Wärtsilä is to supply a reliquefaction system for a retrofit project on an LNG carrier vessel, the ‘Energos Grand’ owned by Connecticut, USA based operator Energos Infrastructure, which has been converted to operate as a floating storage unit (FSU).

The FSU is being chartered by New Fortress Energy. The Wärtsilä 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.

Tim Twomey, SVP Fleet Technical, Energos Infrastructure said: “Wärtsilä’s experience and expertise in LNG reliquefaction and gas handling are well known and we had no hesitation in selecting their equipment and services for this project. We are therefore glad to again team up with Wärtsilä as a critical partner for our conversion projects, and view their reliability and robust technology as an important factor to proceed with this project.”

Pål Steinnes, Head of Sales and Business Development Midstream, Wärtsilä Gas Solutions 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.”

The Wärtsilä equipment is scheduled for delivery during the second half of 2024.
