Marine umbilical cable

A marine umbilical cable permitting support of an underwater device and carrying all necessary conduits to the device comprising:

• (a) a wire rope stress member substantially disposed along the axis of the umbilical cable;
• (b) a low melt temperature high strength plastic jacket compression extruded onto the exterior and into the outer interstitial area throughout the length of wire rope;
• (c) an inner polyurethane jacket extruded onto the low melt temperature plastic jacket thereby producing a transitional effect between the substantially incompressible wire rope center and a high strength, highly resilient, low durometer elastomer disposed contiguous to the exterior surface of the polyurethane jacket;
• (d) a high strength, highly resilient, low durometer elastomer material extruded onto the inner polyurethane jacket thereby providing a shock absorber effect against radial forces on the umbilical;
• (e) conventional elements helically cabled around the elastomer of (d);
• (f) a resilient fill material injected during the cabling process into the interstices formed between the exterior surface of the high strength, highly resilient, low durometer elastomer material of (d) and the surfaces of the helically cabled elements;
• and
• (g) an external jacket extruded therearound thereby permitting easy removal of the exterior jacket, repair or replacement of the helically cabled elements.

A marine umbilical cable permitting support of an underwater device and carrying all the necessary conduits to the device comprising:

• (a) an aramid fiber stress member substantially disposed along the axis of the umbilical cable;
• (b) an inner polyurethane jacket compression extruded onto the stress member in Step (a);
• (c) a high strength, highly resilient, low durometer elastomer material compression extruded onto the inner polyurethane jacket thereby providing a shock absorber effect against radial loads upon the umbilical cable;
• (d) conventional elements helically cabled around the elastomer material of (c);
• and
• (e) an exterior polyurethane jacket tube extruded onto the helically cabled elements.
