The orientation of the test rig could be varied to measure both upward and downward flow out of the manifold.
Research determined the most appropriate manufacturing processes and materials so that the test rig could be manufactured in the material laboratories.
Based on the data analysis and the photographs recorded from the experiments, the laboratory scale experimental rig could be used to simulate the hot zone formation mechanism and the boilover event safely and successfully.
The model elevator within the rig could be immersed in 19 feet of water, and used banks of compressors to strictly regulate movement.
But the warning systems were turned off so the rig could be pushed to the breaking point, even after receiving 18 citations for safety violations from the Coast Guard.
The court ruled that Yekaterina Zaspa, a Russian medic on the Arctic Sunrise who was not among those who tried to climb the rig, could be released on 2 million roubles ($61,300) bail.
