20080309077 | Method and Installation for Connecting a Rigid Submarine Pipe and a Flexible Submarine Pipe - A method and an installation for connecting a rigid submarine pipe and a flexible submarine pipe. The rigid pipe terminates in a free connection end. The flexible pipe has a flow-line portion and a suspended portion. The flow-line portion has an input end connected to the free connection end. The installation comprises an anchoring device to hold the flow-line portion anchored at an anchor point and to allow the flow-line portion to form an undulation. The anchoring device is suitable for holding the anchor point at a distance and close to the free connection end to form the undulation between the anchor point and the free connection end. | 12-18-2008 |
20100018717 | FLEXIBLE RISER PIPE INSTALLATION FOR CONVEYING HYDROCARBONS - The invention relates to a riser pipe installation that comprises a flexible duct of the non-bound type, the duct being vertically arranged between a mechanical connection with a submerged buoy at the stub on the one hand, and a mechanical connection with the seabed at the bottom on the other hand, wherein fluid connections are provided at the stub and at the bottom for connecting the riser pipe with surface equipment on the one hand and bottom equipment on the other hand; the bottom of the pipe is located at a depth of at least 1000 m where it is submitted to a computable maximum reverse bottom effect F, while the buoy is oversized in order to generate at the bottom of the riser pipe a reaction tension T higher than at least 50% or even 100% of the computable maximum reverse bottom effect F applied at the bottom of the pipe. | 01-28-2010 |
20110020067 | METHOD OF INSTALLING AN UNDERWATER RISER - A method of installing an underwater riser includes anchoring an installation to the seabed; coupling a tubular pipe to the installation; equipping the installation with a submersible float; submerging the float and the pipe, while the float and the pipe are being held from a surface vessel; a cable and a return device are installed on the seabed installation so that the cable can be connected to the pipe; attaching a submerged hauling buoy to the hauling cable; then removing ballast from the float in order to compensate for the tensile forces corresponding to the weight of the float and the pipe and to some of the load applied to the cable; and finally, anchoring of the hauling buoy to the installation, and gradually releasing the float. | 01-27-2011 |
