Floating Sub Tool (FST)
Volant’s FST is designed for casing drilling or running operations with top drive equipped rigs to supply
passively damped axial travel during connection making. The FST helps to prevent damage due to jarring
or sudden loading to casing or drilling equipment during day-to-day operations.
This patent pending architecture is capable of providing full hoisting loads in combination with full torque
values at all stroke positions. The FST is fully compatible with Volant’s Casing Running Tool with internal grip
(CRTi™) and external grip (CRTe™).
