摘要： A riser for use in subsea operations that is parked subsea deployed as needed onto wellheads disposed proximate where the riser is parked. A base anchored into the seafloor provides a pedestal for parking the riser. The riser emits a beacon signal so it can be located when needed. When parked, the riser can be kept in a vertical orientation by a buoyancy module mounted on an upper portion of the riser. A workboat, or other vessel, attaches to the parked riser and positions it onto a designated wellhead. An extension connects the riser to platform or other vessel above the sea surface.

US08567510B2 Pressure actuable downhole tool and a method for actuating the same 有权

摘要： Pressure actuable downhole tool such as a packer and a method for actuating the same typically uses a control line to trigger a configuration change in the tool in which a communication line is opened between the throughbore of the tool and apressure responsive actuator, allowing the pressure responsive actuator to be set by downhole fluid pressure applied via the throughbore. Thus the pressure from the control line is used to trigger actuation of the tool, but the throughbore pressure is used to set the tool. The advantage of this activation mechanism is that the tool can be set even when pressure supplied by the control line is insufficient to fully actuate or set the tool, and in certain embodiments, the tool can be set using much higher tubing pressure than could be supplied through the control line, thereby allowing more reliable and instantaneous setting than tools set using control line pressure alone.
摘要翻译：诸如封隔器的压力可致动的井下工具和用于致动该压力的方法通常使用控制线来触发工具中的配置变化，其中在工具的通孔和压力响应致动器之间打开通信线，允许压力响应致动器由通过通孔施加的井下流体压力设定。因此，来自控制线的压力用于触发工具的启动，但是通孔通过压力来设定工具。该激活机构的优点在于即使在由控制线提供的压力不足以完全致动或设置工具的情况下也可以设置工具，并且在某些实施例中，可以使用比所提供的更高的管道压力来设定工具通过控制线，从而允许比仅使用控制线压力设置的工具更可靠和瞬时的设定。

摘要： A seal element (120, 126) for sealing a conduit is described. The seal element comprises a frusto conical portion (28) and a first lip (30) extending from an external edge of the frusto conical portion, the lip being adapted to be pivoted into engagement with a conduit surface. In a described embodiment, two seal elements are provided on a plug (10) for sealing a conduit (16), the seal elements facing in opposite directions to seal from above and below.
摘要翻译：描述了用于密封导管的密封元件（120,126）。密封元件包括截头圆锥形部分（28）和从截头圆锥形部分的外部边缘延伸的第一唇缘（30），所述唇部适于枢转成与导管表面接合。在所描述的实施例中，两个密封元件设置在用于密封导管（16）的插头（10）上，密封元件面向相反方向以从上方和下方密封。
