As time passed, the increasing severity of the sea conditions and the movements of the loose spud pile created forces beyond the limits of the pontoon and dovetail elements. The pontoon’s dovetail elements broke off tearing the metal plating. The pontoon got filled with water in the process and sank. The spud pile was still intact and the buoyancy of the spud pile turned it upside-down leaving the top part with the pontoon on the seabed and the other end above the surface.
