Houlder is awarded the detailed design and engineering for the retrofit of an Air Liquide Boil-Off Gas (BOG)
Houlder Ltd has been awarded the detailed design and engineering for the retrofit of an Air Liquide Boil-Off Gas (BOG) reliquefaction plant by Avenir LNG. This work follows the successful completion of basic design and engineering by Houlder in Q1 of 2022.
The new subcooler plant shall be fitted onboard their new build bunker vessel ‘Avenir Achievement’, with Installation planned for the end of 2022 ahead of the vessel's first long-term charter with Shell in Q1 of 2023.
The new TBF700 plant has capacity to reliquefy up to 1Te of BOG per hour. The system shall allow Avenir Achievement to maintain its LNG cargo at a low temperature, avoiding ‘LNG ageing’ and maintaining cargo characteristics when bunkering. The system shall prevent losses during idle periods, permitting reliquefication of received cargo vapour after bunkering operations, further reducing wasted cargo and greenhouse gas emissions.
Houlder have previously completed detailed design and engineering for the installation of five other Air Liquide reliquefaction plants onto LNG carriers.
