Wärtsilä to supply engines for seven new Arctic Shuttle Tankers

20 January 2021

Wärtsilä announced it will supply the main and harbor engines for a series of seven new Arctic Shuttle Tanker vessels being built at the Samsung Heavy Industries (SHI) yard in South Korea. The order, placed with Wärtsilä in December 2021, is valued at more than €100 million.

The vessels will each feature six Wärtsilä 31DF dual-fuel main engines operating primarily on liquefied natural gas (LNG) fuel, and two Wärtsilä 20 harbor engines. All will be fitted with selective catalytic reduction (SCR) systems for NOx emission control. Wärtsilä is the sole supplier for this large scope package, including main and auxiliary power as well as emissions abatement.

“The Wärtsilä 31 series of engines has set a benchmark in efficiency for the industry,” said Östen Lindell, Sales Director East Asia & China, Wärtsilä Marine Power. “The diesel version has been recognized by Guinness World Records as the world’s most efficient 4-stroke diesel engine, and all versions of the Wärtsilä 31 engine series have the same high focus on efficiency. This is important for vessels such as these operating in Arctic waters, where operational reliability and environmental sustainability are of critical importance.”

The 120,000 DWT vessels are Arc 7 classified and have icebreaking capability. The Wärtsilä engines are designed to operate at temperatures as low as -45°C. SHI has considerable experience in building ships of this type.

The Wärtsilä equipment is scheduled for delivery to the yard commencing in Q4 2022, and the ships are expected to be ready for commissioning between 2024 and 2027.
