Citation:
"In heavy weather a floating dock, which was in tow of two tugs, broke away. Repeated efforts by the tugs to take her in tow again failed, and the dock was drifting rapidly towards the rocks nearby.
Captain Kalkman realised the danger of the situation. With great skill he brought his tug alongside the dock, made fast his lines and then towed her clear of danger. In the very bad weather conditions obtaining, high qualities of courage and leadership were required, and but for Captain Kalkman's action, the dock would have been lost."
