Abstract: A typical LNG mixture start to boil at -260F (-162C) at atmospheric pressure. For an application like Ship-to-Ship (StS) transfer of LNG, the typical pressures in the cross over manifolds are below 1 barg. This means that the LNG nearly start to reach its boiling point prior entering the sample probe. ISO 8943: 2007 stated Quote 6.2 Sample probe 6.2.1 Sample probes shall be located at points in the pipeline where the LNG is in a sub-cooled condition. The degree of sub-cooling at a sampling point shall be ascertained by observation of the temperature and pressure of the LNG at that point and comparing the temperature with the boiling point of the LNG at the same pressure as calculated from the composition of the LNG (see Annex A). In the case of multiple transfer lines, the sample probe shall be located downstream of the manifold, if one exists. Otherwise, each line shall be provided with a sampling point.
