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.
Claims20
An apparatus comprising:
- a power source at a stationary side;
- an electrical power cable extending from the stationary side to a moveable well construction apparatus;
- a first processing system at the moveable well construction apparatus and comprising a processor and a memory including computer program code, wherein the first processing system is operable to transmit a first message;
- and
- a second processing system at the stationary side and comprising a processor and a memory including computer program code, wherein the second processing system is operable to:
- receive the first message from the first processing system;
- receive a second message input through an input device of the second processing system;
- permit the electrical power cable to be electrically coupled to the power source when the first message and the second message are authorized;
- and
- prohibit the electrical power cable from being electrically coupled to the power source when at least one of the first message and the second message is not authorized.
A method comprising:
- receiving a first message as user input at a first processing system, wherein the first processing system is at a moveable well construction apparatus and comprises a processor and a memory including computer program code;
- transmitting the first message from the first processing system;
- receiving the first message at a second processing system, wherein the second processing system is at a stationary side and comprises a processor and a memory including computer program code;
- receiving a second message as user input at the second processing system;
- permitting, by the second processing system, an electrical power cable to be electrically coupled to a power source at the stationary side when the first message and the second message are authorized;
- and
- prohibiting, by the second processing system, the electrical power cable from being electrically coupled to the power source when at least one of the first message and the second message is not authorized.
