FLÜSSIGERDGASTRÄGER MIT SPHÄRISCHEN TANKS UND DOPPELBODEN

摘要

A carrier vessel 2 is arranged with at least one spherical cargo tank 6 for transporting LNG. The carrier has an outer bottom 4 and an inner bottom 3 defining a double bottom, while a number of hollows 5 are provided in the inner bottom and spaced in the longitudinal direction of the carrier. Each hollow is designed to accommodate a portion of each cargo tank. The distance from the inner bottom to the neutral axis (NA) of the carrier constitutes about 25% of the distance from the outer bottom to the main deck 23. The space 16, 17 and 18 between the inner and outer bottoms is a closed space and constitutes voids and ballast tanks.
