Here is my response to one of the question asked in DrillingAhead.com,
Making drill pipe stand while drilling !
As long as there is an experienced hands to supervise the job, I think there would be no problem. Also we do this in making up stands only and when the top drive is at a higher elevation while drilling to prevent any untoward incident.
We are using single latch elevator and a lifting cap for the drill pipe alternately with a weight ( we used a heavy tong jaw) to prevent the air tugger line from going to the roof! A lifting cap is used to pick up a single joint from the v-door into the mouse hole using one of the air hoist and then replaced with a single elevator on the top joint of the DP stand using the other air hoist where racking is being done. Lifting cap is designed for a single joint only. It is safer and faster to work with an iron roughneck in making up the stands.
If the company man allows this operation, then there is no problem doing this simultaneous jobs.
