Bayu Undan Topsides

Facts & Figures

FROM: Hyundai Heavy Industries, Ulsan, South Korea
TO: Bayu Undan gas recycle field, Timor Sea
CLIENT: Clough Aker Joint Venture (CAJV), Perth, Australia

The transportation part included two consecutive shipments from the HHI yard in Ulsan to the Timor Sea. First the CUQ topside was loaded by using a skid-on loading operation over Blue Marlin’s port side. Subsequently the unit was transported to the Bayu Undan Field. The second shipment, the DPP topside, was loaded and transported in exactly the same way. The installation comprised a float-over and mating operation using the vessel’s ballast system and different types of shock absorbers between the stabbing cones and jacket legs and between the topside and its supporting DSS (Deck Support Structure) units.
