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.
