Wireless control systems help prevent hardwired service loop failures for moving equipment

摘要

WIRELESS CONTROL systems offer great potential for modern drilling rigs, but increased reliability and lower costs can only be achieved if changes to industry culture occur. Moving equipment poses a challenge for reliable automation systems. For the types of tools that move along rails or a track, the control cables must trail behind the equipment as it moves along. Often, the most vulnerable links in an automation system are the small conductor wires making up the communication cables and instrument cables in dynamic service loops. As the cables move, they are exposed to tensile forces, torsional stress and mechanical fatigue.
