Patent number: 8806092Abstract: 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.Type: GrantFiled: February 17, 2005Date of Patent: August 12, 2014Assignee: FMC Kongsberg Subsea ASInventors: John A.

Publication number: 20090127485Abstract: 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.Type: ApplicationFiled: December 27, 2005Publication date: May 21, 2009Applicant: FMC KONGSBERG SUBSEA ASInventors: Jorgen Wessel, Vidar Sten-Halvorsen, Torstein Kasin, John A.
