Abstract

L'invention concerne une sous-structure pour plate-forme flottante marine comprenant un ou plusieurs pontons inférieurs (1) sur lesquels (1) se dressent des colonnes pratiquement verticales à section circulaire sensiblement constante. Dans l'eau (13), cette sous-structure pilonne sous l'effet des forces de la houle auxquelles elle est exposée. Cette sous-structure peut comprendre une colonne centrale (3) surmontée d'une partie conique (4), qui durant le pilonnement, bouge sur la surface de l'eau. Dans une variante, cette sous-structure peut comprendre des éléments coniques montés sur l'extérieur d'une ou de plusieurs des colonnes (2), formant une ou plusieurs parties coniques, qui, lors du pilonnement, bougent sur la surface de l'eau.
