Abstract
Abstract A hydrodynamic cable fairing section comprising a nose portion for receiving a cable, a trailing body portion, and a plurality of vanes projecting outwardly from the body portion. The body portion includes two side surfaces that extend from the nose portion towards a trailing edge which forms part of the body portion. A plurality of vanes extend on both side surfaces and are substantially parallel to each other. Each of these vanes comprises flat surfaces which taper toward the trailing edge of the body portion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A hydrodynamic cable fairing section comprising a nose portion, a body portion having two side surfaces, and vane means comprising a plurality of vanes connected to each side surface of said body portion, said plurality of vanes being substantially parallel to each other, wherein said nose portion has a continuous curved surface and a longitudinal through bore means for receiving a cable, said body portion extending from said nose portion and tapering from said nose portion towards a trailing edge which forms part of the body portion, and each of said vanes comprises flat surfaces which taper toward said trailing edge of said body portion.
Claim 2
Dependent Claim
105 words
A hydrodynamic cable fairing section comprising a nose portion, a body portion having two side surfaces, and vane means comprising a plurality of vanes connected to each side surface of said body portion, said plurality of vanes being substantially parallel to each other, wherein said nose portion has a continuous curved surface and a longitudinal through bore means for receiving a cable, said body portion extending from said nose portion and tapering from said nose portion towards a trailing edge which forms part of the body portion, and each of said vanes comprises flat surfaces which taper toward said trailing edge of said body portion.
Claim 3
Dependent Claim
20 words
A hydrodynamic cable fairing section according to claim 1 wherein said body portion is integrally formed with said nose portion.
Claim 4
Dependent Claim
32 words
A hydrodynamic cable fairing section according to claim 1 wherein said body portion includes ballast means for enabling the fairing section to rotate with respect to the cable and to vertically align.
Claim 5
Dependent Claim
21 words
A hydrodynamic cable fairing section according to claim 1 including attachment means for attaching said fairing section to adjacent fairing sections.
Claim 6
Dependent Claim
77 words
A hydrodynamic cable fairing section as claimed in claim 1 wherein said vane means further comprise a plurality of pairs of vanes, each of said pairs comprising a first vane connected to one side surface of the body portion, and a second vane connected to the other side surface of the body portion, said first and second vanes positioned in the same plane, and wherein said plurality of pairs of vanes are substantially parallel to each other.
Claim 7
Dependent Claim
39 words
A hydrodynamic cable fairing section as claimed in claim 1 wherein each vane of said plurality of vanes is inclined at an acute angle between 5 and 60 degrees with respect to the longitudinal axis of said body portion.
Claim 8
Dependent Claim
39 words
A hydrodynamic cable fairing section as claimed in claim 1 wherein each vane of said plurality of vanes is inclined at an obtuse angle between 120 and 175 degrees with respect to the longitudinal axis of said body portion.
Claim 9
Dependent Claim
124 words
A hydrodynamic cable fairing comprising a plurality of cable fairing sections and means for interconnecting said cable fairing sections, wherein each of said cable fairing sections comprise a nose portion and a body portion having two side surfaces, and a plurality of vanes connected to each side surface of said body portion, said plurality of vanes being substantially parallel to each other, wherein said nose portion has a continuous curved surface and a longitudinal through bore means for receiving a cable, said body portion extending from said nose portion and tapering from said nose portion towards a trailing edge which forms part of the body portion, and each of said vanes comprises flat surfaces which taper toward said trailing edge of said body portion.
Claim 10
Dependent Claim
124 words
A hydrodynamic cable fairing comprising a plurality of cable fairing sections and means for interconnecting said cable fairing sections, wherein each of said cable fairing sections comprise a nose portion and a body portion having two side surfaces, and a plurality of vanes connected to each side surface of said body portion, said plurality of vanes being substantially parallel to each other, wherein said nose portion has a continuous curved surface and a longitudinal through bore means for receiving a cable, said body portion extending from said nose portion and tapering from said nose portion towards a trailing edge which forms part of the body portion, and each of said vanes comprises flat surfaces which taper toward said trailing edge of said body portion.
