Any leak or failure results in loss of control line pressure, acting to close the safety valve and render the well safe.

任何的渗漏或损坏都将造成控制管线压力的损失，这时关闭安全阀并确保井的安全。

They're making plans now for -- even as they drill these two relief wells that optimistically will take quite some time -- how do we plug this leak either through using the robotics to effect the valve -- how are we dispersing this so that that oil never gets to the top and then through a natural system gets -- largely dissipates at the bottom?
