Abstract
An umbilical connection for use in a hazardous environment like a floating roof storage tank has one or more hydraulic hoses, one or more electrical cables or a combination thereof. Each hydraulic hose has a static dissipative and abrasion resistant covering. Each electrical cable has an abrasion resistant coating. The hoses and cables are bundled and wrapped in a static dissipative and abrasion resistant open mesh sheath or an overbraid to form the umbilical connection.
Claims18
A sheath for a combination of one or more hydraulic hoses and one or more electrical cables that together form an umbilical connection, comprising:
- an open mesh or braid formed from a first plurality of polymeric strands, a second plurality of polymeric strands, and one or more electrically conductive strands, such that said electrically conductive strand or strands extends along the length of the sheath, and wherein the hose(s) and the cable(s) forming the umbilical connection are aligned to form a bundle and such bundle generally defines an outer circumference, and wherein the sheath extends substantially around the outer circumference of the bundle.
An umbilical connection for equipment deployed into a hazardous environment, comprising:
- a combination of one or more hydraulic hoses and one or more electrical cables aligned to form a bundle having a first end for connection to equipment deployed into a hazardous environment;
- and
- a sheath of an open mesh or braid formed from a first plurality of polymeric strands, a second plurality of polymeric strands, and one or more electrically conductive strands, such that said electrically conductive strand or strands extends along the length of the sheath, wherein said sheath is wrapped around the bundle to form the umbilical connection.
