Box shaped bilge keel

a box-shaped bilge keel technology, applied in the field of floating vessels, can solve the problems of reducing the heave and pitch motion of the plate, the plate cannot provide only limited stability to the floating vessel, and the plate does not have any impact on the reduction of the heave and pitch motion, so as to achieve more damping and reduce the pitch motion considerably

Abstract

A box shaped bilge keel comprises a convex polygonal shaped cross-section. Further, the box shaped bilge keel extends along a pre-determined length of a hull of a floating vessel. Also, the box shaped bilge keel is providing additional width to the hull at the bottom of the floating vessel.

Description

FIELD OF THE INVENTION

[0001] Embodiments of the present invention relate to floating vessels and more particularly to a box shaped bilge keel for the floating vessels.BACKGROUND ART

[0002] Dynamic motions for floating vessels such as FSRUs (Floating Storage Regasification Units) are important design considerations during initial stages of design. Dynamic motions such as heave, roll and pitch motions introduce additional loads on hull structure and operational restrictions during the loading / offloading of cargo. Also, higher dynamic motions affect crew operability and comfort. Bilge keels are usually employed at sides of the floating vessels to reduce tendency of the floating vessels to roll.

[0003] Generally, bilge keels are in the form of a ‘strake’ or ‘plate’ on the sides of the floating vessels. Some of the bilge keel designs have been discussed below:

[0004] U.S. Pat. No. 6,176,191B1 discloses bilge keels for an FPSO type petroleum production system. The bilge keels have two lines of p...
