Faired cable for anchoring offshore structures

Claim 1

A fairing assembly for cables which comprises: (a) a pair of elongate elastomeric, wedge shaped body members each having an essentially planar inner surface, a tapered outer surface connected to one edge of each planar inner surface and extending outwardly therefrom to an elongate flexible web interconnecting said pair of body members at said tapered outer surfaces, and a contoured end wall connected to the edge opposed to said one edge of each planar inner surface and extending to a contoured inner surface provided by the flexible web, one of said body members having at least one shaped projection extending outward from the planar inner surface thereof, the projection progressively increasing in width from the point of connection to the planar surface to a point along the elevation of the projection from the planar surface, then progressively decreasing in width to the apex thereof, the other of said bodies having a receptacle adapted to receive said projection in interlocking relation, the contoured end walls cooperating with the contoured inner surface provided by the web to form an opening having the shape of the cable to be faired when the shaped projection of one of said body members is interlocked with the receptacle of the other body member and each one edge of each planar inner surface, at the edge of connection to the tapered outer surface, being upwardly turned to form a biased compressive seal when said body members are connected in interlocking relation.

Claim 6

A system for continuously fairing cables which comprises: (a) a means for playing a cable to be faired; (b) means for dispensing a fairing body opened about the axis of symmetry thereof, the fairing body being comprised of two interlockable wedge shaped elastomeric body members connected by a flexible web, the said interlockable wedge shaped body members and web laying in an essentially common plane when dispensed; and (c) die means adapted to receive the played out cable and the dispensed opened fairing body, said die means including means to fold the web and wedge shaped body members of the fairing body around the cable and interlock said wedge shaped body members; said die means including knife edge means to open the interlocked fairing body when said cable and fairing body are drawn through said die in a reverse direction.

Claim 7

A system for continuously fairing cables which comprises: (a) a means for playing a cable to be faired; (b) means for dispensing a fairing body opened about the axis of symmetry thereof, the fairing body being comprised of two interlockable wedge shaped elastomeric body members connected by a flexible web, the said interlockable wedge shaped body members and web laying in an essentially common plane when dispensed; and (c) die means adapted to receive the played out cable and the dispensed opened fairing body, said die means including means to fold the web and wedge shaped body members of the fairing body around the cable and interlock said wedge shaped body members; said die means including knife edge means to open the interlocked fairing body when said cable and fairing body are drawn through said die in a reverse direction.
