Title (EN) PRESSURE PROTECTION FOR AN OFFSHORE PLATFORM
(FR) PROTECTION CONTRE LA PRESSION POUR UNE PLATE-FORME EN MER
Abstract:
(EN) A method for pressure protection of an offshore platform (14, 16) of an oil and gas installation, the offshore platform (14, 16) being connected to source of hydrocarbons via a pipeline (18), the method comprising: using a safe link device (62) at the pipeline (18); wherein the safe link device (62) is located subsea and outside of the safety zone of the platform (14), (17); protecting the platform via a subsea High Integrity Pressure Protection System (HIPPS) for the platform (14, 16) and/or the pipeline (18); and wherein the safe link device (62) is arranged to activate to release pressure from the pipeline (18) when the pressure exceeds a preset threshold that is above the normal ultimate limit state pressure for the platform (14, 16).
(FR) Cette invention concerne un procédé de protection contre la pression d'une plate-forme en mer (14, 16) d'une installation de pétrole et de gaz, la plate-forme en mer (14, 16) étant reliée à une source d'hydrocarbures par l'intermédiaire d'un pipeline (18), le procédé comprenant les étapes consistant à : utiliser un dispositif raccord de sécurité (62) au niveau du pipeline (18), le dispositif de raccord de sécurité (62) étant situé sous la mer et à l'extérieur de la zone de sécurité de la plate-forme (14), (17); protéger la plate-forme au moyen d'un système sous-marin de protection contre la pression à haute intégrité (HIPPS) pour la plate-forme (14, 16) et/ou le pipeline (18), et le dispositif de raccord de sécurité (62) étant conçu pour s'activer afin de dégager de la pression à partir du pipeline (18) lorsque la pression dépasse un seuil prédéfini qui supérieur à la pression limite finale normale pour la plate-forme (14, 16).
