Cylindrical tanks on a shallow hull for rivers and short coastal legs.
- Operational role
- LNG Barge / Coastal LNG Transport Vessel
- Containment system
- Type C Pressure Tanks · Cylindrical Type C Tanks
- Capacity class
- Small-scale (indicative: below approximately 30,000 m³)
- Indicative capacity
- 500–8K m³
- Tank geometry
- Deck-mounted cylindrical Type C tanks, often in modular sets
- Typical application
- Inland waterway and short coastal movements to satellite storage and industrial users
- Hull-space efficiency
- Low by design — tanks sit on deck rather than inside a cargo block
- Infrastructure requirements
- River or coastal berths with modest depth, plus a tug where the barge is non-propelled
- Propulsion options
- Non-propelled or towed
- BOG management
- BOG as fuel
- Advantages
- Reaches inland and shallow locations closed to seagoing vessels — Modular deck tanks simplify construction and future capacity changes — Type C tanks hold cargo through slow transits and long waits without venting
- Limitations
- Very limited parcel size and low transit speed — Restricted to sheltered water and constrained by lock and bridge dimensions — Non-propelled units depend on tug availability
- Typical routes
- Rhine and Danube inland supply · Sheltered coastal runs to satellite storage · Port-internal transfers
