SUBSEA COMMUNICATIONS MULTIPLEXER
First Claim
1. A system for communicating between a surface facility and a subsea production control system, comprising:
- a communications device proximate the water surface, the water surface communications device having at least one communication interface;
a communications device functionally associated with the subsea production control system proximate the water bottom, the water bottom communications device having at least one communication interface;
a communication channel extending between the surface communication device and the water bottom communication device;
a multiplexer functionally coupled to the communication interface of each of the water bottom and water surface communication devices;
at least two remote devices functionally coupled to the water bottom multiplexer, the devices comprising at least one of a sensor and a control; and
at least two corresponding devices coupled to the surface multiplexer, the at least two corresponding devices comprising at least one of a signal acquisition device and a control signal generating device.

Abstract
A system for communicating between a surface facility and a subsea production control system includes a communications device proximate the water surface. The water surface communications device has at least one communication interface. A communications device is functionally associated with a wellhead or subsea structure proximate the water bottom. The water bottom communications device has at least one communication interface. A communication channel extends between the surface communication device and the water bottom communication device. A multiplexer is functionally coupled to the communication interface on each of the surface and water bottom communication devices. At least two remote devices are functionally coupled to the water bottom multiplexer. The remote devices comprise at least one of a sensor and a control. At least two corresponding devices are coupled to the surface multiplexer. The corresponding devices include at least one of a signal acquisition device and a control signal generating device.
