Caterpillar Marine Power Systems have announced the shipment of the first Mak M 46 DF dual fuel marine engine.

The M 46 DF is Caterpillar’s first marine dual fuel solution. It 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.

It will immediately go into the ship’s hull when it arrives.

Caterpillar Marine Power Systems senior product definition engineer Detlef Kirste said the M 46 DF will give AIDA superior performance and operational flexibility without forgoing power or reliability.

The engine switches from gas to diesel mode during operation and it offers flexibility to operate vessels reliably in all geographical areas whether the fuel is gas, marine diesel oil or heavy fuel oil.

It has economical fuel consumption in gas mode and complies to IMO III and EPA Tier 4 regulations. The engine has been designed to allow retrofitting of current M 43 C engines.

With a bore of 460 millimetres and stroke of 610, the engine was designed for electric drive propulsion systems and mechanical propulsion systems.

It is designed for unlimited operation on LNG, marine diesel oil and heavy fuel oil and still reaches industry-leading efficiency in gas mode.

Caterpillar offers support for installation and application, system integration support, as well as customer and crew training. The M 46 DF is distributed and sold through Caterpillar’s MaK dealer network.
