Put the best equipment in the best hands.

Tesco Automated Catwalks (TAC)

Our TAC System transfers tubulars between the pipe rack and the rig floor in the

safest and most controlled manner possible. It can be operated wirelessly with an

explosion-proof remote from the rig floor or manually from the catwalk’s valve back.

Catwalk Control SystemEvery TAC is equipped with an on-board Programmable Logic Controller (PLC). This allows

the operator to move critical functions of the catwalk simultaneously, positioning it precisely

where the trough needs to be on the rig floor with the push of a single toggle on the remote.

TAC 23

n Fully PLC Controlled: The catwalk’s on board PLC system controls

each main function when picking up and laying down tubulars. All

three main functions (front arm, rear arm, trough extension) are

controlled by 1 toggle switch offering quicker trip times because

the operator no longer needs to feather the trough to its end point

on the rig floor or home position.

n Open Belly Design: The TAC’s open frame design allows for quick

and effortless maintenance to the unit allowing the operator to

work in a safe an comfortable environment. The open belly also

offers a wide open view of the catwalk’s inner system, making it

simple to trouble shoot issues from outside of the frame, reducing

any possible downtime.

n Custom Tubular Presentations: When tubulars are brought to the

rig floor, the TAC 45 can be adjusted to fit the operator’s needs.

When presenting the tubular to the awaiting elevators, the TAC 45,

unlike other catwalks, offers multiple presentation options that can

effortlessly be programmed using the wireless remote.

n No need for Vdoor: The TAC catwalks are designed to be

independent of the rig and do not require a Vdoor to operate,

reducing the rig up time and integration time for initial placement

on the rig, the TAC can be spotted in front of the substructure and

simply plug and play.

n Multiple Substructures with one unit: The TAC systems, using the

front scissoring arms, can reach any rig floor within the maximum

height range limits of each model. This offers a huge benefit to

operators as the catwalk is now a useful tool that can be used on

multiple rigs, amplifying the investment.

n PLC Control Prolongs Life: Because the PLC controls the catwalk’s

movements, velocities and ramping into the end and home

position, the operator can expect to see longer use from the

catwalk with reduced amount of maintenance and replacement

parts. Less down time, more up time!

Because of the TAC’s open belly design, valuable time is saved during troubleshooting.

FEATUrES AND BENEFITS

Tesco Automated Catwalks are designed to achieve zero contact with personnel.

EQUIPMENT OVErVIEW

The TAC 45 is the largest catwalk in Tesco’s offering and is designed to be the

most adaptable hydraulic catwalk system in the world. The TAC 45 utilizes four

lift arms providing more strength, agility and reliability than the catwalk industry

standard. Utilizing the front scissor lift arms and rear cantilever arms, the TAC 45

can present tubulars to any rig floor at heights of up to 32 ft. The TAC 45 has a

100HP motor, a lifting capacity of 10,000 pounds (five tons), and can handle 20”

diameter tubulars and tubular products.

TAC 45

This model is designed specifically for smaller drilling rigs and snubbing rigs.

Unlike the TAC 45 and TAC 45M, the TAC 23 uses only two scissoring arms yet

maintains the ability to present tubulars to any rig floor at heights of 32ft. It can

be powered by a 60HP Electrical HPU and has a lifting capacity of 6,000 pounds

(three tons). TAC 23

A two-piece modular system, the TAC 45M was built to fit the need for a more

portable catwalk that could still perform and handle tubulars like the TAC 45.

Since the HPU can be detached for transportation and reattached upon arrival

onsite, the TAC 45M is more easily transported from location to location. This

feature also allows it to meet the requirements of strict transportation regulations

around the world. The TAC 45M is also Tesco’s unit of choice for offshore

operations.

*A pony sub is a non-permanent structure on which the catwalk may be placed. This structure can be used if the catwalk needs to be moved over wellheads during pad well operations. The pony sub also enables the catwalk to reach rig floors higher than the maximum reach of the catwalk.
