Abstract

The present invention relates to a fire safety valve system to be installed in connection with a hydraulic pipeline, which provides hydraulic pilot liquid to a sub sea safety valve installed at or near a wellhead of an oil or gas well, said fire safety valve system comprising at least a pressure relief facility and a blocking facility, said pressure relief facility comprising a fusible plug, where said fusible plug is a temperature sensitive device comprising means that, when released at a certain temperature level, will relieve the pressure of the hydraulic pipeline to the ambient pressure, where said blocking facility comprises one or more mechanical blocking means that when activated blocks the hydraulic pipeline, where said fire safety valve system further comprises a standardized connection flange for connection to said hydraulic pipeline.
