Advanced Reliquefaction Systems Introduced to Upgrade FSRUs for Greater Sustainability

Wärtsilä Gas Solutions, a division of the technology group Wärtsilä, has been chosen to supply reliquefaction systems for retrofit installation on floating storage regasification units (FSRUs) owned by Excelerate Energy, the largest FSRU operator in the world. This retrofit project aims to enhance the environmental sustainability of Excelerate Energy’s FSRU operations and is expected to be completed by the fourth quarter of 2024. The system to be provided, Wärtsilä Gas Solutions Compact Reliq Double units, utilizes reversed Brayton cycle technology to reliquefy boil-off gas, reducing emissions and conserving cargo simultaneously. Equipped with advanced technology, the system is designed to minimize maintenance and operational costs for the operator.

Excelerate Energy’s COO, David Liner, expressed the company’s commitment to reducing its environmental impact through projects like this. He highlighted the partnership with Wärtsilä Gas Solutions, citing their expertise in reliquefaction systems and advanced technology as key factors in their selection. Walter Reggente, VP of Wärtsilä Gas Solutions, emphasized the company’s leadership in cryogenic gas applications and its ability to support greener shipping operations. The collaboration with Excelerate Energy underscores Wärtsilä’s dedication to delivering quality, commercial value, and environmental benefits to its clients.

Delivery of the Wärtsilä equipment is scheduled to commence in early 2026, marking a significant milestone in the project timeline. This partnership between Wärtsilä Gas Solutions and Excelerate Energy demonstrates a shared commitment to sustainability and innovation in the maritime industry. By leveraging cutting-edge technology and expertise, both companies aim to drive positive environmental change and enhance operational efficiency in FSRU operations.
