For applications as described like the Challenger FSRU, the ASaP Phazer and LNG Sampler System combination is used for custody transfer of LNG with compliance to G.I.I.G.N.L., ISO 8943, tested against EN 12838.
Together with our Belgian partner GGS Oil & Gas Systems (GGS) ASaP executed an order for two Phazers (LNG probe-vaporizers) and one common intermittent LNG sampler. The Phazer is developed for direct insertion into the LNG transfer line. The Phazers and LNG sampler will be installed on the world’s largest FSRU which will be moored in Turkey.
A typical LNG mixture start to boil at -260°F (-162°C) at atmospheric pressure. For an application like LNG sampling at low pressure with Ship-to-Ship (StS) transfers, 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.
