    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 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 present invention regards a joint for use in a riser (1) extending between a floating installation (3) and a subsea installation (2). The joint comprises an inner pipe segment (21) and an outer pipe segments (22), arranged moveable relative each other in an axial direction and connectable to respective riser segments, forming a chamber (23) between them with a radially extending piston (24), dividing the chamber (23) in a first chamber part (25) and a second chamber part (26), wherein on of said chamber parts (25) in an initial position of the joint is adapted to contain a mainly incompressible fluid, this chamber part (25) decreasing in volume as the inner pipe segment (21) is moved relatively out of the outer pipe segment (22). According to the invention the joint is configured with a fluid line connection (30) from said one chamber part (25) to the other chamber part (26), configured such that the relative movement of the pipe segments (21, 22) is controlled by the allowed flow rate of a fluid flowing out of the chamber part (25) through the fluid line connection (30) to the other chamber part (26).
