Instances where tool joints connecting a casing running tool to the top drive have backed off are unfortunate, but preventable. Unexpected tool joint back off can be avoided by following proper make up procedures and with make-up verification after any large or sudden applications of reverse torque. While such occurrences are very rare, they can have serious safety consequences if not promptly identified.
As a safeguard to help avoid such instances, Volant has engineered and tested drop prevention accessories as a dependable and reliable protection during drilling or casing running operations that enhance rig floor safety. We currently offer two drop prevention products, V-LOK™ Tool Joint Lock and the Volant Tether Swivel Accessory.
