Abstract
A state-of-the-art review of the riser analysis is presented. The papers starting with the Mohole project in early 1950 to the present day covering the analysis of a riser are discussed. It is shown how the earlier static analysis of the problem is superceded by a more advanced dynamic analysis with the advent of the modern computer. Several controversial areas in the analysis, e.g., the non-linear drag terms, the effective tension in the system, the buoyant weight of the riser and contents, the non-linearity due to large deformations, etc., are reviewed and the deficiencies of many works in these areas are pointed out. A detailed derivation of the horizontal equation of motion of the riser and interpretation of the various terms in the equations have been provided.
