Abstract

1373140 Icebreaking cargo vessel EXXON RESEARCH & ENG CO 19 June 1972 [7 July 1971] 28500/72 Headings B7A and B7S In an icebreaking vessel having a downbreaking bow 13 and a cargo-carrying section 19, 20 the maximum ice-waterline beam of the hull is located in the bow and the ice-waterline aft of this has a relatively smaller beam aft of the midpoint of the hull. The portion of the hull below the ice-waterline has a maximum beam located in the aft part of the vessel and this maximum beam is greater than the maximum ice-waterline beam. Vertical sections through the hull in the forward portions of the vessel to a predetermined section aft are such that the hull slopes downwards and inwards and the hull aft of the predetermined section, including the stern, slopes downwards and outwards. The vessel has greater manoevrability, greater displacement, greater icebreaking facility and greater rudder and screw protection against it when proceeding astern in ice.
