Wartsila Diesel, which is now in the middle of a process to upgrade its total engine porfolio, has designed what it terms the world's largest medium-speed engine.

Current schedules call for the test engine to be started later this year.

Designed in response to market demands for higher outputs and improved efficiency, the new engine — Wartsila 64 — will have a cylinder output of roughly two

MW/cylinder. Meeting this specifi- cation, the in-line version will cover up to 18,000 kW in single engine installation and 36,000 kW in a twin engine installation.

The manufacturer assumes that operations speed — provides a top speed in excess of 30 knots.

Machinery which provides the ves- sel's various hotel services is grouped in the void compartments, along with the fuel tanks and compressed CO2 tanks for engine room fire suppres- sion. This includes a hot water tank, a domestic water pump, a sanitary water pump and a black water mac- erating pump. A reverse osmosis water making system and a diesel- fired furnace for accommodation heating are installed in the starboard engine room.

The computerized navigation sys- tem incorporates an extensive elec- tronic chart database and high level graphics to give constant information regarding the vessel's position, direc- tion and speed. The navigation com- puter system is also capable of send- ing and receiving information, including faxes, via the radio tele- phone modem.

The largest V engines, V16 and V18, have been developed mainly for use in power- plants, but opportunities for very powerful diesel-electric machinery will be explored.

In July 1995, Hitachi Zosen Corporation and government officials of

Kumamoto Prefecture and the Town of Nagasu concluded an agree- ment on the construction of the new Ariake Machinery Works. After developing the detailed design of the project under the guidelines of government authorities, the company began construction on the grounds of its Ariake Works on April 15. This facility is to be a replace- ment for the Sakurajima Works, the company's main machinery facto- ry, located in Konohana Ward, Osaka, Japan. The city of Osaka is carrying out a bay-area redevelopment project in the western coastal area of Konohana Ward.

Since the Ariake Works was inaugurated as a shipyard in 1973, it has been home to advanced shipbuilding technology. Aiming at the 21st century, the company is constructing this new integrated machin- ery works to extend its heavy machinery operation, giving it the capa- bility to produce both marine and land equipment. In particular, the new works is expected to be a world-leading machinery facility that functions as a primary base in the company's international strategy.

Products to be manufactured by the New Ariake Machinery Works include marine diesel engines, industrial machinery such as presses for automobile production and various kinds of plant equipment. The first order has already been received by the new works — the world's largest marine diesel engines, producing 74,640 PS, ordered by

Odense Steel Shipyard Ltd., of Denmark. Full operation of the plant will get under way in October 1 997, six months ahead of schedule.

The single-cycle efficiency of the

W64 will approach 50 percent, but the combi cycle has also been developed, which means that waste heat is used for production of steam to drive a steam turbine.
