Abstract: According to one or more embodiments of the present disclosure, a riser may be operated by a method including repeatedly heating and cooling a riser between an operational temperature and a non-operational temperature. When the riser is heated from a non-operational temperature to an operational temperature, the riser undergoes thermal expansion. When the riser is cooled from an operational temperature to a non-operational temperature, the riser undergoes thermal contraction. The riser undergoes irreversible growth over repeated heating and cooling cycles, and the length of a lower section of an upper riser portion is sized to accommodate the irreversible growth from cycled thermal expansion of the riser.

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.

Abstract: According to one or more embodiments of the present disclosure, a riser may include a lower riser portion, where the lower riser portion terminates at an upper end of the vertical riser segment, and an upper riser portion including a lower end, where the lower end of the upper riser portion may be positioned around the upper end of the vertical riser segment of the lower riser portion. The riser may also include a first guide and a second guide each positioned on opposite sides of the interior of the lower end of the upper riser portion. The vertical riser segment of the lower riser portion may be guided in a direction substantially parallel with the outer surface of the first guide and the outer surface of the second guide when the lower riser portion expands or contracts due to changes in temperature.
