Semi-submersible platform for use in the open sea

Abstract

ABSTRACT: The invention relates to a semi-submersible platform comprising: an inner column and at least four outer columns, in which each of the inner and outer columns is made from reinforced concrete and comprises a resistant base, a shaft and a section located at a pre-determined height and having greater resistance. The semi-submersible platform also comprises a plurality of beams at the aforementioned pre-determined height, which connect each outer column to the inner column and to each adjacent outer column, and a plurality of anchor lines designed to be anchored to the more resistant section of each outer column. The semi-submersible platform also comprises a lower plate on which the columns are secured and which is reinforced with a plurality of beams that connect the base of each outer column to the base of the inner column and to the base of each adjacent outer column. The invention relates to a method for the construction of a semi-submersible platform.

RESUMEN: Una plataforma semisumergible que comprende: una columna interior y al menos cuatro columnas exteriores, donde cada una de dichas columnas interior y exteriores son de hormigón armado y comprenden una base resistente, un tronco y una sección de mayor resistencia a una determinada altura. La plataforma semisumergible comprende además una pluralidad de vigas a dicha determinada altura que unen cada columna exterior con la columna interior y con cada columna exterior adyacente, y una pluralidad de líneas de fondeo configuradas para ser ancladas a la sección de mayor resistencia de cada columna exterior. La plataforma semisumergible comprende además una placa inferior sobre la que se fijan las columnas reforzada por una pluralidad de vigas que conectan la base de cada columna exterior con la base de la columna interior y con la base de cada columna exterior adyacente. Un método de construcción de una plataforma semisumergible.
