MaK M 46 DF dual fuel engine

Caterpillar Marine’s MaK 16 M 46 DF dual-fuel engines, together with the full Liquefied Natural Gas (LNG) supply and handling system, have been selected for installation on four new ships, two apiece under construction at Meyer Werft’s Papenburg (Germany) and Turku (Finland) shipyards.

Caterpillar’s sales and serviced partner Zeppelin Power Systems, headquartered in Hamburg, is managing the project, including supply, commissioning and service. In close cooperation with LNG and cryogenic specialist Marine Service GmbH, also based in Hamburg, Caterpillar Marine offers LNG propulsion solutions like shore-side bunkering, on-board storage, bunker tanks via LNG handling and treatment and dual-fuel natural gas engines including automation systems.

“We have successfully completed a number of diesel to dual-fuel conversions in the commercial shipping sector and our pipeline of newbuild installations continues to grow,” said Ulf Hannemann, Caterpillar Marine cruise and ferry segment manager.

LNG is a readily available alternative fuel that can reduce emissions and fuel costs. “However, it is in the cruise sector that we see the greatest opportunities,” Hannemann continued. “Clean fuel for cruise vessels is essential in both operational and business strategy terms.”

Caterpillar is pioneering new techniques which make gas-only operation even more attractive. Research and development at the company’s Rostock facility has demonstrated the efficient operation of LNG main engines at loads of less than 20% for the first time.

Caterpillar has demonstrated start of the MaK M 46 DF engine using LNG, avoiding diesel engine emissions. “This development is a key consideration for cruise operators who wish to use LNG, rather than risk smoke from the funnel or soot on deck, whilst starting main engines and maneuvering in port waters,” noted Dr Frank Starke, Managing Director of Caterpillar Motoren.

Carnival Corporation & plc has signed a multi-billion dollar contract to build four next-generation LNG-propelled cruise ships in June, 2015.
