BIFURCATION OF STATIC EQUILIBRIUM OF A SEMISUBMERSIBLE IN WAVES

This paper reviews the phenomenon of the steady tilt of a semisubmersible from the point of view of the theory of bifurcation. The problem is similar to that of the buckling of an elastic structure, with the wave amplitude playing the role of the critical load. Depending on the wave number, the bifurcation can be "subtle", as in the case of a Euler beam, or "catastrophic", as in the case of shells and arches. Experimental results on a simplified submerged structure show very good agreement with the theoretical prediction from the viewpoint of second-order wave theory.
