    • An apparatus, system and process for deployment of subsea drilling equipment through a moon pool of a drilling vessel is disclosed. The drilling equipment may include a subsea mudlift pump (MLP) that is configured to be deployed below the surface of the ocean and is adapted for conducting dual gradient drilling (DGD) operations. In the apparatus and process, the MLP may be suspended temporarily aboard the vessel by a holding mechanism. The MLP may be combined first with a lower marine riser package (LMRP) prior to suspension of the MLP and/or MLP/LMRP aboard the drilling vessel. An equipment combination, comprising at least a MLP and a LMRP, may be with a BOP, the mating occurring at a position below the surface of the ocean. In one aspect, the BOP may be separately deployed into the ocean, and then subsequently mated subsea with the LMRP and/or a MLP/LMRP combined equipment package.
    • 公开了一种用于通过钻井船的月球池部署海底钻井设备的装置,系统和过程。 钻井设备可以包括被配置为部署在海洋表面下方并且适于进行双梯度钻井(DGD)操作的海底制泥机泵(MLP)。 在设备和过程中,MLP可以通过保持机构暂时悬挂在船上。 在MLP和/或MLP / LMRP悬挂在钻井船上之前,MLP可以首先与较低的海洋提升管(LMRP)组合。 包括至少MLP和LMRP的设备组合可以具有BOP,配合发生在海洋表面下方的位置。 在一个方面,BOP可以单独部署到海洋中,然后随后与LMRP和/或MLP / LMRP组合的设备包配合在海底。

    • A valve assembly suitable for use as an inlet metering valve of a fuel injection system comprises an inlet opening, an outlet aperture, and a valve element arranged to control fluid flow between the inlet opening and the outlet aperture. The valve element is moveable in response to an applied control signal to a closed position and to a fully-open position, and is biased to return to a rest position when the control signal is absent. When the valve element is in the rest position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively low rate. When the valve element is in the closed position, fluid flow between the inlet opening and the outlet aperture is substantially prevented. When the valve element is in the fully-open position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively high rate.
    • 适合用作燃料喷射系统的入口计量阀的阀组件包括入口开口,出口孔和被布置成控制入口开口和出口孔之间的流体流动的阀元件。 阀元件可以响应于施加的控制信号而运动到关闭位置和完全打开位置,并且当控制信号不存在时被偏置回到静止位置。 当阀元件处于静止位置时,入口开口和出口孔之间的流体允许以相对低的速率流动。 当阀元件处于关闭位置时,基本上防止了入口和出口孔之间的流体流动。 当阀元件处于完全打开位置时,入口开口和出口孔之间的流体允许以相对高的速率流动。
