Abstract
A floating platform of vertical axial symmetry which provides processing and/or storage of liquefied hydrocarbon gas. The platform is fixed by mooring or made mobile by added vessel or self-mobilization.
The processing and storage being contained in the floating vessel hull, on the deck, or within a center assembly of the floating vessel. The addition of tanks for storage of LNG and liquefied gases conforming to a non-shipshape hull having nonparallel sides, which maximize the volumetric capacity of the structure, yet minimize the stored fluid product mass dynamic effects on the floating vessel.
