Abstract

SUPORTE ARTICULADO PARA RISER é descrito um suporte articulado para riser que tem como função principal promovera conexão, com uma unidade flutuante, da extremidade de um riser proveniente de um poço no fundo do oceano, ou de outra plataforma, ou mesmo que partindo para a costa, seja rígido, flexível ou constituído pela combinação destes últimos, esteja este em uma configuração de lançamento em catenária au outra mais complexa. O cenário da instalação é de águas profundas. A presente invenção fundamenta-se em dois anéis (4 e 10) concêntricos, respectivamente dotados de eixos (El e E2), ortogonais entre si, dispostos perpendicularmente ao eixo longitudinal de um riser. Um sistema de cunha (8) abraça o corpo do riser na região em que este é canectado ao conjunto de anéis (4 e 10).ARTICULATED RISER SUPPORT An articulated riser support is described having as its primary function the connection, with a floating unit, of the end of a riser coming from a well at the bottom of the ocean, or from another platform, or even from the shore. , whether rigid, flexible, or a combination of the latter, whether it is in a catenary launch configuration or a more complex one. The scenario of the facility is deep water. The present invention is based on two concentric rings (4 and 10), respectively provided with orthogonal axes (E1 and E2) disposed perpendicular to the longitudinal axis of a riser. A wedge system (8) hugs the riser body in the region where it is connected to the ring assembly (4 and 10).
