Climate change and global warming will drastically impact daily life in the coming years and make it possible to work, travel, and safely extract and transport raw materials in the Arctic.
Recent US Geological Survey studies estimate that the Arctic accounts for about 13% of undiscovered oil, 30% of undiscovered natural gas, and 20% of undiscovered liquefied natural gas. Alaska-based mining is a $1 billion dollar business (largely from zinc), while Canada produces half a billion dollars of zinc, gold, lead, silver and iron ore.
A new Canadian mining project will build 150 km of railways and two new ports to access some $23 billion worth of iron ore 300 miles inside the Arctic Circle. Meanwhile, Northwest Russia continues to mine 25% of the world’s known minerals in hundreds of deposits.
The Arctic is currently the source of 10% of the world’s oil production and 25% of its gas production, with Russia alone producing 80% of its oil and 90% of its gas in high northern latitudes. Already, hundreds of oil and gas production sites are operating offshore and onshore in the North American and Eurasian Arctic regions.
ICEFLEX Cable from Nexans
The Far North contains 22% of the world’s undiscovered recoverable resources. Dozens of geographical sectors are now being prospected in the Mackenzie Delta−Beaufort Sea Basin, the Sverdrup Basin and the Barents Sea (e.g. the vast Shtokman field).
Once new resources are found, special technologies will be needed to adapt to Arctic conditions to assure safe and secure production, both off and onshore, and ensure environmental safety.
Accessibility to resources via northern shipping lanes requires a new generation of tankers, containerships, LNG carriers, deep-sea drilling and FPSO ships, supply ships, prospect and scientific vessels and even cruise ships for tourism. Also, oil & gas and mining needs rolling stock and port facilities which can function safely and reliably under extreme cold conditions.

A Cable For All Seasons, Conditions & Applications
As a ship designer, engineer, shipyard, installer, or offshore/onshore refinery, you want high-performance marine cables that will:
meet the challenge of severe cold, storms and iceberg threats
operate reliably in icy, snowy conditions for a variety of technical applications
survive in exposed conditions onboard, topside or in frozen ground or permafrost
adapt to abrupt temperature variations during the Spring and Autumn period
safeguard the Arctic environment from chemical and biological threats
protect crew, platform workers and personnel from fire, smoke and dangerous gases
assure higher productivity and competitiveness in tough conditions
support all exploration, extraction, refining and transportation activities
provide sustainable new technologies for the economic viability of Arctic projects
Meet The Arctic Challenge
The Nexans Research Center has already developed various rubber-based cable products to operate at very low temperatures for shipbuilding, offshore, rolling stock, and wind turbine applications.
Understanding and mastering the factors determining the low-temperature resistance of halogen-free flame retardant rubbers was the key to success.
To meet the Arctic challenge, Nexans introduced the innovative ICEFLEX technology for ultra-cold cables. This is the first marine energy cable on the market qualified for use at -50°C. Normally cables become stiff and brittle in intense cold. However, this rubber-based cable remains highly flexible and resistant, while ensuring advanced fire performance.
ICEFLEX ultra cold cable meets the Arctic Challenge
ICEFLEX operates reliably in icy, snowy conditions for a variety of technical applications. It can survive in exposed conditions onboard, topside or in frozen ground or permafrost, and can adapt to abrupt temperature changes during the spring and autumn period, while protecting crew, platform workers and personnel from fire, smoke and corrosive gases.
The ability to comply with impact and bending tests at very low temperature, to withstand the aggression of chemical substances (from gear, hydraulic fluids to mineral oils) and not propagate fire are other outstanding achievements.
ICEFLEX will ensure that resources are extracted and transported safely to assure the sustainable development of the Arctic North. Nexans has already helped ice-protect the Prirazlomnaya stationary oil platform in the Barents Sea with ICEFLEX.
ICEFLEX for shipbuilding & offshore/onshore
Nexans new ultra-cold-resistant rubber cable was designed for all shipboard and offshore/onshore applications. Not only can it maintain its properties down to -65°C, it is also fire-retardant and resists oils and aggressive chemicals and fluids.
The ability to withstand these environmental constraints is a major technical achievement which will make it easier to safely develop new oil and gas fields, shipping routes and refineries in the High Arctic.
ICEFLEX HFFR cable
Halogen-Free Flame & Fire Retardant (HFFR) cable is widely specified in shipbuilding and the oil and gas industry.
This product is fully certified by RMRS and is now commercially available to shipyards and refinery builders worldwide.
Benefits of Nexans ICEFLEX ultra-cold cable
flexibility and high mobility is maintained down to -65°C and more for the life cycle of the cable
EPR hydrocarbon rubber insulation combines unique electrical performance with mechanical toughness and resistance to atmospheric agents (ozone, UV, heat, etc.)
EVA elastomer in the outer sheath resists the deteriorating influence of oils, chemicals, heat and extreme weather aggression
fire-retardancy: the cables do not propagate smoke, fire, or generate toxic gases for personnel, and corrosive gases which can damage equipment
fire-resistance: they maintain power supply for vital safety equipment (emergency lighting, alarm systems, fire pumps, communication circuits, etc.)
high impact-resistance at ultra-cold conditions, meaning that they will neither crack nor break when subjected to sustained or violent physical shock (vibration, operational stress, iceberg impact)
safety and security for all exploration, extraction, refining and transportation activities

Arc Flash
Two companies have been fined after a worker received serious electrical burns caused by an arc flash during demolition work.
Chelmsford Magistrates Court heard how on April 12 2017, two demolition workers employed by sub-contractor R B Haigh & Sons were removing electrical distribution equipment from a switchgear room at the former Molecular Products site in Thaxted, Essex.
Alan Banks had been told by the principal contractor that the electrical equipment had been isolated. To reassure his colleague that it was safe he threw a crowbar at the 400V ac equipment.
This came into contact with live exposed wires, causing a flashover and temperatures of several thousand degrees, followed by a subsequent fire.
As a result Banks suffered serious burn injuries and was immediately hospitalised.
An HSE investigation found that the task being undertaken had not been properly planned and suitable control measures were not implemented to ensure the isolation of the electrical power supply.
The principal contractor, A J Wadhams & Co Ltd failed to follow the clear procedures outlined in their risk assessments and method statements, which identified all equipment must be treated as live unless written authorisation proved otherwise.
Russell Haigh and Stuart Haigh (Partners of R B Haighs & Sons) of Thaxted, Essex, pleaded guilty to safety breaches and were fined £80,000 and ordered to pay costs of £3882.65.
AJ Wadhams & Co Limited trading as Wadham Homes of London also pleaded guilty to safety breaches and was fined £80,000 and ordered to pay costs of £3816.60.
After the hearing HSE inspector Adam Hills said “This incident has had a significant impact on Mr Banks life and the injuries could so very easily have been fatal.
“Had the companies followed the control measures outlined in their respective risk assessments, then this incident would not have occurred.
“Never assume that an electrical supply is disconnected. Always check with the Distribution Network Operator or a qualified electrician to obtain written proof of isolation before commencing work.”
ARC FLASH STATISTICS
30,000 Arc flash incidents per year
7,000 Burn injuries per year
2,000 Hospitalisations per year
400 Fatalities per year

Developed in the 1970’s by 3M, Cold Shrink technology has been found to be a safer, more reliable and easier to install technology for the jointing, terminating and abandoning of low voltage power cables.
Helping MV HV Contractors Make The Change
In order to help cable contractors, cable jointers and engineers make the change out of heat shrink and into 3M Cold Shrink, we feature a YouTube Video Playlist covering the installation of cable joints, terminations and abandonment kits using 3M Cold Shrink.
Cables must be jointed and terminated accurately, safely and quickly – T&D & 3M can provide cable jointer training to further reduce the risk of cable failure caused by poor workmanship.
5 Good Reasons To Switch From Heat Shrink To 3M Cold Shrink
Reduced danger of damaging XLPE cable material – no scorching
Less room for cable jointer error – no skill-sensitive multiple layer heat shrinking, single part construction
No special site permits required – cold applied joints/terminations, no “hot-working”
No cooling time needed before power energising – reduced outage periods and downtime
