Introduction
LNG carriers and terminals operate in a fast-evolving industry where downtime and lengthy retrofits can mean lost revenue and missed opportunities. The need for rapid, reliable, and space-saving upgrades has never been greater. Sulzer’s zeroBOG™ technology rises to this challenge with a modular design that enables quick, seamless installation whether for new builds or retrofitting existing vessels and terminals.
The Challenge: Upgrading LNG Infrastructure
Traditional boil-off gas (BOG) recondensation systems are often bulky, heavy, and complex to install. Upgrades or retrofits can disrupt operations for weeks, requiring significant modifications and downtime.
For LNG operators, these challenges result in:
Prolonged outages and lost cargo opportunities
Increased installation and labor costs
Limited flexibility for future expansion or adaptation
The zeroBOG™ Solution: Modular, Compact, and Ready to Go
zeroBOG™ is engineered for maximum installation flexibility and speed:
Modular construction: Delivered as pre-assembled modules, zeroBOG™ can be installed quickly and efficiently, minimizing downtime and operational disruption.
Compact footprint: Up to five times smaller than conventional BOG recondensers, zeroBOG™ fits easily into tight spaces on ships, FSRUs, and terminals.
Seamless integration: Designed for both new builds and retrofits, zeroBOG™ adapts to existing LNG infrastructure with minimal modifications.
Key Benefits for Operators
Reduced installation time: Modular design means faster commissioning and a quicker return to full operations.
Lower project costs: Less labor, fewer modifications, and minimized downtime translate into significant savings.
Operational flexibility: zeroBOG™ can be relocated, scaled, or upgraded as operational needs evolve.
Ease of operation: The self-regulating system and simplified controls make zeroBOG™ easy to operate and maintain, even for crews with limited LNG experience.
Real-World Applications
zeroBOG™ has proven its value in a variety of settings, including:
Offshore platforms like FSRUs and FPSOs
Onshore LNG terminals and refueling stations
LNG-fueled ships and barges
Emerging applications such as Bio-LNG and liquid hydrogen systems
Conclusion
Sulzer’s zeroBOG™ modular design is transforming LNG infrastructure projects.
By enabling fast, flexible installation with minimal disruption, zeroBOG™ empowers operators to stay competitive and future-ready in the dynamic LNG market.
