MAN Diesel SE has Celebrates Delivery Milestone

Among total orders for over 140 of its type 58/64 heavy fuel engine sold to China in the past 6 years, the Augsburg works of MAN Diesel recently delivered the 100th example of its seven cylinder, inline configuration type 7L58/64 type engine to a Chinese shipyard.

The special success of the seven cylinder version of the 58/64 is based on its popularity as the main engine in the type CV 1100 TEU container feeder ship. This vessel type is built at a number of shipyards in China, including the Jinling, Jiandong and Qingshan facilities of the CSC Group. As its name indicates, the CV 1100 TEU feeder has container carrying capacity of 1100 twenty foot equivalent units.

MAN Diesel reports that this vessel type was first built in Europe and the design transferred to China in the early 2000’s. The first delivery of a 7L 58/64 for a CV 1100 TEU feeder to a Chinese yard took place in 2001. Orders for CV 1100 TEU come predominantly from German shipowners, MAN Diesel reports. In a typical vessel the propulsion system consists of a 7L56/64 engine rated 9800 kW at 428 r/min, driving a 5.4 metre diameter MAN Diesel Alpha controllable pitch propeller. In most vessels the rated speed of the engine is reduced to 131 r/min. at the propeller by means of a reduction gear from MAN Diesel’s sister company Renk AG, based in Rheine; Germany. To achieve economic onboard electrical power, the gear also features a power-take-off for a shaft generator on its rear side.

In addition to the seven cylinder 7L 58/64 engines, MAN Diesel reports that it has also sold a considerable number of the 11,200 kW rated eight cylinder version of the series, the 8L 58/64. These engines are, again, predominantly used in container feeders - in this case the feeders have a carrying capacity of 1200 to 1500 TEU and features a similar propulsion layout. In fact, counting all the 58/64 engines it has sold to China, MAN Diesel fully expects to pass the 150 engine mark in the foreseeable future. Since business with China first began in 1995, MAN Diesel has produced medium-speed, four-stroke marine propulsion engines with a total output of 2,600,000 kW for Chinese customers at its Augsburg plant. This boom translates as 3.5 years of full production capacity for the works, MAN Diesel states.
