Abstract
(EN)
A method of installing a subsea pipeline for tie-in to a subsea structure. The method comprises laying, using a pipe laying vessel, an intermediate section of the pipeline on to a pipe restraint device, wherein the pipe restraint device is at or near the subsea structure, or is at or near a location at which a subsea structure will be installed, and the pipe restraint device restricts transverse movement of the pipeline. The intermediate section of the pipeline is configured to be tapped at or near the pipe restraint device for providing fluid communication between the pipeline and the subsea structure.
(FR)
L'invention concerne un procédé d'installation d'un pipeline sous-marin pour le raccordement à une structure sous-marine. Le procédé consiste à poser, en utilisant un navire de pose de tuyau, une section intermédiaire du pipeline sur un dispositif de retenue de tuyau, le dispositif de retenue de tuyau étant au niveau ou à proximité de la structure sous-marine, ou étant au niveau ou à proximité d'un emplacement auquel une structure sous-marine sera installée, et le dispositif de retenue de tuyau limitant le mouvement transversal du pipeline. La section intermédiaire du pipeline est configurée pour être raccordée au niveau ou à proximité du dispositif de retenue de tuyau pour assurer une communication fluidique entre le pipeline et la structure sous-marine.
