Abstract
Abstract A buoyant electric cable has a core member such as a pipe for supporting a plurality of elements which are stranded around the core member. Some of said elements are electric conductors and the other elements are tubes which are adapted to receive a fluid for changing the buoyancy of the cable. An eccentric foamed jacket surrounds the stranded elements with a sensing element embedded in the thickest part of the jacket. A protective jacket is preferably provided over the outside of the foamed jacket.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
69 words
A buoyant electric cable comprising an elongated hollow member; said member including a core member, a plurality of elements of substantially equal diameters stranded around said core member in a single layer to form a stranded structure having a substantially uniform outer diameter, some of said elements being electric conductors, and the remainder of said elements being tubes, and a foamed jacket lighter than water surrounding said stranded structure.
Claim 2
Dependent Claim
69 words
A buoyant electric cable comprising an elongated hollow member; said member including a core member, a plurality of elements of substantially equal diameters stranded around said core member in a single layer to form a stranded structure having a substantially uniform outer diameter, some of said elements being electric conductors, and the remainder of said elements being tubes, and a foamed jacket lighter than water surrounding said stranded structure.
Claim 3
Dependent Claim
75 words
A buoyant electric cable comprising an elongated hollow member; said member including a core member, a plurality of elements stranded around said core member to form a stranded structure, some of said elements being electric conductors, and the other of said elements being tubes, and a foamed jacket lighter than water surrounding said stranded structure, said foamed jacket being of different thickness around its periphery with the maximum thickness being diametrically opposite the minimum thickness.
Claim 4
Dependent Claim
75 words
A buoyant electric cable comprising an elongated hollow member; said member including a core member, a plurality of elements stranded around said core member to form a stranded structure, some of said elements being electric conductors, and the other of said elements being tubes, and a foamed jacket lighter than water surrounding said stranded structure, said foamed jacket being of different thickness around its periphery with the maximum thickness being diametrically opposite the minimum thickness.
Claim 5
Dependent Claim
17 words
A buoyant electric cable according to claim 2 including a protective outer jackeT surrounding said foamed jacket.
Claim 6
Dependent Claim
16 words
A buoyant electric cable according to claim 2 in which said core member is a pipe.
Claim 7
Dependent Claim
37 words
A buoyant electric cable according to claim 4 in which said pipe is made of polyethylene and said foamed jacket is made of foamed polyethylene, and said cable including a protective outer jacket surrounding said foamed jacket.
Claim 8
Dependent Claim
22 words
A buoyant electric cable according to claim 5 including a sensing device enclosed in the maximum thickness portion of said foamed jacket.
Claim 9
Dependent Claim
93 words
A buoyant electric cable comprising an elongated hollow member; said member including a first pipe comprising a core member, a plurality of elements stranded around said core member to form a stranded structure, some of said elements being electric conductors, and the other of said elements being tubes, a foamed jacket lighter than water surrounding said stranded structure, a second pipe within said first pipe having an outside diameter less than the inside diameter of said first pipe so as to provide a space therebetween, and a strength member within said second pipe.
Claim 10
Dependent Claim
93 words
A buoyant electric cable comprising an elongated hollow member; said member including a first pipe comprising a core member, a plurality of elements stranded around said core member to form a stranded structure, some of said elements being electric conductors, and the other of said elements being tubes, a foamed jacket lighter than water surrounding said stranded structure, a second pipe within said first pipe having an outside diameter less than the inside diameter of said first pipe so as to provide a space therebetween, and a strength member within said second pipe.
Claim 11
Dependent Claim
17 words

Claim 12
Dependent Claim
17 words
A buoyant electric cable according to claim 8 including a sensing device enclosed in said foamed jacket.
Claim 13
Dependent Claim
23 words
A buoyant electric cable according to claim 9 in which said strength member is a torque balanced steel rope encased in a jacket.
Claim 14
Dependent Claim
30 words
A buoyant electric cable according to claim 1 in which said foamed jacket is of different thickness around its periphery with the maximum thickness being diametrically opposite the minimum thickness.
Claim 15
Dependent Claim
22 words
