Installing Subsea Cables

North Sea Link Interconnector Project

This is the third Blog in a series by Nexans explaining how their subsea solutions are helping to meet global demand.

In this video Blog Nexans explain how to install a subsea cable across a mountain lake by building a new cable-laying vessel. The pontoon barge weighs over 300 tons and it carried and installed the cables across the small lake Suldalsvatnet.

Subsea power cables play a key role in the penetration of renewable energies into the transmission grids. They are also important links for islands which can be connected to the main grids to secure their energy supply, in addition to reducing their CO2 emissions by limiting the power generation from thermal power plants.
