Wärtsilä Corp. says Danish tanker operator Terntank Rederi A/S (Terntank) will be the first ship owner to use its new 2-stroke, low pressure, liquefied natural gas (LNG)-capable dual-fuel engines.

Martin Wernli, Vice President, 2-stroke, Wärtsilä Ship Power, said it was "an historic landmark in the process towards general acceptance of LNG as a marine fuel and a cleaner future for shipping."

Two new 15,000 deadweight-tonne eco-tankers will use Wärtsilä RT-flex50DF engines, which are IMO Tier III compliant in gas mode and offer environmental and economic efficiencies compared with other 2-stroke engines.

The engines will provide 15 to 20 percent capital expenditure savings compared with other 2-stroke gas engines because they eliminate the need for an exhaust gas cleaning system and reduce the cost of LNG handling.

Terntank chose the egines as part of its "Into the future - Baltic SO2lution" project to improve sustainability and energy efficiency of shipping in the Baltic Sea region.

"These newbuild tankers will be among the world's most environmentally sustainable ships, and we are very proud of this," said Tryggve Möller, a Terntank board member.

"Conventional product tankers of this size have an average bunker consumption of 22 to 25 tons a day.

"With these newbuildings we expect daily bunker consumption of just 14 tons."

Wärtsilä has called the newly introduced engines "game-changing" because of their environmental and economic benefits.
