The performance specifications for airgun umbilicals and lead-in cables used for offshore data acquisition are becoming increasingly challenging as the amounts of data increase and new technologies like Life of Field, EM and Nodal have emerged.

Fibron is constantly evolving their products to meet the demands of these new technologies to ensure maximum reliability, operational efficiency, and safety. Our experienced team of design engineers and technicians have the knowledge and expertise to design and manufacture umbilicals and cables for these offshore applications.

Key Supplier

As a key supplier to the seismic industry since the early 2000’s, Fibron has developed a unique and extensive portfolio of industry specific products including:

  • Armoured lead-in cables
  • Airgun umbilicals
  • Electromagnetic source umbilicals
  • Deck cables
  • Fairing systems
  • Terminations
  • Tail buoy cables
  • Fibre optical cables
  • Permanent array cables

Armoured Lead-in/Tow Cables

Fibron was approached by a major seismic contractor to develop the next generation of armoured lead-in cable with the aim of reducing the diameter significantly whilst maintaining the required tensile strength and electrical/optical fatigue performance. Using thin wall insulation technology for the electrical cores, steel tube fibre optics, and a high tensile steel armour package, we reduced the diameter by 27%.

This improvement had a real impact on the performance of the vessel by reducing the overall drag characteristics, resulting in lower fuel consumption. It also allowed operation in shallower waters, as the cable catenary is considerably less.

To maximise efficiency, seismic vessels need to tow many streamers with wide tow angles and higher towing forces. This puts additional strain on the lead-in cable. With hundreds of kilometres of this cable deployed, Fibron’s armoured lead-in cable product sets the global standard for lead-in cables.

Airgun Umbilicals

Fibron goes to great lengths to review and improve its airgun umbilical designs. A recent study reviewed the choice of extrusion materials, component lay angles, and other proprietary detailed design and manufacturing solutions that improve product performance in harsh environments.

The resulting improvements have increased product performance and can include a wide range of standard 7/8”, 1” and 1-1/4” aramid reinforced hoses or a selection of multiple high collapse-resistant hose variants.

Electro-Magnetic Source Umbilicals

Fibron has been at the forefront of developing electro-magnetic source umbilical technology.

Working with several customers, we have successfully designed and manufactured a number of umbilicals for use in both deep and shallow water applications. The emphasis has been to provide an umbilical that is capable of supplying high electrical current, whilst achieving a very light-weight design.

Here to help

If you need an umbilical or cable and can’t immediately see what you’re looking for, please do get in touch. Most of our work is bespoke to the needs of a particular project, so we can’t show all of our capabilities on our website. As experts in our field, if you need a cable or umbilical, particularly for use in a challenging environment like offshore, there’s a good chance that we’ll be able to help.
