Abstract

- The slow motion dynamical behavior of a Differentiated Compliance Anchoring System (DICAS), subject to a range of directions of external excitation of constant magnitude, located in the Marlin Field, Campos Basin, Brazil, is assessed based on nonlinear stability analysis and bifurcation theory. Excitation consists of steady current, wind, and second order mean wave drift forces. Catastrophe sets are constructed in a two-dimensional parametric design space, separating regions of qualitatively different dynamics. Stability analysis defines the morphogeneses occur
