The technology group Wartsila will supply the main and harbour engines for a series of seven new Arctic Shuttle Tanker vessels being built at the Samsung Heavy Industries yard in South Korea. The order, which is valued at more than EUR 100 million, was placed with Wartsila in December 2021. The vessels will each feature six highly efficient Wartsila 31DF dual-fuel main engines operating primarily on liquefied natural gas fuel, and two Wartsila 20 harbour engines. All will be fitted with selective catalytic reduction systems for emissions abatement. By selecting Wärtsilä as the sole supplier for this large scope package, system compatibility and procurement interfacing is simplified, which in turn eases installation work and reduces project risk?The 120,000 DWT vessels are Arc 7 classified and have icebreaking capability. The Wärtsilä engines are designed to operate reliably at temperatures as low as minus 45 degrees 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.
