Abstract

A system for controlling a subsea device comprises a complimentary set of data communication interfaces operatively coupled to an electronically interrogatable component of a subsea device and a remotely disposed device controller via a power conductor which defined data pathway between the subsea device and the remotely disposed device controller. A data transceiver is operatively coupled to the electronically interrogatable component and the remotely disposed device controller via the complimentary set of data communication interfaces over the power conductor. In configurations, control and/or telemetry or other data may be unidirectionally and/or bidirectionally transmitted between the electronically interrogatable component of a subsea device and a remotely disposed device controller. In configurations, data faults may be monitored in a primary data path and, if a fault detected, control and/or telemetry or other data transmission switched to the power conductor data pathway, manually and/or automatically.

Dependent claims

A method of controlling a subsea device, comprising:

a. establishing a data communication path between an electronically interrogatable component of a subsea device and a separate, remotely disposed device controller that is not part of the subsea device over a power conductor cable operatively coupled to a complimentary set of data communication interfaces, one data communication interface of the set of data communication interfaces operatively in communication with the electronically interrogatable component and the other data communication interface of the set of data communication interfaces operatively in communication with the remotely disposed device controller;
b. providing power to the subsea device over the power conductor cable;
c. using the power conductor cable to provide power to the subsea device;
and
d. detecting a primary data transmission pathway data communication failure;
and
e. after detecting the primary data transmission pathway data communication failure, switching to the data communication path to transmit data between the electronically interrogatable component and the remotely disposed device controller over the power conductor cable via a data transceiver operatively coupled to the subsea device and the electronically interrogatable component via the complimentary set of data communication interfaces.

c. a data transceiver operatively coupled to the electronically interrogatable component and the remotely disposed device controller via the complimentary set of data communication interfaces over the power conductor cable;
d. a data transmission failure sensor configured to detect a data transmission failure in a primary data communications pathway;
and
e. a data path switch operatively in communication with the data transmission failure sensor, the primary data communications pathway, and the data transceiver.
