摘要 |
The invention pertains to a method for controlling propulsion of a drilling rig (100), said drilling rig comprising right propulsion means (130b) and left propulsion means (130a) and mutually independent speed control and a transmission (235; 335) for driving said right propulsion means (130b) and left propulsion means (130a), said transmission providing at least two gear states of a gear box (235), comprising the steps of: - requesting propulsion speed for said right propulsion means and for said left propulsion means; - determining (s430) a difference (Diff) between a requested propulsion speed of said right propulsion means and said left propulsion means; - determining (s430) suitable gear state on the basis of the thus determined difference (Diff). The invention also relates to a computer program product comprising program code (P) for a computer (210; 220) for implementing a method according to the invention. The invention also relates to a system and a drilling rig (100) being equipped with said system. |
