EXPERIMENTAL INVESTIGATION OF TOWING FORCES FOR CARGO SHIPS IN ICE

Three methods for ice cruising by cargo ships are in use: independent travel by the cargo ship; cargo ships traveling behind an icebreaker; and ships escorted by towing close up. An analysis of fleet operations in the Arctic shows that the third method, towing ships close behind icebreakers, is the most promising. It is explained that existing towing gear, however, have several drawbacks, and that new, reliable and efficient towing gear are therefore urgently needed. Their development requires a better understanding of the magnitude of the forces developed in close-up towing, and special studies carried out for this purpose are discussed. They involved inertial tests on a high-powered icebreaker and tandem icebreaker/ship tests, as well as strain gage measurements in the frame members of the icebreaker's stern cutout.
