Nexans supplies cable worldwide and will also install from Terminal to Terminal whenever this is required or more conve-nient for the customer.

The cable may be loaded onto the cable ship at Nexans factory in Rognan, Norway or transported to the cable ship on a freighter.

We have a large team of engineers and project managers who have comprehen-sive experience in both managing large submarine projects and installing subma-rine cables. The engineering resources have modern and sophistica ted tools available for planning and modelling tasks and these have been used in energy, telecom, oil & gas and wind farm projects.

Nexans operates a large vessel to install cables and also has a large suite of containerized equipment that can be used on board a ship-of-opportunity anywhere in the world.

We also work very close with other marine installers in order to provide the most efficient service to our customers.

The marine installation work provided by Nexans includes marine surveys, route engine ering, burial assessment, route clearance, installation, burial, testing, etc.

Summary of Nexans’ submarine cable design:

Nexans Submarine Cables URC-1 and ROC-1

Cable coreThe cable core comprises a central, hermetically sealed steel tube with three different diameters to hold different fibre counts. In addition, the cables can be supplied with two different copper con-ductor solutions - one for electro ding pur-poses and one for power feeding subsea equipment. A polyethylene sheath covers the steel tube and copper conductor.

2.7 mm steel tube for up to 16 fibres3.7 mm steel tube for up to 48 fibres5.6 mm steel tube for up to 96 fibres

The two largest tubes can be equipped with a 7 ohm/km copper conductor, while the smallest tube can be equipped with a 1.4 ohm/km copper conductor.

The sheathing has a diameter of 10 mm for all core alternatives. The core alterna-tives are illustrated to the right.

In addition, four or eight 3.7 mm tubes can be stranded together to offer a maxi-mum of 192 and 384 fibres per cable.

Outer ProtectionIn order to provide the cable core with mechanical protection against hazards during installation and operation, several different armour packages can be applied over the basic cores, depending on the expected hazards. The armouring alternatives are shown to the right.

If Nexans is responsible for a complete, installed system from Terminal to Terminal or from Beach Joint to Beach Joint, the marine work includes route planning, marine surveys, cable transport, and sub-marine cable installation and burial. In addition, Nexans conducts training cours-es for its customers and contractors when-ever necessary.

Route planning and surveys involve find-ing the best route between any two land-ing points, which is normally not the shortest route, taking into account the restrictions imposed by commercial traffic, the fishing industry, environmental regulations, defence interests, seabed topography and the seabed condition.

Cable may be loaded onto a cable ship or freighter at the Nexans factory in Rognan, Norway, or at a harbour in Europe that has railway tracks. In the lat-ter case, cable is coiled directly onto rail-way cars in Nexans’ factory and subse-quently transported to a suitable port.

C/S Nexans Skagerrak loading a fibre optic submarine cable to be installed together with a high voltage cable

The cable ship used for any installation is chosen according to its capacity, rate, availability, suitability and location. Different ships from various owners have been used to install Nexans submarine cables.

Nexans itself operates c/s Bourbon Skagerrak. This ship is purpose-built for installing power cables but has also been used for telecom cables in several projects. Nexans normally uses ships that are purpose-built for telecom installations and whose size and capacity are suitable for each project.

In some cases, cables are installed on the seabed without burial, but in the majority of projects cables are buried in water depths down to 1000 m. This requires various tools, including water-jetting machines and different ploughs. Nexans provides its own jointers to carry out jointing on various cable ships.
