BURRO test series

In 1980 the BURRO test series was conducted. These were much larger, with spills up to 40 m at injection rates of 12-18 mVmin. In all cases, the LNG tank liquid had a composition of over 83 mole % methane. The first five tests were conducted with no indication of an RPT. In BURRO-6, motion pictures clearly showed several strong RPT events late in the spill and at a location near the outer edge of the ice which formed on the pond around the spill pipe. Three RPTs were particularly sharp and water and LNG were violently ejected into the air no instrumentation was operating to indicate oveipressures either in the water or air, and no structural damage was done to the test facility. 

A summary of the BURRO test series parameters is given in Table VII. The colunm entitled spill-plate location needs some comment. In BURRO-2 through -8, the location of the spill plate relative to the water level changed due to normal pond evaporation. That is, the pond depth... 

It should be noted that, beginning with the earliest experiments, a tradition (which has not always been followed) was established by Lawrence Livermore National Laboratory of naming a test series with an animal name related to the NTS or the desert environment. This was done alphabetically beginning with the name Burro for the first LNG series conducted at China Lake, CA.
