Airgun umbilicals

Umbilicals for offshore oil and gas exploration and research

Safe and reliable deployment, equipment durability and transfer of both pressurised energy and signal are all critical elements to successful seismic operations for airgun umbilical operations. Fibron undertook an in-depth study of our Airgun Umbilical designs to meet the needs of modern-day standards.

Increasing performance

This study included choice of extrusion materials, component lay angles, and other proprietary detailed design and manufacturing solutions that improve product performance in this harsh environment.

These 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.

ARMOURED LEAD-IN/TOW CABLES

Cables for multiple streamer towing applications

In 2001 Fibron was approached by a major seismic contractor to develop the next generation of armoured Lead-In cable with the aim to reduce 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%.

Design improvements for the seismic industry

This was a substantial improvement upon the existing design, and which had a real impact on the performance of the vessel, by reducing the overall in water drag characteristics, resulting in lower fuel consumption; and allowing operation in shallower waters, as the cable catenary is considerably less. In addition, seismic vessels need to tow many streamers, to be as efficient as possible, and this is a key differentiator for efficient collection of high-quality seismic data and operational efficiency such as fuel consumption. This requires wide tow angles and higher towing forces, putting additional strain on the Lead-In cable.

Fibron’s product has survived very well in these arduous conditions, and with hundreds of kilometres of this cable deployed, Fibron’s Armoured Lead-In Cable product is now the standard design and sets the global standard for lead-in cables.
