Caterpillar Marine Power Systems shipped the first MaK M 46 DF dual fuel marine engine. The M 46 DF, Caterpillar’s first marine dual fuel solution, will power a newbuild ordered by Germany’s AIDA cruises. Three 12 M 43 C marine engines will also power the cruise liner. The engine left the MaK Rostock, Germany facility en route to Mitsubishi Heavy Industries in Japan. Upon arrival, it will immediately be placed in the ship’s hull.

Able to alternate from gas to diesel mode during operation, the M 46 DF offers the flexibility to operate vessels reliably in all geographical areas, whether the fuel in use is natural gas, marine diesel oil (MDO) or heavy fuel oil (HFO). In gas mode, the M 46 DF features industry-leading fuel consumption and will comply with IMO III as well as EPA Tier 4 regulations. The engine has been designed to allow retrofitting of current M 43 C engines.
With a bore of 460 millimeters and stroke of 610 mm, the engine was designed for electric drive propulsion systems as well as mechanical propulsion systems. Although designed for unlimited operation on LNG, marine diesel oil and heavy fuel oil, the M 46 DF will reach industry-leading efficiency in gas mode.
