Re: [MW:11243] Piggy-back pipeline installation

You should probably think of using the deck in welding the piggy back and tie it up on the mainline just before the stinger.

Hi everyone¡¡¡
 
We are tendering for a 24" Ø and 4" Ø piggy-back  pipeline project.
 
I'm looking for a operational procedure or technique to install the pipelines. I know that the 4" Ø piggy-back pipeline is holded on the 24" Ø carrier pipeline, but how to weld the 4" Ø field joints and put it onto the 24" Ø pipeline inside the ramp of the barge?
 
Thanks for your time and help.
