MAN D&T’s DF engine wins type approval

MAN Diesel & Turbo’s L35/44DF engine has been awarded type approval from leading classification societies at an event in Augsburg, Germany.

The engine showed a perfect performance and is now certified for GenSet and Controllable Pitch Propeller (CPP) operation all over the world,” MAN said in a statement on Wednesday.

Lasting from March 30 to April 2 this has been the longest type approval test MAN has run so far.

Within the shipping industry, all new engines require type approval before installation on board a ship. Class certificates are valid for 5-7 years.

The first L35/44DF’s FAT (Factory Acceptance Test) will take place at MAN Diesel & Turbo’s Frederikshavn, Denmark facility in May, for which the Type Approval Test in Augsburg is a prerequisite, MAN said.

“The 35/44DF showed a spotless overall performance without any unplanned quick changes over from Gas to Diesel during operation or any of the type approval tests,” sums up Günter Heider, Senior Manager at MAN Diesel & Turbo and Head of Test & Validation Four-Stroke Diesel & Gas Engines. “Among the features that were specifically appreciated and praised by the association members were the quick changes over from gas to diesel mode at 100% load, the restriction-free gas load performance at an overload of 110% and the engine’s logic and clear modular design.
