Embodiment Construction

[0028] exist figure 1 Icebreaking ships are identified with reference numeral 1 in . The icebreaking vessel 1 comprises a hull with a bottom 2 , a bow 3 and a stern 4 . The bow 3 includes a forward-leaning upper bow 31, a lower bulbous bow 33 with a bulbous root section 34, and an intermediate bow 32 between the forward-leaning upper bow 31 and the lower bulbous bow 33, Wherein the bulbous root section 34 is located at a given position S1 of the lower bulbous bow in the length direction of the ship. The icebreaking ship 1 is designed with a structural waterline W1, an upper icebreaking waterline W3 and a lower icebreaking waterline W2. figure 2 is a three-dimensional diagram of the bow 3 above.

Abstract

The present invention relates to an icebreaking vessel, which includes a hull with a bottom (2), a bow part (3) and a stern part (4). The bow part (3) includes a forward inclined upper bow portion (31), a bulbous lower bow portion (33), and an intermediate bow portion (32). The vessel is designed with a construction water line (W1), an upper ice water line (W3) and a lower ice water line (W2). In order to improve the icebreaking capacity of the vessel, an upper surface of the bulbous lower bow portion (33) is arranged to be at or in the vicinity of the water surface when the vessel operates at the construction water line (W1) of the vessel. When the vessel operates at the lower ice water line (W2), a lower surface of the bulbous lower bow portion (33) is arranged to penetrate the water surface. When the vessel operates at the upper ice water line (W3), the forward inclined upper bow portion (31) is arranged to penetrate the water surface. The present invention also relates to a method for operating the icebreaking vessel.

Description

technical field [0001] The invention relates to an icebreaking vessel operating in a body of water having a water surface at sea level according to the preamble of claim 1, the vessel comprising a hull with a bottom, a bow and a stern, wherein the bow comprises a front A leaning upper bow, a lower bulbous bow and an intermediate bow between the forward leaning upper bow and the lower bulbous bow, the lower bulbous bow having a bulbous nose at a given position along the length of the vessel Root section, the icebreaking ship is designed with a structural waterline, an upper icebreaking waterline and a lower icebreaking waterline. The invention also relates to a method for operating an icebreaking vessel according to the preamble of claim 8 . Background technique [0002] For sea-going vessels it is known to reduce drag and thus reduce power requirements and fuel consumption by installing spherical bodies at the bow of the vessel, the so-called bulbous bow. A properly design...
