DEPLOYMENT AND DIRECT TIE-IN OF SUBSEA PIPELINES

A method of installing a subsea pipeline having a direct tie-in to a subsea structure. The method comprises, during introduction of the pipeline into the sea from a pipe laying vessel, applying a plastic deformation to a region of the pipeline at or close to an end of the pipeline to be tied-in and,...

Beschreibung
Zusammenfassung:	A method of installing a subsea pipeline having a direct tie-in to a subsea structure. The method comprises, during introduction of the pipeline into the sea from a pipe laying vessel, applying a plastic deformation to a region of the pipeline at or close to an end of the pipeline to be tied-in and, either during or following tie-in, elastically deforming said region to increase its radius of curvature. Un método de instalación de una tubería submarina que tiene una conexión directa con una estructura submarina. El método comprende, durante la introducción de la tubería en el mar desde un barco de tendido de tubos, aplicar una deformación plástica a una región de la tubería en o cerca de un extremo de la tubería a ser conectado y, ya sea durante o después de la conexión, deformar elásticamente dicha región para aumentar su radio de curvatura.
