MAIN DECK

ABOUT THE TARzAN CLASSThe TARZAN jack-up is a self-elevating mobile drilling unit, designed for year-round

operation in water depths up to 300 feet in tropical storm regions.

This rig is a result of LeTourneau’s quest to meet the hydrocarbon exploration industry’s

new requirements imposed by complex sub-salt drilling operations, industry innovations,

safety, and environment advantages. This new class of jack-up meets these requirements

with the same high standards of constructability and robustness available in every jack-up

rig with the LeTourneau name. The TARZAN CLASS represents LeTourneau’s dedication to

industry leadership and to building cost efficient, long life cycle jack-ups.

Utilization of the LTI opposed-pinion elevating system and

complementary leg design have resulted in a significant

increase in the environmental criteria and load carrying

capacity under both drilling and storm

conditions. These new features

found on the TARZAN CLASS have

evolved from LeTourneau’s traditional

design philosophy of simplicity of construction,

redundancy, robustness, and ease of operation.

SUpER 116E ABOUT THE SUpER 116EThe Super 116E is an enhanced unit that builds on the

strengths of the original “workhorse” of the industry, the

LeTourneau 116-C, while expanding the capability of its

predecessor, the Super 116. The Super 116E provides

the international offshore drilling industry

with a proven versatile and cost-efficient

tool for exploration and development

ABOUT THE SUpER GORILLADesigned and manufactured by LeTourneau Technologies

Offshore Products, the Super Gorilla lives up to the tough legacy

of the original Gorilla Class. This high-reliability jack-up is known

for coining the term “Harsh-Environment Jack-Up” in 1981. The

Gorilla Class jack-ups are built strong enough to perform almost

anywhere in the world, including some of the roughest waters

known to drillers, the Central North Sea, the African coasts,

the coast of Eastern Asia, both coasts of

North and South America, and the

Bering Sea.

The Super Gorilla features the Slotilever®

that can drill in both the slot and cantilever

modes in a pattern of 102 x 24 feet (31 x 7.3

meters) with drilling loads up to 3,750 kips.

In addition, the first Super Gorillas are dual

classified: American Bureau of Shipping

WAl, Det Norske Veritas 1A1 (N) and built in

accordance with the Mobile Offshore Drilling

Unit Regulations established by the USCG, IMO,

NPD, and HSE (UK) and other regulatory bodies.
