THE 37,000 METRIC-TON topsides structure was built in a South Korean shipyard before being shipped on the Heerema 851 barge 6,546 km to Western Australia, where it was successfully floated over and set onto the steel gravity structure. The topsides was transported at its full height across the open sea to Australia so that it could float above the legs of the steel gravity substructure (SGS) for installation.
