[QUOTE=company man 1;34697]The reason I ask this is I am wondering if a set of hanging rams would be expected to hold pressure also ? & I can’t even see the advantage of weight hanging rams being part of the emergency shut in system on the rig. Please understand I am not questioning your personal knowledge on subsea BOPs, but rather the thinking behind this engineering.[/QUOTE]
Simple answer is … Yes. ie hang off and hopefully hold pressure.
Better answer would be “hang-off” [B]and[/B] close ano ram or annular for backup.
