RADOX OFL儀器電纜滿足極端海上環境

RADOX? OFL Instrumentation cables

New high-tech plastic compounds allow the development of cables that have lighter weight and smaller dimensions while providing better electrical values, withstanding higher ambient temperatures without neglecting the safety aspect.

With its RADOX material, HUBER+SUHNER has developed an electron-beam crosslinked high performance compound that meets these extreme Offshore requirements. This has been approved and certified by classification bodies such as DNV, ABS, BV, CCS and others.

Lowest weight and smallest space requirements

All RADOX cables are fully electron-beam cross-linked for the highest mechanical strength and extreme resistance against mud and weather. Compared to RFOU/BROU, RADOX OFL will reduce the weight up to 65 % (average 50 %), and thus save several tons of weight.

Lowest installation cost

RADOX is proven to require 60 % less stripping time compared to today’s Offshore cables. In addition, its flexibility allows the cable to be run more easily over many hundreds of metres even through difficult passages. Where installations may require many tens of kilometres of cables and hundreds of main and branch lines, this amounts to the saving of many days of installation time.

Reduced cable accessory costs

With the reduction in the diameter of the cable, all cable accessories, such as cable glands, cable trays and cable ladders, which can be extremely expensive for Offshore applications, will be reduced. This provides further benefits in terms of additional savings on cost, weight and space. Additionally, RADOX cables have no problems of cold-flow as no bedding is required.

Lifetime guarantee

All RADOX cables use high-end compounds for sheath and core insulation and are fully electron-beam cross-linked to provide the highest mechanical strength and are extremely resistant against temperature, water, mud and corrosion. The 120 °C sheath and 145 °C cores enhance the lifetime of the cable by a factor of 8 compared to standard 90 °C Offshore cables.

RADOX? OFL Instrumentation cables Oil&Gas, flexible and lightweight

RADOX OFL cables apply to all offshore topside applications with outstanding low Total Cost of Ownership (TCO) in terms of weight, space, lifetime, installation and handling of harsh environmental conditions compared to standard RFOU/BFOU.

Application areas:?

• For fixed and moving application
• Dry, damp or wet locations
• Inside and outside ships, offshore platforms, FPSOs and other industrial equipment
• Resistant against oil, mud and hydraulic oil (NEK606:2016 Cat. a-d)
• -40 °C to + 120 °C continuous operating temperature
• Flame retardant (IEC60332) and Fire resistant (IEC60331)

Highlights:

• Thin wall design to reduce weight between 33 % and 63 %
• Approved by IEC/DNVGL- CP-0400 lightweight class program
• Innovative radiation cross-linked RADOX sheath enhance lifetime by factor 8
• Pairs, triples and quadruples with cross-sections 0.75, 1.5 and 2.5 mm2
• Very flexible even with up to 48 pairs
• Ruggadised high-end PEEK cores for high temperature process applications, e.g. steam bolier.
• NEK606 compliant

The requirements in the offshore market are becoming increasingly demanding in the last years. Improvements are needed to run operations more efficiently and with higher safety. It affects engineering, installation and long-term operations. The lifetime of a product must contribute to a low Total Cost of Ownership (TCO). RADOX OFL cable is the advanced solution to achieve this target.

Below numbers show a recent instrumentation cable package where RADOX OFL was compared with standard RFOU/BFOU (total length 608km). On average RADOX OFL could have reduced the total weight by 47 % in this project and thus save more than USD 5 million in steel structure:?

With new innovative materials and different designs, RADOX OFL cable offers huge benefits, especially safety improvement:?

• No cold-flow issues as no bedding is required, thus single compression cable glands can be used with long-term tightness.
• PEEK is the ideal material for process applications like steam/hot oil heating, steam boiler etc. Instrumentation compartments often have a temperature higher than 80-90 °C, that shortens the lifetime of EPR. The consequence is that brittle insulation will lead to short- circuits or wrongly measured process values.
• Another safety risk for operators is the exposure to hydraulic/gear oil which will be swollen by the outer sheath over time and cause cracks. RADOX OFL cable can handle hydraulic/gear oil very well. In the case of cracks in the sheath material, the inside RADOX PEEK cores can withstand the hydraulic/gear oil, serving as a secondary containment to avoid any incidents.

• Safe in moving applications like offshore cranes or drag chains with up to 1.000.000 cycles
