Modular cable hang-offs are designed to provide secure termination, stability, and protection for cables in offshore and subsea environments. Their design features are tailored to meet the specific challenges of these demanding applications.  

Features

 • High mechanical strength

Purpose: Withstand significant axial and radial forces caused by cable tension, environmental loads, and thermal expansion.  

Design: Reinforced steel or composite sleeves are used to ensure high load-bearing capacity.  

• Dutch cable protection 

Purpose: Minimize damage to cables during installation and operation.  

Design: Smooth internal surfaces and flexible seals are integrated to prevent abrasion or mechanical damage.  

• Corrosion resistance

Purpose: Ensure long-term durability in marine environments exposed to saltwater, high humidity, and temperature fluctuations.  

Design: Made from corrosion-resistant materials like stainless steel or coated with marine-grade paints.  

• Customizable components

Purpose: Adapt to different cable diameters, configurations, and project-specific requirements.  

Design: Modular structures and adjustable grouting systems allow for flexibility in design and installation.  

• Integrated sealing systems

Purpose: Prevent water ingress and maintain structural integrity in subsea conditions.  

Design: Incorporate elastomeric seals or polyurethane coatings to create a watertight barrier.  

• Fatigue and vibration resistance

Purpose: Mitigate the effects of dynamic loading caused by waves, currents, or cable movement.  

Design: Use of flexible components and damping systems to absorb vibrations and reduce stress. 

Application scope of modular cable hang-off

Modular cable hang-offs are widely used in offshore and subsea industries where cables need to be securely terminated and stabilized.  

• Offshore wind farms

Usage: For securing power export cables and inter-array cables that connect offshore wind turbines to substations or the mainland.  

Advantages: Provide stable, long-term solutions for high-tension cables in dynamic marine environments. 

 • Oil and gas platforms

Usage: Terminate and protect umbilicals, risers, and power cables supplying oil and gas platforms.  

Advantages: Capable of withstanding extreme loads and corrosive conditions.  

• Subsea pipelines

Usage: Secure cables used in subsea pipeline monitoring and control systems.  

Advantages: Offer a permanent, robust connection that resists underwater currents and pressure changes.  

• Floating production systems

Usage: Terminate dynamic cables used in floating production storage and offloading (FPSO) systems or tension leg platforms (TLPs).  

Advantages: Designed to handle dynamic motions and maintain the integrity of cables.  

• Coastal and harbor projects

Usage: Stabilize underwater power cables and communication lines in coastal or harbor installations.  

Advantages: Effective in shallow water environments where external forces are less intense but stability is still essential.  

• Telecommunications

Usage: Secure subsea fiber optic cables in telecom networks.  

Advantages: Provides a reliable solution for protecting and anchoring sensitive communication cables.
