Abstract (en)
A fixed bottom transition joint for suspended pipe risers includes a structural member 2. This structural member is defined by a top surface 32 having a predetermined diameter and by a parallel bottom surface 34 having a diameter which is larger than the diameter of the top surface. Further defining the structural member is an outer surface 36 which extends between the top and bottom surfaces and optimally tapers from the bottom surface to the top surface. Finally, an inner surface 38 defines a longitudinal bore through the structural member.
