blowout preventer

基本解释

First, remote-controlled robot submarines have been deployed to try to seal off the oil well altogether by activating a massive device called a blowout preventer.
首先，他们已经部署了遥控机器人驾驶的潜水艇潜入水下试图通过激活防喷器来关闭油井。
As the first diagram shows, the main component would be a containment assembly that could fit on top of a damaged blowout preventer, such as the one from which the Macondo oil poured forth.
如第一张图解所示，主要部件是能安装在一个受损的防喷器顶端的一个封存装置，例如马贡多井的原油就是通过防喷器涌出。
If the rate is at the low end of the range and was lower still before a key pipe on top of the blowout preventer was cut to accommodate the top hat, about half as much oil has been spilled so far.
假如现在这个比率是最低的、并且放在防喷器上方的关键性管道适应了高帽之前、仍然保持低比率，那时候泄漏的油约相当于现在已经漏掉量的一半。

The cap installed on the top of the well is basically a second blowout preventer.
