Beschreibung
Zusammenfassung:	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).
