| A subsea well safing method and apparatus adapted 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 adapted to connect the marine riser to the BOP stack. 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 is actuated to physically separate the upper safing assembly and connected marine riser from the lower safing assembly that is connected to the BOP stack. | ||||||

| Systems and methods for activating a down hole tool in a wellbore. A piston is moveable from a first position to a second position for activating the down hole tool. The piston includes a first side exposed to a first chamber, and a second side exposed to a second chamber. A rupture member has a first side exposed to the first chamber and a second side exposed to a third chamber. The rupture member is configured to rupture when a pressure differential between the first chamber and the third chamber reaches a predetermined threshold value, at which point the rupture member allows fluid communication between the first chamber and the third chamber. When the rupture member is intact, the piston is in the first position, and when the rupture member ruptures, the piston moves to the second position and activates the down hole tool. | ||||||

| PURPOSE: A construction method of simultaneously adding bentonite and a PE pipe is provided to prevent the pump of grouting equipment from becoming clogged when bentonite is added since the bentonite is buried with a heat exchanger and thus is inflated by the water. CONSTITUTION: A construction method of simultaneously adding bentonite and a PE pipe comprises a bore(1), a 25mm PE heat exchanger(2), an inlet port(3), a water soluble polymer powder bag(4), a spacer(5) and a vent(7). If the water is added through the inlet port, the water soluble polymer powder melts in the water and the bentonite and the water make contact and thus the bentonite is inflated. The water soluble polymer powder bag is filled with the bentonite. The spacer makes the PE pipe heat exchanger maintain a straight line. The space is connected to the bentonite-filled polymer bag. | ||||||

| 본 발명은 농수의 공급원인 댐 또는 저수지로부터 멀리 떨어진 농토에 물을 공급하기 위해 지하에 매설되는 농수로타입에서 공급되는 물을 농토와 근접된 수로 측으로 분기하기 위해 일정 간격으로 설치되는 농수로 지하 밸브실의 방수 시공 방법에 관한 것으로, 기존 설치된 콘크리트 지하 밸브실을 철거하지 않고도 지하 밸브실의 내부에 물이 차이지 않도록 방수 시공할 수 있도록 한 것이다. 이를 위해, 밸브실(4)의 바닥면 크기에 따라 FRP를 원통부재(12)가 되게 마는 과정에서 파이프가 통과되게 절단함과 동시에 이음부위를 접착테이프(13)로 접착하여 실링하는 단계와, 상기 원통부재의 수직면상에 일정간격으로 보강파이프(17)를 위치시키고 접착테이프(18)로 고정시키는 단계와, 밸브실을 구성하는 콘크리트 벽체(10)와 원통부재(12)사이에 우레탄 폼(14)을 충진하여 원통부재(12)와 파이프(2)사이의 틈새를 폐쇄하는 단계로 이루어지므로 이미 시공된 콘크리트 벽체를 해체하지 않고도 밸브실을 완벽하게 방수 시공할 수 있게 된다. | ||||||

| A safety valve assembly for extradition of hydrocarbons includes a valve body including a passage duct, configured to be traversed by a production and/or drilling line. The valve body includes housings for a punch and counter-punch, arranged diametrically opposite to one another with a common longitudinal axis substantially perpendicular to the longitudinal axis of the valve. The punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe, and the counter-punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe. The punch and counter-punch are configured to allow the counter-punch to slidingly receive the punch in its interior to create two different shearing planes. The counter-punch includes a hollow part to slidingly receive the section of tubular material and the punch, in the linear movement during the shearing operation. | ||||||
