Magnolia is an offshore oil drilling and production Extended Tension Leg Platform in the Gulf of Mexico. It was the world's deepest ETLP, reaching 1432m (4,698feet), beating the Marco Polo TLP by 120m (390feet).[1] In March 2018, Big Foot ETLP took over this claim in 1580m (5,180feet).
The hull consists of four circular columns connected at the bottom by rectangular pontoons. At the base of each column, a pontoon extends outward to support two tethers, which are connected to pile foundations on the seabed. The design capacity is an estimated daily production of 50000oilbbl of oil and 150000000cuft of natural gas.[2]
The Magnolia field is located approximately 180miles south of Cameron, Louisiana, in Garden Banks blocks 783 and 784 in the Gulf of Mexico. It is located along the southern edge of the Titan Mini-Basin where multiple deep-water reservoir sands encounter a series of down-to-the-basin and antithetic faults adjacent to salt.[3]
