  • Publication number: 20240100496
    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.
