ABSTRACT
The practical significance of seabed/pipe interaction close to the TDP is related to the mechanics of a suspended length of pipe (Palmer et al., 1974). Most of the suspended span is essentially a catenary, in which the curvature is determined by the interaction between the submerged weight and the tension, and is
where ψ is the angle between the pipe axis and the horizontal, S is distance measured along the pipe,
w submerged weight per unit length, and U is the horizontal tension at the surface.
