Consequence Analysis of Large-Scale Liquefied Natural Gas Spills on Water

“…However, measurements were not taken in the experiment of the flame propagation. After the Burro and Coyote series, the Falcon series tests (Brown et al, 1990) were conducted by LLNL in 1987. The main goal of the experiments were to provide a database on LNG vapor dispersion from spills in an environment with obstacles and to assess the effectiveness of vapor fences for mitigating dispersion hazards.…”

On the application of computational fluid dynamics codes for liquefied natural gas dispersion

“…From these tests, the best were selected to be benchmark tests for dispersion model validation. These include: Burro 3, 7, 8, 9, Coyote 3, 5, 6, Falcon 1, 3, 4, and Maplin (Shell) 15,27,29,34,35,39,56. A summary of these tests, except for Falcon, was developed by Ermak et al [38] specifically for model validation and includes key parameters required to run the models for each test, such as the Monin-Obukhov parameters, roughness lengths, humidity, LNG composition, spill rate, etc.…”

Burro information is available from the Burro Data Report [9] and from several analysis papers [41,42] and Coyote information from the Coyote Data Report [25,26] and several analysis papers [27,41].…”

Lessons learned from LNG safety research

“…In addition to the other hazardous materials of interest to these other industry and government sponsors, the US Department of Transportation and Gas Research Institute decided to sponsor an additional series of LNG tests to evaluate the effectiveness of a vapor containment fence or curtain. These tests were called the Falcon series and were conducted by LLNL at the newly constructed STF in 1987 [13].…”
