Abstract:
A positioning device (30) and an arrangement (30) for installing a mono-column platform (3) in the seabed (5) of the sea. The device is arranged at a first floating structure (10) and the platform is extending between the first floating structure and a second floating structure (12) so that a first end portion (20) of the platform is held by the first floating structure and a second end portion (22) of the platform (3) is held by the second floating structure (12). The device comprises attachment means (32) for holding the first end portion (20) of platform, and a first pivot (50) for pivoting the first end portion of platform so that the first end portion is reoriented towards the surface of the sea after that the second end portion of the platform has been released from the second floating structure.
Abstract:
Sistema para ensamblar un aerogenerador sin ayuda de grúas, que dispone de sistemas de elevación (8) dispuestos periféricamente a la torre (3), con una plataforma de elevación (11), una base (10) y un mecanismo de elevación interno. La plataforma de elevación (11) coopera con distintos útiles de conexión (16, 18 y 2x) que pueden soportarse sobre una columna auxiliar (15) y elevar o descender así los sucesivos módulos de la torre (3). El método para su ensamblaje es: preparar la cimentación (5) sobre el suelo (6) o sobre la plataforma marina, instalar el módulo básico (7), colocar periféricamente los sistemas de elevación (8). En caso de un aerogenerador offshore se procede con el montaje del tramo subacuático y tras abrir un orificio en la plataforma el mismo sistema de elevación permitiría sumergir dicho tramo subacuático hasta llegar al fondo. Una vez fijado dicho tramo, se procede a fijar y elevar la góndola (4), colocar el módulo superior (14) de la torre en el hueco creado, descender las plataformas de elevación (11), instalar la columna auxiliar (15) y la brida de conexión (16), elevar la góndola (4) con el módulo superior de la torre (14), colocar el módulo (17) en el hueco creado, desconectar la columna auxiliar (15) y descender las plataformas de elevación (11), instalar la columna auxiliar (15) y la pieza de conexión (18), elevar la góndola (4) con el módulo (14) y el módulo (17). Esto se repite con el resto de módulos hasta el fin del ensamblaje.
Abstract:
A method of producing oil and gas from a gathering manifold or a well. The method includes the steps of channeling field production into a sealed vessel (12) through an inlet pipe (10), and permitting oil and gas components of the field production to separate naturally from water and other fluids within the vessel (12). The method further includes the steps of evacuating the separated oil and gas from the vessel (12) via pipelines (20) attached to the vessel (12) at locations corresponding to the separated oil and gas, and pumping seawater into the vessel (12) to pressurize the vessel (12) and thereby aid in the production of oil and gas from the vessel (12).
Abstract:
Ce procédé comporte les étapes suivantes : - fixation réversible d'un organe de liaison (34) à une première extrémité de l'élément allongé (10); - disposition de l'élément allongé (10) dans une configuration sensiblement horizontale; - engagement réversible de l'organe de liaison (34) dans un organe de retenue (36); - pivotement de l'élément allongé (10) autour d'un axe sensiblement horizontal pour placer l'élément allongé (10) dans une configuration sensiblement verticale, l'organe de liaison (34) restant engagé dans l'organe de retenue (36); - descente conjointe de l'organe de retenue (36), de l'organe de liaison (34) et de l'élément allongé (10) dans l'étendue d'eau (12) à l'aide d'une ligne de descente; - détachement de l'organe de liaison (34) de la première extrémité de l'élément allongé (10), et remontée conjointe de l'organe de retenue (36) et de l'organe de liaison (34).

Abstract:
Zum Herstellen einer Verbindung einer Gründungsstruktur mit dem See- oder Meeresgrund wird erfindungsgemäß eine technische Lösung bereit gestellt, die die offshore auftretenden Lasten aus Installation und Betrieb eines Offshore-Bauwerkes durch Ausnutzung einer Kombination von lastaufnehmenden Buckets mit gleichzeitiger Nutzung des Schwerkraft-Effektes kompensiert. Der besondere Vorteil der Erfindung liegt in der Möglichkeit, Fundamente für Offshore-Bauwerke mit einer sehr geringen Schallemission zu installieren. Darüber hinaus können Kosten während der Offshore-Installation eingespart werden.
