Abstract

"âNCORA DE LEITO MARINHO". Trata-se de uma âncora de sucção (10) que compreende um caixão (12) com uma parede lateral (14), um fundo aberto (22) e um topo fechado (26) que definem o volume interno do caixão. Quando a âncora é colocada sobre um leito marinho (100) de lama fluente, um conector de topo (28) permite a conexão temporária de uma bomba (200) para aspirar a lama (102) do leito marinho através do fundo aberto para dentro do interior do caixão, a borda de fundo (20) da parede (14) do caixão permitindo que a âncora corte para dentro e se torne embutida dentro do leito marinho (100). Para se aumentar a resistência da âncora (10) embutida à retirada. O caixão é internamente dotado de um dispositivo de retenção de solo de leito marinho (30) que aloja e retém a lama durante o embutimento da âncora. O dispositivo de retenção de solo de leito-marinho compreende um recipiente aberto no topo preso dentro do caixão, o topo aberto (38) sendo localizado imediatamente abaixo do topo fechado (26) do caixão. Pela formação da parede (36) do recipiente como um cone convergente para baixo, a passagem (102) da lama para cima além do lado externo do recipiente (30) durante o embutimento da âncora é minimamente impedida. Assim como melhora a estabilidade e o desempenho das âncoras de sucção, a invenção pode ser também aplicada para igualmente aperfeiçoar a estabilidade e o desempenho de bases de gravidade embutíveis e âncoras de leito marinho embutidas por forças mecânicas direcio"SEA ANCHOR". It is a suction anchor (10) comprising a casket (12) with a side wall (14), an open bottom (22) and a closed top (26) defining the internal volume of the casket. When the anchor is placed over a flowing mud seabed (100), a top connector (28) allows a temporary connection of a pump (200) to suck the seabed mud (102) through the open bottom into the inside the coffin, the bottom edge (20) of the coffin wall (14) allowing the anchor to cut inward and become embedded within the seabed (100). To increase the resistance of the embedded anchor (10) to the withdrawal. The coffin is internally provided with a seabed soil retaining device (30) which houses and retains the mud during anchor inlay. The seabed soil retention device comprises a top open container trapped within the coffin, the open top (38) being located just below the closed top (26) of the coffin. By forming the container wall (36) as a downwardly converging cone, the passage (102) of the sludge upwardly beyond the outer side of the container (30) during anchor inlay is minimally prevented. As well as improving the stability and performance of suction anchors, the invention can also be applied to further improve the stability and performance of built-in gravity bases and seabed anchors by directional mechanical forces.
