Offshore oil and gas platforms operate in some of the harshest environments on Earth and safety remains the top priority for them. With explosive atmospheres and corrosive conditions to extreme temperatures present in these environments, every topside product requires flawless performance, to ensure safety and reliability.


As the industry pushes for greater safety, sustainability, and cost-efficiency, the demand for durable, low-maintenance, and easy-to-install cabling solutions has never been higher.

A legacy of innovation: our RADOX® cable technology


Originally developed over 40 years ago, HUBER+SUHNER RADOX® cable technology has evolved to meet the demanding needs of the oil and gas industry. Designed for harsh environments, RADOX cables offer exceptional reliability and longevity—qualities that are essential for offshore platforms, FPSOs, and refineries.

By reducing maintenance costs and supporting sustainability goals, RADOX cables are helping operators in these industries, to future-proof their infrastructure.


HUBER+SUHNER RADOX® OFL® (Outstanding-Flexible-Lightweight) cables are a game-changer for offshore applications. These cables combine high-performance materials with a compact, lightweight design, offering unmatched durability and efficiency. 


The advanced RADOX cross-linked polymer enables continuous exposure to high temperatures (up to around 145°C in the cable core), far beyond standard cables, enabling the cable with excellent mechanical strength, chemical stability, and durability.

Key benefits at a glance:


Save weight and space:


RADOX OFL cables are up to 60% lighter and more compact than conventional alternatives, leading to structural design savings worth hundreds of thousands of dollars.

Life-time guarantee:


Thanks to electron beam cross-linking, the RADOX OFL sheath resists weathering and mechanical stress, lasting up to 10 times longer than standard offshore cables. No brittle breaks—even after 15-20 years.

Reduced accessory costs:


With RADOX OFL, smaller cable diameters mean smaller, more affordable accessories like glands and trays, reducing both cost and installation complexity.


Highest safety standards:


Fully compliant with DNV-CP0400 and NEK 606 Categories A to C (and partially D), RADOX OFL meets the highest safety standards in the industry.


Sustainability with smarter design


As the oil and gas industry evolves, so does the need for materials that meet future safety, environmental, and operational demands. Even the smallest components can make a big impact. RADOX OFL cables not only enhance safety and reliability but also contribute to the oil and gas industry’s sustainability goals. By reducing material usage, maintenance needs, and carbon footprint, these cables support a more responsible approach to offshore operations.


HUBER+SUHNER’s RADOX OFL cables represent a forward-thinking solution, combining safety, efficiency, and sustainability in one powerful package. Whether you're upgrading existing infrastructure or designing new systems, choosing the right cabling can be a small step with a big impact.
