Wärtsilä will supply compact reliquefaction plants for three LNG carrier newbuilds ordered from South Korea’s Hyundai Samho Heavy Industries (HSHI) by Norway’s Knutsen OAS Shipping
Set for delivery in Q3 2021, these are Wärtsilä Compact Reliq systems based on reversed nitrogen Brayton cycle refrigeration technology. The technology keeps the cargo cool under all operating conditions, reliquefying the boil-off gas to be used as fuel for the ship’s engines, with the excess returned to tanks as LNG cargo.
“We have had good experience with Wärtsilä’s reversed nitrogen Brayton cycle reliquefaction plants in the past, and the Compact Reliq is an exciting addition to their portfolio. It makes onboard reliquefaction viable for all sizes of carriers and is clearly the right choice for our new ships,” said Knutsen OAS Shipping newbuilding director Jarle Østenstad.
The Knutsen newbuildings ordered in 2020 from HSHI were the first to use Compact Reliq technology. Those ships will begin commercial operations in late 2022.
