I should also add the LMRP is not intended to block or stop the flow of oil. The box is designed to capture the leak and bring the oil and gas to the surface for processing. The first box failed because it froze up based on the energy changed when the methane expanded. Just like an aerosol can cools when you release the contents. This time around the box is smaller and modified to heat the contents in an attempt to eliminate the freeze up issues.
[QUOTE=Walton;34290]I don’t know much about the LMRP, but would it be possible to fill it with mud before placing on top of the riser? Does it have a mechanism to close the bottom end of it or the hose?[/QUOTE]
