At 1706 on 29 April 2011, the Panama registered bulk carrier Dumun grounded while departing the port of Gladstone, Queensland. Prior to the grounding, the ship’s steering appeared to stop responding to bridge commands when the linkage between the tiller and rudder angle transmitter became detached. The steering gear continued to operate normally, but the transmitter lost its input signal and, as a result, the bridge mounted rudder angle indicator stopped working.
