Title (EN) SUBSEA PIG LAUNCHERS
(FR) LANCEURS DE RACLEURS SOUS-MARINS
Abstract:
(EN) A compact subsea pig launcher (16) comprises a tubular magazine (42) for holding a plurality of pipeline pigs (10) in longitudinal succession ready for launching successively into a subsea pipeline. The magazine (42) is shaped to define at least one turn such as a coil around an upright axis. Thus, a series of pigs are stored in longitudinal succession along a path that is curved in plan view around the upright axis. During launching, at least one of the series of pigs is advanced along the path with angular movement around the upright axis.
(FR) La présente invention concerne un lanceur de racleur sous-marin compact (16) comprenant un magasin tubulaire (42) destiné à contenir une pluralité de racleurs de conduite (10) en succession longitudinale prêts à être lancés successivement dans une conduite sous-marine. Le magasin (42) est formé pour définir au moins un tour de manière similaire à une bobine autour d'un axe vertical. Ainsi, une série de racleurs sont stockés en succession longitudinale le long d'un trajet qui est incurvé dans une vue en plan autour de l'axe vertical. Pendant le lancement, au moins un racleur de la série de racleurs est avancé le long du trajet avec un mouvement angulaire autour de l'axe vertical.
