Semi-submersible triangular platform for use in the open sea

Abstract

ABSTRACT: The invention relates to a semi-submersible platform comprising: an inner column designed to improve buoyancy and three 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 the other two outer columns, 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 the other two outer columns. The invention relates to a method for the construction of a semi-submersible platform.

RESUMEN: Una plataforma semisumergible que comprende: una columna interior configurada para dotar de mayor flotabilidad y tres 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 las otras dos columnas exteriores, 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 inferio 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 las otras dos columnas exteriores. Un método de construcción de una plataforma semisumergible.
