The MAN B&W L58/64 was successfully launched in 1984 as the first engine of the German engine maker’s new generation medium-speed engine program that was developed throughout the 1980s. The L58/64 engines were launched with priorities being high operating economy with reliability, ease of maintenance, component durability and unrestricted heavy fuel comparability. The L58/64 engines became popular as main engines on feeder container vessels and ropax ferries. Featuring a massive bore of 580 mm and a stroke of 640 mm, the original version of the engine could produce power of about 7,280 kW to 10,920 kW at operating speed between 400 to 428 rpm. The newer version had an increased power output of 12.6 MW. Among the main features of the L58/64 engine were a stiff monobloc frame casting with continuous tie-rods from the underslung main bearings to the top edge of the engine frame, and tie-rods from the cylinder head to the frame diaphragm plate. The L58/64 engine was the first engine design that featured a connecting rod with a joint in the upper part of its shaft, resulting in very low overhead space required for piston removal. Several upgrades such as a complete cylinder head and exhaust system redesign and the application of MAN’s TCA turbochargers ensured the L58/64 engines’ growth
