Abstract: Techniques for identifying and locating a fault within a subsea hydrocarbon extraction system include receiving, via a main channel line and from a first subsea modem, first data associated with a first subsea control module, wherein the main channel line is communicatively coupled to the first subsea modem via a first channel leg line, receiving, via the main channel line and from a second subsea modem, second data associated with a second subsea control module, wherein the main channel line is communicatively coupled to the second subsea modem via a second channel leg line, identifying a fault or a developing fault in the first channel leg line based on an analysis of the first data and the second data, and generating and transmitting a notification indicating the fault or the developing fault in the first channel leg line.

Abstract: A method of detecting a correct position and/or orientation of a secondary winding structure of a secondary unit relative to a primary winding structure of a primary unit of a system for inductive power transfer to a vehicle, wherein the vehicle includes the secondary unit for receiving an alternating electromagnetic field which is generated by the primary unit, wherein the vehicle includes at least a first transmitter for transmitting a first signal and a second transmitter for transmitting a second signal, wherein a wayside control unit includes at least one receiving means for receiving the first and the second signal, and wherein the correct position and/or orientation of the secondary winding structure of the secondary unit relative to the primary winding structure of the primary unit is detected depending on the first and the second signal.
