What is cyber rig in oil and gas industry?

Answer 1

Cyber-Rig is a physical model of a semi-submersible drilling unit. The model has eight rotatable azimuth thrusters, two on each leg. The task in control allocation is to generate the generalized forces (surge, sway, yaw, pitch and roll) the controller specifies with the available control effectors/actuators. As a specified force vector can be generated in several different ways, the secondary objective in control allocation is to minimize some criteria, for instance energy consumption.
