Refrigerated hydrocarbon and non-petroleum based liquefied gaseous fuels - Calibration of membrane tanks and independent prismatic tanks in ships - Manual and internal electro-optical distance-ranging methods (ISO 8311:2013)

ISO 8311:2013 specifies a method for the internal measurement of membrane tanks used in ships for the transport of refrigerated light hydrocarbon fluids. In addition to the actual process of measurement, it sets out the calculation procedures for compiling the tank capacity table and correction tables to be used for the computation of cargo quantities. ISO 8311:2013, with some modification, can also be applicable to the calibration of independent prismatic tanks.

Gekühlte Kohlenwasserstoffe und verflüssigte, nicht auf Erdöl basierende gasförmige Brennstoffe - Kalibrierung von Membrantanks und unabhängigen Prismentanks in Schiffen - Manuelle Messung und Innenmessung nach dem elektrooptischen Distanzmessverfahren (ISO 8311:2013)

Diese Internationale Norm legt ein Verfahren zur Innenmessung von Membrantanks in Schiffen, die für den Transport von durch Abkühlung verflüssigten leichten Kohlenwasserstoffen vorgesehen sind, fest. Außer dem Messvorgang selbst werden die Verfahren beschrieben, mit deren Hilfe sich Tabellen für die Tankkapazität und Korrekturtabellen zur Berechnung der mengenmäßigen Schiffsladung aufstellen lassen. Diese Internationale Norm kann mit einigen Modifikationen auch für die Kalibrierung unabhängiger Tanks in prismatischer Form angewendet werden.
Für die in dieser Internationalen Norm beschriebenen Verfahrensabläufe wird bei der manuellen Messung von Membrantanks zum Abstützen der Messgeräte das Gerüst verwendet, mit dem die Membran aufgestellt wurde; für das interne elektrooptische Distanzmessverfahren (EDM) sollten jedoch andere Hilfsmittel für den Zugriff auf die benötigten Messpositionen angewendet werden.

Hydrocarbures réfrigérés et combustibles gazeux liquéfiés à base non pétrolière - Étalonnage des réservoirs à membrane et réservoirs pyramidaux - Méthodes manuelles et par mesurage électro-optique interne de la distance (ISO 8311:2013)

L'ISO 8311:2013 spécifie une méthode pour le mesurage interne des réservoirs à membrane équipant les navires transporteurs d'hydrocarbures légers réfrigérés. Outre le processus de mesurage proprement dit, elle établit les méthodes de calcul permettant d'élaborer la table de jaugeage du réservoir ainsi que les tables de correction à utiliser pour le calcul des quantités de cargaison. L'ISO 8311:2013 peut également s'appliquer, moyennant quelques modifications, au jaugeage des réservoirs pyramidaux autoporteurs.
