We demonstrate the multiple modes of tug operation under different conditions of ship work. You will investigate the characteristics of the harbour tugs tractor tugs and the Azimuth stern drive (ASD) tugs. You will learn how to fit tugs out for rescue and salvage. You find tugs where there are higher concentrations of heavy shipping traffic. We explain how to record training in the ship’s logbooks and various river work scenarios. We outline the precautions and guiding principles that can assist a pilot in his decisions and describe the use of aft tug for breasting the ship's stern in place of the spring line as the critical manoeuvre steps.
