Tension-Assist Capstan

As part of our integrated risk management system, our 18,000-lb tension-assist capstan is designed to handle virtually any situation. We can prevent cable damage at higher tensions than ever before. In deep and ultradeep wells, this capstan is a critical component that enables us to complete your operation safely

Optimized Performance
Many capstans are designed to constantly work against the force of the drum. Our capstan is designed using an assist system that takes the direction of the drum as input. The drum and capstan are always working together.

Mounting Options
Unlike some competitive capstans, our capstan allows for flexible mounting options. Depending on the situation and client preference, the capstan can be mounted on the deck or mounted in the derrick.

Improved Safety
In addition to optimized performance, our powered capstan offers improved safety when it’s mounted in the derrick. Not only are there fewer surface components exposed to high tension, but that tension is focused straight down the well. If there is a problem, the high-tension energy in the cable is directed into the hole—not on the rig floor or with the rig-up equipment. It has the added benefit of significantly reducing the amount of destructive torque and tension applied to the cable and rig-up equipment.

Our derrick-mounted configuration can provide the safest system in the industry.
