L-1114 Jack-Up
Structural Design & Dimensions
The L1114 features a three-leg independent jack-up configuration, supported by a National 400 fixed rack-and-pinion jacking system with 12 pinions per leg, a proven and widely deployed system in the Gulf of Mexico. This arrangement provides reliable elevating capability, precise hull positioning, and structural stability during drilling operations.
Key dimensions include:
• Hull Length: 200 ft
• Breadth: 186 ft
• Depth: 23 ft
• Operating / Transit Draft: 15 ft
• Leg Length: 407 ft
• Leg Spacing: 130 ft x 130 ft
These proportions provide a balanced footprint for seabed penetration while allowing adequate deck space for drilling, storage, and auxiliary systems .
Drilling Package & Mechanical Systems
The drilling package is centered around a Lee C. Moore derrick, rated for 1,240 kips static hook load, enabling the handling of deep well strings and heavy tubulars. The rig is equipped with:
• National Oilwell E-3000 drawworks
• Varco TDS-3H top drive
• National Oilwell C-375 rotary table
• NOV ST-100 iron roughneck
This configuration supports efficient drilling operations while maintaining compatibility with standard Gulf of Mexico well designs .

Well Control & Safety Systems
Well control is provided by a Cameron Type U BOP stack, comprising:
• 13-5/8” × 10,000 psi, three-ram BOP
• Hydril annular preventer (13-5/8” × 5,000 psi)
The rig also includes a Hydril 29-1/2” diverter system, enhancing surface well control capability during shallow gas or top-hole operations. Control systems are managed through a Koomey Model T-20160-3S hydraulic control package
Hoisting, Cranes & Deck Equipment
Material handling is supported by two DNS-60 offshore cranes, each fitted with a 120-ft boom and 15-ft jib, providing a combined static lifting capacity of 130,000 lbs at 30-ft radius. This crane capacity supports supply boat offloading, casing handling, and deck logistics typical of shelf drilling programs .
⸻
Power Generation & Utilities
The rig’s power plant consists of:
• Three (3) EMD 16-645-E8 engines
• Three (3) Oilwell A-1700 mud pumps
Fluid handling and storage capacities include:
• Fuel Oil: 4,587 bbls
• Drill Water: 5,670 bbls
• Liquid Mud (active + reserve): 1,535 bbls
• Bulk Storage: 6,780 cu ft
• Sack Storage: 4,500 sacks
These capacities allow for sustained drilling operations with minimal resupply dependency .
Paragon L1114 Jack-Up Rig – Technical Explanation & Operational Profile
The Paragon L1114 is a Levingston 111-C design self-elevating jack-up drilling rig, purpose-built for offshore shallow-water drilling operations in the U.S. Gulf of Mexico. Constructed in 1982 by Levingston Shipbuilding Company, the rig reflects a robust generation of Gulf-proven jack-ups designed for long service life, high hook loads, and dependable mechanical systems.
Classed by ABS as a Self-Elevating Drilling Unit and operating under the Liberian flag, the L1114 complies with MODU Code requirements applicable to its operational envelope. The rig is engineered to operate in water depths of up to 300 feet and to drill wells to depths of 25,000 feet, positioning it well for conventional shelf drilling, redevelopment wells, and workover campaigns .
