Tallest structure in the world………..not a building
The Ursa unit is located approximately 130 miles south-east of New Orleans. The water depth averages approximately 4,000ft.
Production from the platform is transported approximately 47 miles via an 18in-diameter oil pipeline and a 20in-diameter natural gas pipeline, to the West Delta 143 platform. Pipeline construction began in 1997. The steel catenary risers at the TLP will be installed by J Ray McDermott, using the Derrick Barge 50. The pipelines will be installed by Allseas Marine Contractors, using the pipelay vessel, Lorelay.
The deck is comprised of six modules, namely the wellbay, quarters, power, drilling and two process modules. These deck modules are arranged in an open-truss frame design, 300ftx300ftx50ft-high, with a total steel weight of approximately 12,500t. The total topside weight is approximately 22,400t, including all equipment and the drilling rig. J Ray McDermott International in Morgan City, Louisiana carried out the module construction, which was begun in July 1996. It incorporates complete separation, dehydration and treatment facilities, designed to process 150,000bbl of oil and condensate per day, plus 400MMcf of gas and 50,000bbl of produced water per day. The quarters module houses up to 110 people.
