A NOVEL ICEBREAKER CONCEPT

With the new concept the icebreaking process differs considerably from that with conventional icebreakers. The main feature is the flat bottomed bow with a beam greater than that of the ship and with sharp edges at the sides. Curves of ice resistance and power required show the advantages of the new hull form. The results of the model tests in open waters are compared with those of vessels with conventional shapes. Order from NSFI as No. 22357.
