Cameron introduces Jaguar class SEDU

Cameron has announced the introduction of its new LETOURNEAU™ Jaguar Class self-elevating mobile offshore drilling unit.

Utilising the LETOURNEAU 1000-Kip Elevating Unit and the LETOURNEAU STORM LOK® leg fixation system, the Jaguar is capable of operating in water depths of up to 400 ft in harsh conditions or 500 ft in moderate waters. The rig is also capable of drilling Ultra-HPHT wells to 40 000 ft with a hook load of 2.5 M pounds and setback capacity of 1700 kips in quads, filling the market gap between the typical premium and ultra-large jack-ups.

The Jaguar class builds upon the success of previous LETOURNEAU designs which account for the largest number of active jack-up rigs in operation today. Unique to LETOURNEAU rig designs, the Jaguar only requires a leg fixation system in severe storm conditions. This design feature allows for approximately a half-day savings each time a rig is moved. Another unique feature of the Jaguar is the design of its spud can and leg well, which allows for pulling individual legs above the waterline; permitting classification society Special Periodic Survey inspection without dry docking, potentially saving weeks of downtime and hundreds of thousands of dollars.

The introduction of the Jaguar class further expands upon Cameron’s Total Rig Package Solutions offering. By providing proven offshore rig designs, drilling and pressure control equipment and services, Cameron is able to provide drilling contractors and shipyards with a complete, fully-integrated solution that reduces integration cost and risk.

Other design features include:

  • Cantilever with 1542 MT (3400 kip) maximum combined drilling load capacity, longitudinal reach of 24.4 m (80 ft) or greater, and transverse skidding movement of ±7.6 m (25 ft) of the rig centerline.
  • Drilling variable deck load including cantilever loads of over 6800 MT (15 000 kips) in 36 m/s (70 knot) winds. Severe storm variable deck load of over 5000 MT (11 000 kips) in 51 m/s (100 knot) winds.
  • Storage to well handling of two 25 000 psi BOP stacks.
  • Includes 11 active/reserve mud pits and two slugging pits, with a 7770 bbl combined capacity. Expanded pit capacity can be easily integrated during construction or may be retrofitted post-delivery.
  • Mud systems large capacity and dedicated piping accommodates simultaneous use of oil, saltwater and fresh water-based muds without cross contamination.
  • Automated tubular handling from pipe rack to downhole, including independent stand making.
