Prismatic Type B tanks with a flat deck and no sloshing limits.
- Operational role
- Conventional Ocean-Going LNG Carrier
- Containment system
- SPB / Self-Supporting Prismatic Type B
- Capacity class
- Conventional (indicative: approximately 125,000–180,000 m³)
- Indicative capacity
- 88K–165K m³
- Tank geometry
- Independent prismatic tanks with internal swash bulkheads
- Typical application
- Floating units and trades requiring unrestricted filling levels
- Hull-space efficiency
- Moderate to high — prismatic shape follows the hull better than spheres
- Infrastructure requirements
- Conventional terminals; flat deck suits offshore topside arrangements
- Propulsion options
- DFDE / TFDE · ME-GI
- BOG management
- BOG as fuel · Reliquefaction
- Advantages
- No sloshing restrictions at any filling level — Flat weather deck simplifies topside arrangement for floating units — Leak-before-failure design with a full secondary drip tray
- Limitations
- Higher steel weight and build cost per cubic metre — Small operating fleet, so benchmarking data is limited
- Typical routes
- Alaska – Japan · Arctic feeder services · Floating production offtake
