Abstract

Au-dessous du tirant d'eau d'un système flottant en forme de coque, un guide 15 de colonnes montantes muni de tubes-guides 16 multiples est disposé le long du bouchain du bordé latéral de la coque. En tant que carénage, des éléments avant et arrière 20C de couverture sont mis en place de manière fixe à l'avant et à l'arrière du guide 15 de colonnes montantes. Des éléments supérieurs 20U de couverture et des éléments inférieurs 20D de couverture sont montés de façon à recouvrir les tubes-guides 16 qui dépassent vers le haut et le bas du corps principal du guide de colonnes montantes. Après que le système flottant de production, de stockage et de transbordement a été transporté jusqu'à une zone d'installation marine, les éléments supérieurs 20U de couverture et les éléments inférieurs 20D de couverture sont démontés par des opérations sous-marines, et des colonnes montantes sont montées dans chaque tube-guide 16.
