TUG DESIGN AND DEVELOPMENT
After a general discussion on the characteristics required in modern ship-handling tugs, including those which handle large floating bodies such as drilling-rigs, the Author (of Schottel-Nederland B.V.) examines how these requirements can be met, in particular with the aid of cycloidal propellers and rudder-propellers. These devices can be installed in the forebody, a position which reduces the chance of girting and has other advantages. The advantages of tractor tugs (tugs with cycloidal propellers or rudder-propellers in this forward position) are then discussed more fully, with particular reference to tugs with Schottel rudder-propellers. In Hamburg, three tug-owners operate, or have on order, 15 Schottel tractor-tugs, with bollard pulls ranging from 27 to 35 tons. Order from: BSRA as No. 47,634.
