Experimental Tests and Qualification of a CFD Simulation Tool For Cryogenic Release Modelling through the JIP “FLNG Cryogenic Spillage Protection”

The Floating LNG (FLNG) and modularized onshore LNG plants are a new kind of facilities that involve new hazards. Technip has been a pioneer in the Engineering and Design of those projects with Shell Prelude Petronas SATU FLNGs and Yamal LNG.
One of the novel safety challenges of such projects is the accurate assessment of the risks from accidental releases of cryogenic fluid (i.e. steel brittle fracture and consecutive fire and explosion escalations) to define the location extent and rating of Cryogenic Spill Protection. From 2013 to 2015 TechnipFMC led the Joint Industry Project (JIP) FLNG Cryogenic Spillage Protection. One objective was to setup a qualification program at the best possible FLNG topsides scale to provide TechnipFMC and the Project sponsors (among which BG Group EDF Lloyds Register and Statoil) with improved knowledge of cryogenic releases and with an access to a software - EOLE- capable to better than ever predict the behaviour and impact of all types of cryogenic spillages.
This paper will present the extensive test program completed by the JIP and the capability of the EOLE Software.
