## Abstract

An umbilical for use, for example, in deep water applications includes a plurality of power cables and may include other elements bundled together and within a sheath. An end termination at each of the power cables or at a plurality of the power cables includes a resin ferrule around the cable at the end termination and provides a connection between the cable and an installation to which the umbilical is connected.

## Claims

### Claim 1

An umbilical comprising:
at least one electrical power cable, said power cable comprising a high strength conductor; and
a hang-off termination configured to connect said power cable to an installation, the hang-off termination comprising a ferrule coupled to an end of said power cable said ferrule being coupled to an insulator that is in compression or in tension when said hang-off termination connects said umbilical to said installation.

### Claim 2 (depends on 1)

The umbilical of claim 1, further comprising a plurality of power cables each connected to the hang-off termination.

### Claim 3 (depends on 2)

The umbilical of claim 2, wherein the hang-off termination comprises a respective ferrule on each of the power cables, each ferrule extending around a respective portion of a power cable and each ferrule being operable to provide a support system for the respective conductor.

### Claim 4 (depends on 1)

The umbilical of claim 1, wherein the ferrule is comprised of a resin conglomerate with high compressive strength.

### Claim 5 (depends on 4)

The umbilical of claim 4, further comprising a plurality of power cables each connected to the hang-off termination.

### Claim 6 (depends on 1)

The umbilical of claim 1, further comprising additional elements within and extending through the umbilical, the elements being selected from the group consisting of electrical cables, optical cables, optical fiber cables, pipes, and hoses.

### Claim 7 (depends on 6)

The umbilical of claim 6, wherein the elements extending through and along the umbilical are bundled together; filler material is around the bundled together elements, and an external sheath is disposed over the filler material and the bundled together elements.

### Claim 8 (depends on 1)

The umbilical of claim 1, wherein said ferrule is partially embedded in said insulator and partially resides in a cavity defined by a housing.

### Claim 9 (depends on 1)

The umbilical of claim 1, wherein said ferrule is coupled at one end thereof to a respective end of said insulator, said insulator having an opposite end configured for connection to said installation.

### Claim 10 (depends on 9)

The umbilical of claim 9, further comprising a primary hang-off termination and a rigid frame, said rigid frame extending between and spacing said primary hang-off termination and a hang-off location, said rigid frame being in compression when said insulator is coupled to said hang-off location.

### Claim 11 (depends on 10)

The umbilical of claim 10, wherein said hang-off location comprises a plate.

### Claim 12 (depends on 9)

The umbilical of claim 9, further comprising a wheathershed surrounding said insulator.

### Claim 13 (depends on 1)

The umbilical of claim 1, wherein said ferrule is threadably coupled to said insulator.
