... this problem (Palmer et al., 1974; Pesce et al., 1998; Croll, 2000; Lenci and Callegari, 2005). All of these models endeavour to give a precise evaluation of the SCR curvature in the touchdown zone, and to ensure continuity of displacement, gradient and shear force. As an example of these methods...

... Recently, analytical solutions, of the boundary-layer type, were developed for the static and dynamic curvature problems in the touchdown point (TDP) region of a catenary riser (Aranha, Martins & Pesce, 1997; Pesce et aI., 1997). Neverthless, the analysis was restricted to the infinitely...

... ABSTRACT Recently, the subcritical dynamics of catenary risers in the vicinity of the Touch Down Point (TDP) has been studied in depth (Aranha, Martins & Pesce, 1995: Pesce & Pinto, 1996), by means of asymptotic methods and boundary layer theory. The major outcome of those previous...

..., for a Steel Catenary Riser (SCR) and a Flexible Riser, through simple situations, where, in the absence of ocean current, a totally analytical solution can be constructed. 1. INTRODUCTION The design procedure for catenary risers is inherently cyclic, giving rise to a design spiral; see Pesce et aI, 1995...
