Benefits of technology

This patent describes a system and method for coupling electrical power underground in a subsea distribution system. The system includes a modular circuit breaker assembly controlled by a control system with multiple circuit breaker controls. This means that each circuit breaker can be controlled by multiple control units, even if one control unit fails. The system also has extendable electrical connectors to easily connect different parts of the system. The technical effect of this invention is to provide a more reliable and flexible system for distributing electrical power underwater.

Problems solved by technology

Subsea pumping and processing system are particularly suited for challenging environments, such as the deep sea and Arctic, which are difficult to support from fixed platforms or floating production units.
Such systems are complicated and expensive.

Abstract

A system and method for coupling electrical power subsea. The system comprises a subsea penetrator to seal an opening around a conductor extending through a partition or enclosure. The subsea penetrator comprises an integral current sensor operable to produce a signal representative of current through the conductor. The penetrator comprises a boot configured to seal the opening through which the conductor extends. The current sensor may be disposed within the boot.
