System for communicating data via fluid lines
First Claim
1. A system comprising:
- a plurality of pieces of subsea equipment capable of fluid communication with a plurality of fluid pressurized lines;
a plurality of sensors, each sensor coupled to a respective piece of subsea equipment of the plurality of pieces of subsea equipment and configured to measure a respective characteristic of the respective piece of subsea equipment;
a plurality of transmitters each coupled to a first portion of a respective structure that provides containment for a respective pressurized fluid line of the plurality of pressurized fluid lines and are each configured to transmit the respective measured characteristic from the respective sensor via a respective signal along the respective structure that provides containment for the respective pressurized fluid line of the plurality of pressurized fluid lines; and
a plurality of receivers each coupled to a second portion of the respective structure that provides containment for the respective pressurized fluid line of the plurality of pressurized fluid lines and are each configured to receive the respective signal transmitted along the respective structure that provides containment for the respective pressurized fluid line of the plurality of pressurized fluid lines.

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.
