Communication life line 60m Supercon 4F, DK termination

The JH TEKNIK High-Tensile Subsea Communication Lifeline is an elite, dual-purpose diving umbilical accessory engineered for heavy-duty commercial diving, saturation diving, and specialized marine rescue operations. This 60-meter product seamlessly integrates a high-break-strength KEVLAR load-bearing safety core (Lifeline) with a high-fidelity, shielded 4-conductor voice communication cable. Encased inside a robust, seawater-resistant, anti-hydrolysis polyurethane (PU) outer protective jacket and terminated with a military-grade SUPERCON 4F circular subsea female connector, the cable utilizes proprietary Danish DK molded termination technology (DK termination) to ensure uncompromised physical safety and crystal-clear, zero-latency voice transmission across extreme underwater dragging, high-current environments, and heavy abrasive conditions.

  • Integrated 2-in-1 Safety Lifeline & Comm Cable: Features a built-in KEVLAR structural strength member delivering exceptional break-strength ratings that exceed standard commercial diving lifeline regulations.
  • Military-Grade SUPERCON 4F Connector: Equipped with a heavy-duty, wet-mateable SUPERCON 4-pin female subsea connector to ensure exceptional corrosion resistance and high-integrity gas-tight sealing. 
  • Molded DK Termination Process: Features JH TEKNIK's proprietary Danish-standard DK molded strain-relief boot, eliminating the risk of water ingress or wire core breakage during extreme underwater pulling forces.

Scope of Application

  • Heavy pulling commercial diving tasks, marine hull scrubbing, propeller repairs, and marine salvage operations
  • Tactical fire department rescue diving, marine police evidence recovery, and search operations in low-visibility shipwrecks
  • Routine subsea offshore structural maintenance aboard offshore rigs, offshore oil platforms, and offshore wind turbines
  • Military diver tactical voice links, subsea underwater probe cables, and emergency subsea towing operations

Double Security for Voice and Life Safety: JH TEKNIK 60M High-Tensile Comm-Lifeline Umbilical (10247D)

  • Search & Rescue Diver Retrieval: Empowers surface tenders to locate, pull, and guide emergency rescue divers in zero-visibility, high-current currents.
  • Offshore Wind Array Foundations: Endures high-velocity subsea currents and friction, maintaining stable, long-distance communication links for offshore diving engineers.
  • Subsea Metal Cutting Operations: Withstands abrasive contacts against jagged ship wreckage plates and welding debris.

Value&Benefits

The JH TEKNIK 10247D Communication Lifeline is the ultimate double-shield for underwater operations. When subsea divers experience emergency air loss or sudden physical distress, this 60-meter umbilical ceases to be a mere voice wire—it serves as an armored physical lifeline engineered to bear hundreds of kilograms of tensile load to haul the operator safely back to the surface.

  • Simplified Diving Logistics: Combines safety rope and communication wire into a single cable, eliminating dangerous subsea umbilical twisting and tangles.
  • Outstanding Wear Durability: Highly resilient polyurethane jacket tolerates barnacle abrasions and welding heat sparks, lowering fleet consumption budgets.
  • Electrostatic Interference Shielding: Fully shielded internal twisted pairs block electromagnetic noises generated by subsea generators and pumps.

Performance

  • KEVLAR core supports outstanding working loads and high ultimate tensile strength limits during emergencies.
  • Wet-mateable female connector features self-aligning grooves for quick, worry-free blind mate connection under thick diving gloves.
  • Maintains high flexibility across both warm tropical waters and sub-zero Arctic sea temperatures without stiffening.

Specifications

  • Cable Length: Standard 60 meters (Approx. 196 ft)
  • Terminal Connector: SUPERCON 4F (4-pin circular underwater wet-mateable female connector)
  • Termination Style: Genuine Danish-style DK molded termination with integrated heavy-duty strain relief boot
  • Product Code: 10247D
  • Conductor Layout: 4-core high-purity Oxygen-Free Copper shielded conductor (2 twisted pairs supporting full-duplex audio and micro-video)
  • Outer Sheath: Heavy-gauge, marine-grade, chemical-resistant Polyurethane (PU) jacket

Certifications

  • Fully compliant with IMCA (International Marine Contractors Association) diving lifeline and communication load-bearing regulations
  • Fully compliant with OSHA commercial diving safety standards for offshore applications
  • CE marked and tested for continuous subsea salt-spray and marine environmental resistance

Maintenance

  • Wash cable jacket and SUPERCON terminals thoroughly with warm fresh water after each deployment to prevent salt crystal damage.
  • Apply specialized subsea silicone grease to the SUPERCON 4F contact sockets regularly to maintain water-tight isolation.
  • Coil the cable using large-radius bends (minimum 15x cable diameter) to prevent shielding wire fatigue and KEVLAR structural strain.
