    Hi,

    I am facing a problem in Tie-in spool design which connects Pre-installed Riser and Pipeline. The Expansion in the pipeline is 755mm and Virtual Anchor length is 1788m. The concerete thickness of pipeline is 50mm. the maximum displacement allowed near riser bend is 200mm, even after providing 2 90 degree bend(Expansion Spool) i am not able to limit the displacement to 200mm as the displacement is coming as 500mm. I am following the design of DNV 1981. Can anybody tell me how to minimize the displacement?

    Regards,

    Rajath

      Locate the expansion loop at the end near the riser. Use Stopper near the riser.
