Abstract
A method for controlling propulsion of a drilling rig. The drilling rig includes a right propulsion unit and a left propulsion unit and mutually independent speed control and a transmission for driving the right propulsion unit and the left propulsion unit. The transmission provides at least two gear states of a gear box. A propulsion speed is request for the right propulsion unit and for the left propulsion unit. A difference is determined between a requested propulsion speed of the right propulsion unit and the left propulsion unit. A suitable gear state is determined based on the determined difference. Also a computer program product including program code for a computer for implementing the method. A system and a drilling rig equipped with the system.
