The Trusted Partner for LNG Carriers

The liquefied natural gas (LNG) carrier sector is a cornerstone of the LNG supply chain. Operating across major trade routes, LNG carriers transport LNG from export terminals to import and regasification facilities, supporting global energy security and enabling the transition to cleaner-burning fuels. As LNG demand evolves and new terminals and infrastructure come online, LNG carriers remain essential to ensuring safe, flexible and reliable energy delivery worldwide.

Specialized Vessels for a Complex Trade

Liquefied natural gas carriers are highly specialized ships, equipped with advanced containment systems, cargo handling arrangements and propulsion technologies designed to manage LNG at cryogenic temperatures. While they share characteristics with other gas carriers, LNG carriers operate within diverse regulatory frameworks, terminal compatibility constraints and chartering requirements. This complexity demands a dedicated, life cycle focused approach to vessel design, construction and operation. Careful strategic planning is critical to optimizing performance, safety, efficiency and long-term commercial viability.

ABS Expertise Across the Asset Life Cycle

With more than 160 years of maritime experience across vessels and offshore assets, ABS supports LNG carrier projects globally through specialized services spanning the full asset life cycle — from concept design and construction to operation and life extension. Through independent classification, technical advisory and risk-based analysis, ABS helps owners, operators, shipyards, charterers and financiers manage risk, enhance performance and meet evolving regulatory, sustainability and safety objectives.

Comprehensive LNG Carrier Services

This depth of technical knowledge and industry insight positions ABS as a trusted choice in advancing LNG carrier projects worldwide.
