    摘要: The present invention describes a valve actuator having a first motor (30) for moving a valve element and a second motor (30′) for energizing a failsafe spring (130). The second motor is operated independently from the first, thus allowing the valve element to be moved between its open and closed positions while the spring is energized. In an emergency, the spring will be de-energized and move the valve element to its failsafe position no matter the position of the valve element.

    摘要: The invention relates to a control system for a subsea installation based on CAN bus technology. A single cable forms a backbone for transmitting signals and/or power from a central control unit to a number of devices or sensors on the installation. Terminals are attached to the cable at intervals, allowing devices to be plugged in while the system is operable. A termination may also include repeaters or amplifiers for transmitting signals over longer distances.

    摘要: The invention is a well radar for detecting, by electromagnetic wave reflection, resistivity horizons in production zones in oil wells. Transmitter and receiver antennas are combined in a tubing string antenna module. Two dipole transmitter antenna are positioned in a first position on either side of the tubing string antenna module. A first directionally sensitive group of four dipole receiver antennas is positioned in a second positioned so that the receiver antennas have even angular separation. Likewise, a second directionally sensitive group of four dipole receiver antennas is positioned in a third position opposite the first directionally sensitive group.
