Wärtsilä has agreed to supply specialist reliquefaction equipment for a retrofit project converting a Liquiefied Natural Gas (LNG) carrier vessel to a floating storage unit for Energos Infrastructure.
The manufacturing and technology company will supply a reliquefaction system for the vessel, named the Energos Grand, which limits waste by allowing boil-off-gas (BOG) from the LNG to be reliquefied and returned to the cargo tanks.
Tim Twomey, senior vice-president of fleet technical for Energos, said his company had “no hesitation” partnering with Wärtsilä on the project due to the company’s experience and expertise in this field.
Twomey said: “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.”
LNG fuels have become increasingly popular in the shipping industry as a transitional fuel thanks to their potential to reduce greenhouse gas emissions by 20% as well as almost eliminate all fine particle and sulphur emissions, reduced by 99%.
Wärtsilä’s equipment was booked in March 2023 and is expected to be delivered during the first half of 2024 to the 145,880 m3 capacity vessel, which is being chartered by New Fortress Energy.
