Abstract

Hang-off and/or torque 1 features are provided on the pipes and/or the connections of a high-pressure riser. The hang-off features may be useful to support the weight of the full length of the riser. Accordingly, the hang-off may be done directly in the middle of the connection, where the strength is the greatest. Also, by using the torque features, it is possible to accommodate large torque values. Accordingly, a large torque resistance may be provided while an upper pipe is being made up. A make-up tool taking advantage of the hang-off and/or torque features permits assembling the high-pressure riser more automatically and with less manual intensive labor.
