Abstract

Patente de Invenção: <B>"EMBARCAçãO SEMI-SUBMERSìVEL DE MOVIMENTO DE CURSO DE ELEVAçãO SUAVE"<D>. Uma embarcação semi-submersível 10, adaptada para resistir ao movimento de elevação de curso, que inclua uma pluralidade de colunas de suporte 16, cada uma apresentando uma extremidade superior 19 e uma extremidade inferior 23. Uma cobertura 39 se encontra interligada entre a pluralidade de colunas de suporte 16, em locais sobre as colunas 16, próximos às extremidades superiores 19 das mesmas. A cobertura 39 é uma estrutura em formato de caixote. Um pontão anelar 43 se encontra conectado à pluralidade de colunas de suporte 16, em locais próximos às extremidades inferiores 23 de cada uma das colunas 16. Cada coluna de suporte 16 apresenta um eixo longitudinal 29, que fica inclinado para cima e para o interior, a partir do pontão anelar 43, até a cobertura 39 e o eixo longitudinal estando orientado de forma substancialmente radial, a partir de um ponto central 13 da embarcação 10. Um ângulo de inclinação de coluna das colunas de suporte 16 se aproxima por, pelo menos, cinco graus da vertical. O pontão anelar 43 é de formato retangular e, segundo uma variação, é de formato substancialmente quadrado, apresentando porções de quina de pontão 49, interligadas através de porções de pontão alongadas 56. O pontão anelar de formato quadrado apresenta uma linha central 73, interceptando pontos centrais 79 de seções transversais tomadas de forma vertical 76 do pontão de formato quadrado 43. As porções de pontão alongadas 56 compreendem quatro estruturas em formato de caixote 59, cada uma apresentando uma configuração em seção transversal, tomada verticalmente, substancialmente de quatro lados.Invention Patent: <B> "SEMI-SUBMERSIBLE VESSEL OF SOFT LIFTING COURSE MOVEMENT" <D>. A semi-submersible vessel 10, adapted to withstand the lifting stroke, which includes a plurality of support columns 16, each having an upper end 19 and a lower end 23. A cover 39 is interconnected between the plurality of support columns 16, in places on the columns 16, close to the upper ends 19 of them. Cover 39 is a crate-like structure. An annular pier 43 is connected to the plurality of support columns 16, in locations close to the lower ends 23 of each of the columns 16. Each support column 16 has a longitudinal axis 29, which is tilted upwards and inwards, from annular pier 43, to cover 39 and the longitudinal axis being oriented substantially radially, from a central point 13 of the vessel 10. A column tilt angle of the support columns 16 is approached by at least , five degrees from the vertical. Ring pier 43 is rectangular in shape and, depending on one variation, is substantially square in shape, with portions of corner piers 49, interconnected through elongated pier portions 56. The ring shaped square pier has a center line 73, intersecting central points 79 of cross sections taken vertically 76 from the square shaped pier 43. The elongated pier portions 56 comprise four crate-shaped structures 59, each having a cross-sectional configuration, taken vertically, substantially on four sides.
