Title:
SHAPE OF ENERGY CONSERVATION TYPE HIGH SPEED VESSEL
Document Type and Number:
Japanese Patent JP2020059479
Kind Code:
A
Abstract:
To provide a vessel attaining both wave resistance reduction and securing of restitution force in a vessel form having a vessel side shape with recesses applied to the vessel side in a high speed vessel with a Froude number of a function expressing vessel speed at 0.32 or more.SOLUTION: A vessel with a Froude number of 0.32 or more is characterized by a vessel form in a vessel side shape having recesses so that no recesses exist in a portion of an arc shape bilge plate by: obtaining propulsion performance improvement by reducing the draining amount to be less than that in a normal vessel form along a length of 1/3 of a between-perpendiculars length Lpp between an SS6 position and an SS3 position from a fore perpendicular; applying the maximum recess amount on a full-load water line LWL at an SS4 position and a 1/2 position in a central range of a hull along a length of 1/3 of the between-perpendiculars length Lpp; forming a recessed shape reducing the recess amount in a curved shape between the SS6 position and the SS3 position from the fore perpendicular; eliminating the recess amount in the SS6 position and the SS3 position; and reducing the recess amount as progressing downward than the recess amount at the full-load water line LWL.SELECTED DRAWING: Figure 10
