The main advantages are improved safety (by reducing number of people and pieces of equipment on the rig floor), improved efficiency (by packaging casing make-up, fill/circulate, and hoisting in a single tool), and the abiltiy to rotate while running casing.
Something not mentioned is that this is the first time this rig ran the tool. They run roughly 10 jts per hour on this rig, but there is no NPT for fill and circulate, and if there if trouble, it can be addressed without delay.
I worked three years with this tool in Colombia. It is very good and works perfectly.
Love this tool. Use the internal and external tools. Very compact, solid, fast, and easy to use. Volant #1.
