Embodiment 1

[0039] This embodiment provides a bow for increasing the capacity of a cargo tank, wherein: figure 2 Schematic diagram of the bow structure for increasing the cargo tank capacity provided by the present invention; image 3 The side view of the bow for improving the capacity of the cargo tank provided by the present invention; Figure 4 The lateral cross-sectional view of the bow for increasing the cargo tank capacity provided by the present invention; Figure 5 for image 3 A-A view in the middle. Such as Figure 2~5 As shown, the bow for increasing the capacity of the cargo tank includes the bow hull 1 and the front bulkhead 2 of the cargo tank. Among them, the design waterline half-width H of the bow hull 1 at the front bulkhead 2 of the cargo tank is 30%-50% of the hull half-width H0, and the position of the front bulkhead 2 of the cargo tank reaches 92%-95% from the stern perpendicular The position between the vertical lines.

Embodiment 2

[0043] This embodiment provides a bow with improved cargo tank capacity. Such as Figure 2~5 As shown, the bow for increasing the capacity of the cargo tank includes the bow hull 1 and the front bulkhead 2 of the cargo tank. Among them, the design waterline half-width H of the bow hull 1 at the front bulkhead 2 of the cargo tank is 30%-50% of the hull half-width H0, and the position of the front bulkhead 2 of the cargo tank reaches 92%-95% from the stern perpendicular The position between the vertical lines.

[0044] Further, the bow of the vessel to increase the cargo tank capacity also includes the bulbous bow 4. Specifically, the line connecting the front edge of the bow hull 1 is a flat line, which is parallel to the height direction of the hull, and the front end of the bulbous bow 4 is located on the rear side of the flat line.

[0045] In this embodiment, the line connecting the front edge of the bow hull 1 is a straight line, and the straight line is parallel to the heig...

Embodiment 3

[0047] This embodiment provides a bow for increasing the capacity of the cargo tank, such as Figure 2~5 As shown, the bow for increasing the capacity of the cargo tank includes the bow hull 1 and the front bulkhead 2 of the cargo tank. Among them, the design waterline half-width H of the bow hull 1 at the front bulkhead 2 of the cargo tank is 30%-50% of the hull half-width H0, and the position of the front bulkhead 2 of the cargo tank reaches 92%-95% from the stern perpendicular The position between the vertical lines.

[0048] Further, the bow of the vessel to increase the cargo tank capacity also includes the bulbous bow 4. Specifically, the line connecting the front edge of the bow hull 1 is a flat line, which is parallel to the height direction of the hull, and the front end of the bulbous bow 4 is located on the rear side of the flat line.

[0049] Furthermore, the bulbous bow 4 is wrapped inside the bow hull 1.

[0050] In this embodiment, since the bulbous bow 4 is wrapped...

Abstract

The invention provides a prow for improving the capacity of a liquid cargo tank, and relates to the technical field of ship construction and repair. The prow for improving the capacity of the liquid cargo tank includes a prow shell and a bulkhead at the front end of the liquid cargo tank; the prow shell is located at the portion, wherein the half width H of a designed waterline is 30-50% of the half width H0 of a ship body, of the bulkhead at the front end of the liquid cargo tank; the bulkhead at the front end of the liquid cargo tank reaches the position which is 92-95% away from an after-perpendicular line. According to the prow for improving the capacity of the liquid cargo tank, the half width of the designed waterline is designed to be large, the bulkhead at the front end of the liquid cargo tank thus can move forward, the cross section of the liquid cargo tank at the position of the prow is increased, the utilization rate of a first-part linear space is improved, and the arrangement of the liquid cargo tank is optimized, so that the capacity of the liquid cargo tank can be largely increased. On this basis, the invention also provides a liquefied gas ship.

Description

Technical field [0001] The invention relates to the technical field of ship construction and repair, in particular to a bow and a liquefied gas ship with improved liquid cargo tank capacity. Background technique [0002] The cargo tank capacity of a super-large liquefied gas ship is a very critical indicator for ship design, but the layout of the cargo tank is closely related to the line type, especially the first line design, especially the design of the waterline to the tank layout and the hull. Fast performance is a contradiction. [0003] For super-large liquefied gas ships with medium speed (Fourde’s number is about 0.185), the existing bow line is usually made by making the front part of the design waterline thinner, and then designing with a certain length of the ball The wave making of the bow of the hull is optimized. However, such a design is not very beneficial to the layout of the first cargo tank, especially for ship types that currently need to meet the latest IGC c...
