Abstract
A system and method for coupling electrical power subsea. The system comprises a subsea electrical distribution system having at least one modular subsea circuit breaker assembly. The modular subsea circuit breaker assembly may be coupled to sources of power and/or subsea loads via one or more subsea power cable harness assemblies. The modular subsea circuit breaker assembly has at least electrical connector. Each subsea power cable harness assembly has a corresponding electrical connector. At least one of these electrical connectors is extendable to engage an electrical connector opposite it.
Claims18
A modular subsea electrical distribution system, comprising:
- a subsea electrical circuit breaker assembly comprising a first circuit breaker, a frame, a first electrical connector secured to the frame and electrically coupled to a first side of the first circuit breaker;
- and
- a first power cable harness assembly, comprising a frame, a second electrical connector secured to the frame, and a first power cable connected to the second electrical connector and supported by the frame,
- wherein the first electrical connector and/or the second electrical connector is extendable relative to the frame to which it is secured to enable the first electrical connector and the second electrical connector to connect to each other, electrically coupling the first power cable to the first side of the first circuit breaker.
