Hitting A Milestone
MAN sells 500th 48/60 medium-speed engine; continuous development of original unit
MAN Diesel & Turbo has announced the 500th sale of its MAN 48/60 medium-speed engine. The milestone was reached with the order of two common-rail variants of the engine by Huta Marine of Jeddah, Saudi Arabia as part of a diesel-electric system to power a self-propelled cutter suction dredger.
Huta Marine is a specialist in marine infrastructure. The dredger will be built in the Netherlands by a shipyard owned by the IHC Merwede Group, a global specialist for dredging, mining and other custom-built vessels.
The 48/60 medium-speed engine, released in 2003, is based on the 48/60 series first launched in 1989. The B variant represented a major redevelopment of the concept characterized by increased output, reduced engine weight/width, and optimized combustion that reduced exhaust emissions and fuel consumption, MAN said.
The 48/60 has been continuously developed ever since, notably including an upgrade to common-rail fuel injection in 2008 and full Tier II compliance in 2011. Recently, the 48/60 underwent a redesign of its cylinder head.
