Wärtsilä has won an order to supply six-cylinder Wärtsilä X62DF two-stroke dual-fuel engines to two new large, 180,000m³ LNG carriers.
The carriers are being built by Samsung Heavy Industries (SHI) in Korea on behalf of a collaboration between SK Shipping and Marubeni.
Wärtsilä will provide two six-cylinder Wärtsilä X62DF main engines per vessel, together with the required electricity generator sets powered by Wärtsilä 34DF dual-fuel engines.
SK Shipping COO Kang Seog-Hwan said: "The selection of the Wärtsilä two-stroke, low-pressure, dual-fuel engine technology for these LNG carriers is indicative of the benefits this new technology will bring to the marine sector.
"We are able to meet the crucial requirements of today's shipping business, namely for fuel efficiency, environmental compliance at all engine loads, plus very competitive first time and running costs."
Under this contract, the main engines will be built by a Korean licensee and are expected to be delivered in the first quarter of 2016.
The two vessels, which will be chartered by Total, will be the largest LNG carriers to be able to pass through the Panama Canal after its planned expansion in 2015. The first ship will be delivered in the first quarter of 2017.
The two-stroke dual-fuel engine was developed to offer efficient fuel consumption and low investment costs in November 2013.
Wärtsilä's low-pressure dual-fuel engine provides capital expenditure (CAPEX) reductions of 15% to 20% through a substantially simpler and lower cost LNG fuel gas handling system operating at pressures below 16 bars.
