Embodiment Construction

[0059] In the case of different embodiments, the same components below will be designated by the same reference numerals.

[0060] Figures 1 to 7 Each shows a view from the rear to a twin-screw boat, wherein in each figure a different embodiment of an arrangement according to the invention on a twin-screw boat is provided. For clarity, in Figures 1 to 7 The propeller of the ship and the rudder arranged downstream of the propeller of the ship are omitted in the present invention.

[0061] figure 1 A twin-screw boat is shown with a hull 50 provided with an arrangement 100 according to the invention. The arrangement 100 comprises two shaft supports 10 to which the propeller shaft 12 is mounted. The propeller shaft 12 is located at least partially outside the hull 50 . Therefore, the axle bracket 10 is also located outside the hull 50 . The shaft bracket 10 covers and supports the propeller shaft 12 . The hull 50 has a central belly 51 which protrudes downwards. On each s...

Abstract

The invention relates to an arrangement for multi screw vessels, in particular twin screw vessels, with external propeller shafts, as well as to a method for producing such an arrangement. The arrangement according to the invention is in particular suitable for a drive system of an above-mentioned multi screw vessel and to improve the energy efficiency thereof.

Description

technical field [0001] The invention relates to an arrangement for a multi-screw ship, especially a twin-screw ship, with an outer propeller shaft, and a method for producing such an arrangement. The arrangement according to the invention is particularly suitable for the aforementioned drive systems of multi-screw ships and for improving their energy efficiency. Background technique [0002] Various devices are known in the prior art for reducing the drive power requirements of single-screw boats. Reference is made here to EP 2 100 808 A1 by way of example. [0003] In the case of a normal single-screw boat, the propeller shaft of the boat's propeller extends inside the hull of the boat. In the case of these ships, only the end of the propeller shaft protrudes from the hull of the ship, with the marine propeller attached to the protruding end of the propeller shaft. In contrast, several types of boats are equipped as multi-screw boats, ie each have at least two marine pro...
