What is back tension during the umbilical installation and service?
(OP)
Guys, I was involved a project on the umbilcal analysis. I was confused about the 'back tension' . Anyone have information about this?

1) the tension on the seaward side of the tensioner = the lay tension
2) a usually lower tension between the reel and the tensioner = the back tension

My further question was that after the umbilical was laid on the seabed, some of them are taut or just 'sit' on the seabed without any tension? I heard it might be taut. When it was taut, there should be a tension in the umbilical, how to call this force and how big it was, how to detemine?
thanks again.
