HotPipe JIP: Design Guidelines for HP/HT Pipelines

Abstract: Recent development plans envisage the transport of hydrocarbons at temperature and pressure conditions far more severe than in past projects. Technical feasibility of certain inter field lines was put in doubt as a consequence of application of design guidelines currently in force. This fact gave rise to a critical review of design criteria. The HotPipe Project is a Joint Industry Research and Development Project, whose overall objective is to prepare a DNV Recommended Practice to be used in structural design … Show more

“…Buckling analysis of pipelines has created considerable interest in the past due to the complexities involved in the analysis. JIP projects [11][12] have provided a general overview of buckling phenomena and solutions derived from classical theory. However, the separate effects of soilpipeline interaction, pipe material and geometry on the buckling initiation load were not properly identified and discussed.…”

“…The axial pipe-soil stiffness is given as [17] 𝑘𝑘 𝑥𝑥 = 𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝜃𝜃 𝐷𝐷 (11) where kx is the axial soil stiffness, m is the constant of shear modulus (G = mz, z is the depth below the pipe), and θD is the embedment angle of the pipe as discussed in the previous paper. The axial elastic stiffness, kx span a range of 0.04 to > 200 kN/m 2 was considered here.…”
