The Progressive Safe Tension Tool (STT) was designed to eliminate the potential for a loss of control situation which may be experienced when setting a tubing sting in tension using the standard field procedure. While tension is pulled into the tubing string using the STT there is no need to remove the BOP’s or to overstretch the tubing, which is the case when using Low Line Slips.
The STT is installed between the tubing hanger and the production tubing and once the tubing hanger is landed, isolating the annulus, tension is pulled into the tubing string and safely locked into place without losing well control. The tool allows for complete rotation of the tubing when setting downhole tools such as anchors or packers.
