Bore-Wrap is a simple application and can be completed with as few as 3 people or as many as 10.  The time to apply is usually measured in feet per minute.  With 3 people doing a girthweld protection, it is about 1.5 feet per minute.  With 6 to 10 people performing a mainline application it is about 3 feet per minute regardless of the diameter.  One key element is the volume of water that is available,  you can only progress at the speed that allows for the Bore-Wrap to be saturated.
