Shells massive Prelude hull worlds biggest-ever floating vessel and first ocean-based LNG plant

Royal Dutch Shell PLC says it has completed building the hull of the worlds largest floating facility, which has been constructed to process natural gas off the coast of western Australia.

Shell said Tuesday that the 488-meter (1,600 foot) hull of the structure, known as Prelude, was floated out of the dry dock in Geoje, South Korea where it is being built.

The largest ship to date. Even larger than Seawise Giant.
