INTRODUCTION
Diver's Umbilical Cable | Commercial Surface Supplied Diving Umbilical
Product Overview
A diver’s umbilical is the critical lifeline for surface supplied commercial divers. The Diver's Umbilical Cable integrates breathing air hose, pneumofathometer line, communication cable, optional video coax and power conductors inside one helically bundled assembly. Also known as surface supplied diving umbilical, this hybrid cable continuously connects divers with topside dive control stations during all underwater missions.
Derul Cable designs and manufactures high-performance commercial diving umbilicals for shallow-water air diving and saturation diving operations. We provide customized 3 part diving umbilical and 4 part diver umbilical configurations to meet global diving contractor standards.
Construction Structure
Our surface supplied diving umbilical adopts spiral twisted layout, the industry standard construction for diving lifeline:
Air supply hose: High-pressure PU hose for diver breathing gas transmission
Pneumo hose (pneumofathometer): For real-time depth monitoring
Shielded communication cable: Clear audio communication between diver and surface supervisor
Optional components: Coaxial video cable, power wires, hot water heating line
High tensile strength member: Kevlar / polyester fiber to bear pulling load, avoid tension damage on hoses and wires
Outer PUR/TPU jacket: Polyether polyurethane sheath, anti-abrasion, saltwater corrosion resistant
Technical Specifications
