Abstract
The present invention relates to a hull in particular for a container ship, a bulk carrier and a tanker. The hull includes an elevation of an outer contour of the hull with respect to an upwards directed vertical direction of the hull in the region of a first body plan and a second body plan in relation to a surface section immediately adjoining to the elevation. Therein, the elevation is arranged in a region between a middle and a stern of the hull.
Claims18
A hull for a ship comprising:
- an elevation of an outer contour of the hull with respect to an upwards directed vertical direction of the hull in a region of a first body plan and a second body plan in relation to a surface section immediately adjoining to the elevation,
- wherein the elevation is arranged in a region between a middle and a stern of the hull and the elevation is located on a bottom side of the hull,
- wherein the outer contour in the first body plan, which extends in a bow-side region of the elevation, comprises a first inflection point and a second inflection point and the outer contour in the first body plan reaches a maximum value with respect to the vertical direction in a region of a center of the elevation,
- wherein the outer contour in the second body plan, which is located closer to the stern of the hull in relation to the first body plan, comprises a first depression with a third inflection point and a fourth inflection point centrally in the elevation, wherein the first depression is a part of a retaining device for a ship propeller shaft for receiving a ship propeller,
- wherein the outer contour in the second body plan comprises a fifth inflection point and a sixth inflection point, wherein the third inflection point is located farther outwards with respect to the first depression transversely to the hull in relation to the fifth inflection point and the fourth inflection point is located farther outwards with respect to the first depression transversely to the hull in relation to the sixth inflection point,
- wherein the outer contour comprises a seventh inflection point in a longitudinal section of the hull along a preset central line of the elevation in the bow-side region of the elevation and transitions from the elevation into the first depression over an eighth inflection point on a stern-side end of the elevation, and
- wherein a vertical position of the elevation adapts to a vertical position of the surface section adjoining thereto at the stern-side end of the elevation along the longitudinal section in the direction of the stern.

- wherein the outer contour in the second body plan reaches a further maximum value with respect to the vertical direction in the region of the center of the elevation,
- wherein the outer contour comprises a seventh inflection point in a longitudinal section of the hull along a preset central line of the elevation in the bow-side region of the elevation and transitions from the elevation into a stern-side section of the hull over an eighth inflection point on a stern-side end of the elevation, and
- wherein a vertical position of the elevation adapts to a vertical position of the surface section adjoining thereto at the stern-side end of the elevation along the longitudinal section in the direction of the stern.
