爆炸性断开
摘要：
一种联接系统，包括下部海洋立管组件，该下部海洋立管组件在底端具有连接器和至少一个联接到井口的防喷器压力控制元件，并且在上端具有连接器。爆炸性易碎紧固件用于将下部海洋立管组件上的连接器联接到至少一个防喷器压力控制元件上的连接器。一种用于将下部海洋立管组件与联接到海底井口的防喷器分离的方法包括，关闭防喷器中的至少一个压力控制元件，引爆将防喷器联接到下部海洋立管组件的至少一个爆炸性易碎紧固件，然后将下部海洋立管组件从防喷器中提起。
摘要（英）：

A coupling system includes a lower marine riser package having a connector at a bottom end and at least one blowout preventer pressure control element coupled to a wellhead and having a connector at an upper end. Explosively frangible fasteners are used to couple the connector on the lower marine riser package to the connector on the at least one blowout preventer pressure control element. A method for separating a lower marine riser package from a blowout preventer coupled to a subsea wellhead includes closing a least one pressure control element in the blowout preventer. At least one explosively frangible fastener coupling the blowout preventer to the lower marine riser package is detonated. The lower marine riser package is then lifted from the blowout preventer.
