Abstract
The present disclosure relates generally to data communication in subsea oil and gas drilling and production operations. In particular, data communication from sensors located on a piece of subsea oil and gas drilling and/or production equipment to a remote location, such as to a demodulation system, is disclosed. The data communication system can include sensors for measuring various characteristics of the subsea equipment, for coding the measured data into a signal, for transmitting the signal, and for ultimately decoding the signal. The signal is transmitted along the structures which provide the containment for existing hydraulic fluid lines associated with the subsea equipment by a variety of methods, such as by pulse position modulation and/or reverse time pulse position modulation. The communication system can further include a local power generator assembly to power associated sensors and transmitters.
