摘要： A running tool for use in the insertion of an object such as a casing hanger into a subsea well includes a body and a hollow mandrel moveable within the body. Engagement dogs are supported within the body and are moveable to engage the object, the mandrel having a first part and a transition part, the transition part being shaped to cause out-ward movement of the dogs when the mandrel is in a given position within the body and to allow movement of the dogs for position of the mandrel spaced form the given position. The tool has an emergency release feature wherein the transition part is releasably attached to the first part by shear pins which shear in response to a sufficient increase in pressure within the mandrel to allow the transition part to separate from the first part.

摘要： A hydraulic valve comprises a plurality of ports, which communicate with a passageway, and a valve member movable in the passageway to control the communication between the ports. The valve member carries a lateral shear seal which is integral with the valve member and engages the passageway. In one position, the valve member isolates a first port from a second port. In another position of the valve member, the shear seal communicates with the first port and provides communication between the first port and the second port by way of a passage within the valve member. The valve member has first and second portions of different effective cross-section areas and on each portion an integral sealing member makes a radial seal between the valve member and the passageway. A supply port supplies pressure to the outside of the valve member so as to produce by virtue of the different cross-sectional areas a force tending to move the valve member towards a closed position.

摘要： A device for the application of a preload between a subsea wellhead and a conductor housing comprises an activating member (1), a support housing (2), a locking member (3), end means (9) for securing the support housing relative to the well-head. Movement of the activating member causes an inclined lateral movement of the locking member. The activating member carries a ratchet (7) comprising a multiplicity of serrations which have a regular pitch in the activating direction and the support housing (1, 2) cames at least two latches (19, 20) which allow the relative movement and can engage the ratchet to inhibit movement reverse to the activating direction. The discrete locking positions provided by one of the latches are positionally out of phase with the discrete locking positions provided by the other latch or latches. A support member (16) is positioned to be moved laterally in response to movement of the activating member and to support the locking member (3) against the engagement zone (18) of the datum member (2).

摘要： In a token bus system a node with the token can transmit on the bus a packet that contains two destination addresses. One address specifies the node that should receive the data component (payload) of the transmitted packet. The other address specifies the node that should receive the token. The network protocol specifies that a node with the token must immediately transmit a packet containing just the token or a packet with token and data if it has data to send. When no data is being passed from one node to another on the network, the token may be passed from one node to the next in order. Each node will pass the token to the next highest node number. If a node has the token has some data for sending it transmits a packet with the token for the next node and data for any of the nodes. The bus system requires every node to receive all packets and process them to determine whether the token or the data (or both) is destined for that node.
摘要翻译：在令牌总线系统中，具有令牌的节点可以在总线上传送包含两个目的地址的数据包。一个地址指定应该接收所发送的数据包的数据组件（有效载荷）的节点。另一个地址指定应该接收令牌的节点。网络协议指定具有令牌的节点必须立即发送包含令牌的数据包或具有令牌和数据的数据包，如果它具有要发送的数据。当网络上没有数据从一个节点传递到另一个节点时，令牌可以按顺序从一个节点传递到下一个节点。每个节点将令牌传递到下一个最高节点号。如果节点具有令牌具有用于发送的一些数据，则发送具有用于下一个节点的令牌的分组以及用于任何节点的数据。总线系统要求每个节点接收所有数据包，并处理它们以确定令牌或数据（或两者）是否发往该节点。

摘要： A cap for a subsea tree having a re-entry hub (1) and for use with a tubing hanger (25) deployed within the tree comprises an outer sleeve (3) for fitment over the hub and an inner sleeve (19) adapted to extend within the hub. The sleeve has communication couplers (27, 37) for cooperation with the tubing hanger. Preferably the communication couplers are located at the extremity of the inner sleeve. The couplers can accommodate dummy plugs or live couplers to suit the mode of application. The inner sleeve (19) supports at least one annular seal (21, 22) which provides a barrier between the inner sleeve and the inner periphery of the hub. The outer sleeve (19) includes releasable engagement fittings (16) for securing the outer sleeve to the hub. The cap is adapted for use as a running tool.
