Abstract
Perfeccionamientos en plataformas marítima flexibles sin elementos diagonales estructurales en su plano vertical, que permite las deflexiones horizontales debidas a fuerzas externas, caracterizados porque se dota a cada plataforma de una cubierta de trabajo de rigidez suficiente para evitar el exceso de deformación de la cubierta debido a las fuerzas del viento y de las olas que se transmiten a la plataforma, por lo que la cubierta permanece relativamente plana; una pluralidad de elementos de patas de sustentación tubulares conectados a la cubierta y que se extienden hasta el fondo de la masa del agua; una pluralidad de conjuntos de elementos de patas de sustentación, construyéndose cada uno de los elementos horizontales para presentar un esfuerzo de flexión virtualmente uniforme a lo largo de las fibras exteriores del elemento horizontal; y medios para variar la masa de la plataforma introduciendo agua en los elementos tubulares de las patas de sustentación y los elementos tubulares horizontales.
