Wartsila announces LNG reliquefaction retrofit contract

Technology company Wartsila will supply the reliquefaction system for a retrofit project on an LNG carrier vessel converted to operate as a floating storage unit (FSU), it said on May 15.

The vessel, Energos Grand, is owned by Connecticut-based operator Energos Infrastructure, and is being chartered by New Fortress Energy. The order was booked by Wartsila in March 2023. The equipment is scheduled for delivery during the second half of 2024.

The Wartsila system allows the boil-off-gas (BOG) from the LNG onboard to be reliquefied and returned to the cargo tanks rather than being wasted. The solution contributes to a significant reduction in emissions and creates cost savings, as well as optimising the LNG cargo level, the company said.

“This project shows New Fortress Energy’s and Energos’ commitment to improving the environmental profile of their fleet, and we are happy to once again be shown the trust of these partners in this conversion project. Our robust and reliable Compact Reliq technology is a perfect match for such applications. It combines cost-efficiency with low maintenance to deliver a solid environmental and commercial return,” commented Pal Steinnes, head of sales and business development midstream, Wartsila Gas Solutions.

Wartsila Gas Solutions supplies systems and lifecycle solutions for the gas value chain with main focus areas being handling of gas in seaborne transport, gas to power, liquefaction and biogas solutions.
