Abstract
The disclosed system incorporates an integrated rail power and communication bus system, a superimposed communication signal on a wire pair, inductive couplers for transmission of low power and communication, a redundant multi-master bus system, and a novel multi-material manufacturing method for a power transmission rail system with inductive couplers. The integrated power bus rail may be used on a subsea production system, such as subsea production trees, injection trees, carbon injection trees, manifold and boosting structures and other subsea structures.
