The selection of Caterpillar Marine dual fuel engines for a new generation of cruise ships provides further evidence of the power solutions specialist’s lead in the LNG marine propulsion space. The company’s MaK 16 M 46 DF dual fuel engines, along with the full LNG supply and handling system, are to be installed on four new ships, two apiece under construction at Meyer Werft’s Papenburg (Germany) and Turku (Finland) shipyards.
Caterpillar Marine now offers all round LNG propulsion solutions – from shore-side bunkering to on-board storage; from bunker tanks via LNG handling and treatment to the dual fuel engines including automation systems; and ultimately the dual fuel main engines MaK 16 M 46 DF, in close cooperation with LNG and cryogenic specialist Marine Service GmbH.
“From a single source, we provide the complete system for ship operators who wish to capitalise on the benefits of LNG as a marine fuel,” said Ulf Hannemann, Caterpillar Marine cruise and ferry segment manager. “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.”
“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.”
Further, the company is pioneering new techniques which make gas-only operation even more attractive. Research and development at Caterpillar’s Rostock facility has demonstrated the efficient operation of LNG main engines at loads of less than 20% for the first time. Caterpillar demonstrated the capabilities of the MaK M 46 DF engine and started the engine by using LNG from the very beginning, thus avoiding diesel engine specific emissions – another first for the company.
