Abstract:
A riser includes a first pipe stand and a second pipe stand, wherein at least the first pipe stand includes a length of pipe and a coupling that is coupled to an upper end of the pipe, the coupling including a body. At least the first pipe stand further includes an upper support member and a lower support member, both of which are mechanically coupled to the body, the upper support member including an elevator engagement support shoulder and the lower support member including a riser weight load support shoulder that is adapted to support a weight load of the riser from a support structure, wherein the coupling with the upper support member and the lower support member coupled thereto is adapted to be lowered through the support structure after a lower end of the second pipe stand has been coupled to an upper end of the coupling.
