Works was established in 1962 as a dedicated turbine manufacturing plant of MHI's Kobe Machinery Works; it became independent in 1964. Manufacture of industrial-use gas turbines was launched in 1963, and its first unit, an MW171 gas turbine with inlet temperature of 732 degrees Celsius (about 1,350 degrees Fahrenheit), was delivered to the Chiba Plant of Asahi Glass Co., Ltd.

Since commencement of its gas turbine business, MHI has focused on technological development targeting higher gas turbine inlet temperatures to enable enhanced gas turbine power generation efficiency. In 1989 the company commercialized the 1,350 degrees C-class M701F and in 1996 developed the 1,500 degrees C-class G-Series. Earlier this year, MHI completed the world's largest and most efficient 1,600 degrees C-class J-Series, and moves are now under way toward its commercialization.
