Table 1

Comparison of independent type tanks for LNG-fueled ships.

Tank type	Independent cylindrical	Independent prismatic	MOSS type (independent spherical)
IMO tank type	Type C	Type A	Type B
Schematic structure
Secondary barrier	No requirements	Complete	Partial
Characteristic	Pressurized at ambient or lower temperature	Fully refrigerated at atmospheric pressure	Fully refrigerated at atmospheric pressure
Notes	For small vessels less than approx. 20,000 m^3 capacity	For large vessels	For LNG carriers
