Abstract
A tool joint assist system includes one or more iron roughnecks for making up or breaking out tubular joints; a programmable logic controller for each of the one or more iron roughnecks; at least one camera associated with each of the one or more iron roughnecks; a computer that calculates a stick-up height; and one or more user-input devices. Each programmable logic controller controls only one iron roughneck. The computer includes a processor, memory, and one or more monitors displaying an image from the at least one camera. The programmable logic controllers, the cameras, the monitors, the user-input devices, and the computer are connected by a network.
Claims16
A tool joint assist system comprising:
- one or more iron roughnecks for making up or breaking out tubular joints;
- a programmable logic controller for each of the one or more iron roughnecks, each programmable logic controller controlling only one iron roughneck;
- at least one camera associated with each of the one or more iron roughnecks;
- a computer that calculates a stick-up height, the computer comprising:
- a processor;
- memory;
- one or more monitors displaying an image from the at least one camera;
- and
- one or more user-input devices,
- wherein the programmable logic controllers, the cameras, the monitors, the user-input devices, and the computer are connected by a network.
A positioning method comprising:
- capturing a two-dimensional image of a first object to be manipulated by a second object;
- displaying the captured two-dimensional image of the first object combined with an aiming line overlay;
- adjusting a location of the aiming line overlay relative to the first object in the captured two-dimensional image according to user input;
- calculating a parameter of the first object from the adjusted location of the aiming line overlay;
- sending the parameter to a control system for the second object;
- and
- setting a position of the second object by the control system based on the parameter of the first object.
