Rig Fleet – Unparalleled Versatility in Shallow-Water Drilling

Hercules Offshore owns a fleet of 38 jackup drilling rigs capable of operating in water depths from nine to 350 feet.  The majority of our fleet is able to drill as deep as 20,000 feet and the Hercules 350 is able to drill up to 25,000 feet.  The versatility of our rigs enables us to meet the full spectrum of customer requirements.  We operate the U.S. Gulf of Mexico’s only 200 foot workover and completion rig as well as a 2,000-horsepower Big Foot III rig, capable of working in water as shallow as nine feet.  Hercules 170, an independent leg cantilever jackup, is capable of working in water depths from 16 feet to 170 feet.  Hercules 260, a jackup rig with a 250 foot water depth capability, has been upgraded to include increased variable deck load, hook load capacity, the addition of a third mud pump and expanded living quarters, thus enabling the unit to competitively operate internationally.

Barge Fleet – Mobile drilling platforms that are submersible

Hercules Offshore owns a fleet of 13 barge drilling rigs.  The units are mobile drilling platforms that are submersible and are built to work in seven to 20 feet of water. They are towed by tugboats to the drill site with the derrick lying down. The lower hull is then submerged by flooding compartments until it rests on the river or sea floor. The derrick is then raised and drilling operations are conducted with the barge resting on the bottom. Our barge drilling fleet consists of conventional and posted barge rigs. A posted barge is identical to a conventional barge except that the hull and superstructure are separated by 10 to 14 foot columns, which increases the water depth capabilities of the rig. Most of our barge drilling rigs are suitable for deep gas drilling up to 30,000 feet.
