Abstract
Verfahren zum Betreiben von Offshore-Anlagen mit geschweißter Stahlrohrfundamentkonstruktion und möglichen Brandherden, mit den folgenden Schritten: Befüllen der Stahlrohrkonstruktion mit einem Gas oder Gasgemisch auf einen Druck, der erheblich über dem Umgebungsdruck am Fuß der Fundamente liegt, Erfassen des Gasdrucks und Auswerten des Druckverlaufs des Gases und Ausgeben einer Warnmeldung bei einem schleichenden oder signifikanten Druckabfall, der nicht auf einem Umgebungstemperaturabfall beruht, dadurch gekennzeichnet, dass das in die Stahlrohrkonstruktion eingebrachte Gas oder Gasgemisch Distickstoff (N2), Kohlenstoffdioxid (CO2) oder Umgebungsluft ist, aus der der Sauerstoff weitestgehend abgeschieden ist, und bei Entstehen eines Brandes in der auf das Fundament aufgesetzten Anlage zum automatischen Ersticken des Brandes der Brandstelle zugeführt wird.Method of operating offshore installations with welded tubular steel foundation construction and possible sources of fire, comprising the steps of: filling the tubular steel structure with a gas or gas mixture at a pressure substantially above the ambient pressure at the foot of the foundations, detecting the gas pressure and evaluating the pressure profile of the foundation Gas and issuing a warning message at a creeping or significant pressure drop, which is not based on an ambient temperature drop, characterized in that the introduced into the steel pipe construction gas or gas mixture is dinitrogen (N 2 ), carbon dioxide (CO 2 ) or ambient air, from which the oxygen is largely deposited, and is supplied to the fire site in case of fire in the plant placed on the foundation for automatic stifling of the fire.
Description
Die Erfindung betrifft ein Verfahren zum Betreiben von Offshore-Anlagen mit geschweißter Stahlrohrfundamentkonstruktion und möglichen Brandherden.The The invention relates to a method for operating offshore installations with welded tubular steel foundation construction and possible sources of fire.
Die das Fundament von Offshore-Anlagen, beispielsweise Anlagen der Öl- und Gasindustrie sowie Windkraftanlagen oder Forschungsstationen bildenden geschweißten Stahlkonstruktion müssen in vorgeschriebenen turnusmäßigen Abständen auf das Vorliegen von Brüchen, Lochfraß oder Haarrissen untersucht werden.The the foundation of offshore installations, such as oil and gas installations as well as wind turbines or research stations forming welded steel construction have to at prescribed regular intervals the presence of fractures, Pitting or Hairline cracks are examined.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, das bei einer derartigen Anlage eine Brandbekämpfung ermöglicht.Of the Invention has for its object to provide a method that allows fire fighting in such a system.
Erfindungsgemäß wird diese Aufgabe gelöst durch den einzigen Patentanspruch.According to the invention this Task solved by the only claim.
Bevorzugt erfolgt das Befüllen der Stahlkonstruktion mittels eines elektrisch betriebenen Verdichters, das Erfassen des Drucks erfolgt mittels eines Drucksensors, das Auswerten des Druckverlaufs mittels eines Condition Monitoring Systems der Offshore-Anlage, über die auch die Abgabe einer Warnmeldung erfolgt.Prefers the filling takes place the steel structure by means of an electrically operated compressor, the detection of the pressure by means of a pressure sensor, the Evaluating the pressure profile using a condition monitoring system the offshore facility, over which also gives the delivery of a warning message.
Das in die Stahlrohrkonstruktion einzubringende Gas kann Umgebungsluft sein, aus der zur Verhinderung einer Korrosionswirkung das Salz abgetrennt ist und der Sauerstoff entzogen ist, so das das eingebrachte Gas im wesentlichen aus Stickstoff besteht; die Luft sollte auch entfeuchtet werden. Das in die Stahlrohrkonstruktion einzubringende Gas kann aber auch ein über Gasflaschen angeliefertes technisches Gas wie CO2 oder N2 sein.The gas to be introduced into the steel tube structure may be ambient air from which the salt is separated and the oxygen is removed to prevent corrosion, so that the gas introduced consists essentially of nitrogen; the air should also be dehumidified. However, the gas to be introduced into the tubular steel construction can also be a technical gas supplied via gas cylinders, such as CO 2 or N 2 .
Das in die Stahlkonstruktion eingebrachte sauerstoffarme oder sauerstofffreie Gas oder Gasgemisch kann im Brandfall über ein durch das Wartungspersonal verriegelbares Sicherheitsventil zu der Brandstelle in der auf das Fundament aufgesetzten Anlage zu automatischen Erstickung des Brandes zugeführt werden.The oxygen-poor or oxygen-free steel introduced into the steel structure Gas or gas mixture can in case of fire over one by the maintenance personnel lockable safety valve to the fire in the on the Foundation attached system to be automatically suffocated the fire.
