Regional distribution into shallow, coastal, and island markets.
- Operational role
- Small-Scale LNG Carrier
- Containment system
- Type C Pressure Tanks · Cylindrical Type C Tanks · Bi-Lobe Type C Tanks
- Capacity class
- Small-scale (indicative: below approximately 30,000 m³)
- Indicative capacity
- 1K–30K m³
- Tank geometry
- Cylindrical or bi-lobe self-supporting pressure vessels
- Typical application
- Regional distribution to island, coastal and industrial customers
- Hull-space efficiency
- Lower than membrane — cylindrical pressure vessels use hull volume differently
- Infrastructure requirements
- Small jetties and shallow berths; modest shore storage and loading rates
- Propulsion options
- DFDE / TFDE
- BOG management
- BOG as fuel · Reliquefaction
- Advantages
- Shallow draft opens terminals large carriers cannot reach — Type C tanks tolerate pressure build-up during idle periods without venting — No secondary barrier required, simplifying construction in smaller hulls — Cargo parcels sized to regional demand and storage
- Limitations
- Pressure vessels use hull volume less efficiently than membrane systems — Higher cost per cubic metre delivered than ocean-going carriers — Design pressure, capacity and boil-off behaviour vary significantly between vessels
- Typical routes
- Northwest Europe coastal feeder · Caribbean island supply · Southeast Asia archipelago runs
