LNG barge / coastal LNG transport vessel

Class overview

LNG barges move small parcels along rivers, canals and sheltered coasts, often to industrial users or satellite storage that no seagoing vessel can reach. Many are non-propelled and pushed or towed. Deck-mounted cylindrical Type C tanks keep the hull shallow and simplify construction, at the cost of volumetric efficiency. Arrangements differ greatly between projects.

Operational environment

Sheltered coastal and inland waters, generally moved by tug rather than self-propelled.

Safety and operational considerations

• Towage arrangements and weather limits define the safe operating envelope.
• Inland waterway operation adds bridge, lock and depth constraints to voyage planning.
• Transfer points may be temporary installations with project-specific procedures.
