Abstract
Apparatus and methods pertaining to a moveable well construction apparatus to be electrically energized via an electrical power transmission path extending between a stationary power source and the moveable well construction apparatus. The path comprises cables and connectors. A system comprises a detector operable for generating information indicative of whether the path is properly installed. The system permits the path to be electrically energized when the detector-generated information indicates the path is properly installed, and prevents the path from being electrically energized when the detector-generated information indicates the path is not properly installed.
Claims24
An apparatus comprising:
- a stationary side comprising a stationary power source;
- a moveable well construction apparatus to be electrically energized via an electrical power transmission path extending between the stationary power source and the moveable well construction apparatus, the movable well construction apparatus comprising a movable support structure, wherein the electrical power transmission path comprises one or more electrical power cables and one or more electrical connectors;
- a system comprising a detector, wherein the detector is operable for generating information indicative of whether the electrical power transmission path is properly installed between the stationary power source and the moveable well construction apparatus, and wherein the system is operable for:
- permitting the electrical power transmission path to be electrically energized when the detector-generated information is indicative of the electrical power transmission path being properly installed between the stationary power source and the moveable well construction apparatus;
- and
- prohibiting the electrical power transmission path from being electrically energized when the detector-generated information is indicative of the electrical power transmission path not being properly installed between the stationary power source and the moveable well construction apparatus.
