Abstract
The present disclosure provides a system and method for supporting a catenary riser coupled to an offshore platform system including a pull tube and a pull tube stress joint for girth weld stress reduction and improved fatigue performance. A pull tube sleeve is coupled around a welded connection of the pull tube. The sleeve has a larger inner diameter than an outer diameter of the pull tube to form an annular space therebetween, and a fill material is filled into the space between the sleeve and the pull tube. The fill material provides a supportive coupling between the sleeve and the pull tube. The sleeve, the pull tube, or both can have gripping surfaces formed in or on their surfaces to retain the fill material in the space. The sleeve can be formed from a plurality of portions and be welded, fastened, or otherwise coupled around the pull tube.
