Abstract

In offshore waters an all-steel, flexible marine riser assembly may be used to transport production fluid from a submerged wellhead to a floating production facility. The marine riser assembly consists of an array of flexible steel flowline bundles which form a cantenary shape as they bend upward from the marine bottom to the production facility.
