''Deepwater Horizon'' adalah anjungan pengeboran lepas pantai generasi kelima,<ref name="mms ivan2"/> semi-selam yang dirancang untuk pengeboran sumur [[bawah laut]] untuk eksplorasi dan produksi minyak mentah menggunakan [[pencegah ledakan]] {{Convert|18.75|in|mm|abbr=on}}, {{Convert|15000|psi|abbr=on}}, dan ''marine riser'' berdiameter luar 21 in.<ref name="rig spec2"/>

''Deepwater Horizon'' adalah anjungan semi-selam kedua yang dibangun, meskipun pendahulunya ''[[Deepwater Nautilus]]'', tidak diposisikan secara dinamis.

Sistem permodelanpemodelan semen OptiCem, digunakan oleh [[Halliburton]] pada bulan April 2010, memainkan bagian penting dalam campuran bubur semen dan keputusan penyangganya.
