Abstract
A supported riser apparatus may be housed at least partially within a vessel. The supported riser apparatus may include a riser including a non-vertical riser segment, a non-linear riser segment, and a vertical riser segment. The supported riser apparatus may further include a support member comprising a proximal end and a distal end. The proximal end of the support member may be connected to the non-vertical riser segment and the angle between the support member and the non-vertical riser segment may be from 15 to 75. The supported riser apparatus may include a support structure connected to the riser and the support member and an expansion guide connected to an interior surface of the vessel. The expansion guide may be shaped and positioned such that the support member slides across the expansion guide as the support member undergoes thermal expansion or thermal contraction.
