Abstract: An apparatus for controlling a subsea blowout preventor (BOP) includes a control system for controlling a subsea BOP of a subsea stack assembly installed over a subsea oil and gas well. The control system includes a first topside control device and a second topside control device, and a first subsea control device and a second subsea control device. The first topside control device, the second topside control device, the first subsea control device, and the second subsea control device are each communicatively connected with the BOP and operable to control operation of the BOP. The first subsea control device is a portion of a first control pod of the subsea stack assembly. The second subsea control device is a portion of a second control pod of the subsea stack assembly. The first topside control device is communicatively connected with the second topside control device via a ring communication network.

Abstract: A well construction system having well construction equipment operable to perform well construction operations to drill a well, power equipment operable to supply electrical power to the well construction equipment via an electrical power bus, operational data sources operable to output operational data, and a power manager communicatively connected with the operational data sources and the power equipment. The operational data sources may include sensors associated with at least one of the well construction equipment, the power equipment, and the electrical power bus. The power manager receives the operational data and outputs power control data to the power equipment to control the electrical power being supplied by the power equipment to the well construction equipment via the electrical power bus during the well construction operations based on the operational data.

Abstract: Systems and methods for managing power at a wellsite. A system includes well construction equipment, power equipment, a power manager, power equipment sensors operable to output power equipment sensor data indicative of operational status of the power equipment, and a human-machine interface usable by a human user to enter power management settings. The power manager is operable to receive the power equipment sensor data and receive the power management settings, wherein each power management setting is associated with a corresponding mode of operation of the power manager. The power manager is further operable to, for each power management setting, change the mode of operation of the power manager to the mode of operation associated with that power management setting, and for each mode of operation, cause the power equipment to supply electrical power to the well construction equipment in a predetermined manner with respect to that mode of operation.
