Good question. Volant safety nubbins or thread protectors safeguard packer cups, aid in CRTi stabbing and help protect the coupling end face, threads, and shoulder. Their use is recommended, but when the rig is well aligned, the casing connection isn’t sensitive to CRTi stabbing or nubbins aren't available, operators/TRS providers may choose not to use them. A benefit of this is reducing personnel activity in the red zone.
