Risk Focus: Gas Carriers

Gas carriers now sit at the centre of global energy security, supporting the transport of LNG, LPG and an expanding range of emerging gaseous cargoes. Once a highly specialised sector, gas shipping has evolved into a diverse and technologically complex ecosystem shaped by shifting trade patterns, new cargo chemistries, evolving vessel designs and increasing regulatory and digital pressures.

In this Risk Focus, we examine how the gas carrier sector has developed over the past decade and what this means in practice for owners, charterers, operators and traders. We explore how advances in containment systems, propulsion technologies, terminal infrastructure and automation have strengthened safety and efficiency, while also introducing new operational, commercial and liability challenges.

Drawing on our technical, operational and claims experience across the LNG and LPG trades, this guide connects engineering reality with contractual exposure. It highlights where risk most commonly accumulates on modern gas carriers and how disciplined operations, accurate documentation and informed contract management remain essential as the sector adapts towards 2030 and beyond.

Key topics and questions explored in this guide

• How has the global gas trade evolved, and why do gas carriers now play a strategic role in energy security?
   
• What hazards do different gaseous cargoes present, and how are those risks controlled on board?
   
• How do vessel designs differ across gas trades, and why does this matter operationally and commercially?
   
• How are propulsion systems, reliquefaction and boil‑off management evolving?
   
• What risks arise at the ship‑shore interface and during cargo operations?
   
• What new vulnerabilities are introduced by digitalisation and automation?
   
• How do cargo characteristics translate into charterparty and claims exposure?
   
• What does recent claims experience reveal about where risk accumulates?
   
• How is the gas carrier sector expected to evolve towards 2030 and beyond?
