摘要： A ram or shutter device includes rams operable between an open position withdrawn from a bore to a closed position to contact a tubular disposed in the bore, the rams may not seal the bore. A well system in accordance to an aspect of the disclosure includes an assembly providing a bore in communication with a wellbore, a device operable to shear a tubular disposed in the bore, and a shutter device having rams operable between an open position withdrawn from the bore to a closed position contacting the tubular in the bore.

摘要： A subsea well safing method and apparatus to secure a subsea well in the event of a perceived blowout in a manner to mitigate the environmental damage and the physical damage to the subsea wellhead equipment to promote the ability to reconnect and recover control of the well. The safing assembly is connectable to a subsea well and a marine riser. Pursuant to a safing sequence, the well tubular is secured in the upper and lower safing assemblies and the tubular is then sheared between the locations at which it has been secured. Subsequently, an ejection device may be actuated to physically separate the upper safing assembly and the connected marine riser from the lower safing assembly the subsea well.
摘要翻译： 一种海底井安全方法和装置，以在发生感知井喷的情况下，以减轻对海底井口设备的环境破坏和物理损坏的方式来确保海底井，以促进重新连接和恢复井的控制能力。 安全组件可连接到海底井和海洋立管。 根据安全的顺序，井管被固定在上部和下部安全组件中，然后将管状物在其已经固定的位置之间剪切。 随后，可以启动排出装置以将上部安全组件和连接的海洋立管从海底井的下部安全组件物理分离。

摘要： A subsea well system includes a safety assembly connected between a marine riser and a subsea wellhead, and an ejector bollard connected with the safety assembly and having a piston operable from a retracted position to an extended position to push an upper portion and a lower portion of the safety assembly apart and thereby physically separate the marine riser from the subsea wellhead.
