Montenegro: Terna contractors Nexans and Prysmian placed first underwater cable connection Italy-Balkans

, SEE Energy News

Norwegian Nexans, partner of Italian Terna, laid the first 140 km of the first of two underwater electrical cables from Pescara to Montenegro.The process of protecting cable is underway, performed according to standard procedures in order not to damage the various risk factors. This is the first part of the cable whose setting up began on February 27th, and about what have reported Montenegrin media.

By this was ended the first phase of the cable installation, the project worth about 800 MEUR. The Norwegian boat set up cable within 20 days. As said those who are familiar with the situation, the cable was embarked on a special boat in one piece, also owned by Norwegian company. The cable is placed on the boat as large ball that is slowly unwound and laid in the water through a special device that resembles of a crane.

It remains Norwegians to make and set a difference for a total of 393 km of submarine cable, or about 250 km. Two pieces of cable are connected by special, sophisticated methods.

Another cable will work and set the Italian Prysmian, also partner of Terna in this business. The Italian company, the largest in the world in its sector, will begin to realize its part of the work for about a year.

Two cables will be about 500 m away from each other.If you did not know, and you probably did not, the cable has a diameter of only 13 cm! However, only one meter weighs less than 43 kg!

As we were covering earlier, it is a highly specific work, in the sense that the factories do not keep in stock its product, but the ordered cable length is produced and delivered strictly to order.

Length of cable that connects two banks is 393 km under the sea, and it is a total of 415 km. The difference of 22 km is set to the mainland – by 16 miles in Italy and six per cable in Montenegro.

It is, therefore, the total length of two cables of 830 km.

Treaty on establishing the submarine interconnection between Montenegro and Italy was signed on November 23rd, 2010th, between the Government of Montenegro, Montenegrin Electric Transmission System (CGES) and the Italian company Terna. The contract stipulates that, during 40 years from cable construction, the revenues will be divided in such a way that Terna belongs 80 percent, and 20 percent to the Montenegrin transmission system. CGES participates in the cable construction with 20 percent, provided that the bulk of funds are provided through credit arrangements with the German Development Bank and the European Bank for Reconstruction and Development.
