The MAN B&W L48/60 was successfully launched in the mid 1980s as part of the German engine maker’s new generation medium-speed engine program that was developed throughout the 1980s. The L48/60 engines became popular as main engines on medium-sized and small-sized commercial vessels, ferries and offshore tugs and also as auxiliary engines on large commercial vessels. Depending on the engine configuration and number of cylinder, the 48/60 engines can produce power of about 7,200 kW to 21,600 kW at operating speed between 500 to 514 rpm. The 48/60 engine became quite popular among vessel owners, with 245 units sold by 2002, after which it was upgraded to the MAN B&W 48/60B variant for better emissions control and more power. The 48/60 engine has several features that made it popular among vessel owners at the time, such as: a very stiff, monoblock frame casing; underslung crankshaft; individual cylinder jackets, resulting in minimum deformation from gas and mass forces and thermal influences; connecting rod—optimized marine head design with parting line in the upper region of the rod shaft, i.e., extremely low overhauling height; exhaust valves arranged in cages that resulted in simplified maintenance of components. 

Although the MAN B&W 48/60 has been surpassed by other MAN B&W engines in terms of market use, the 48/60 engines still remain in use on many vessels and support for them remains readily available through MAN Licensees and independent engine parts suppliers such as Alang Maritime, especially for major engine components.
