First North America’s longest submarine electricity cables arrived

Staff Writer |
The first of North America’s two longest submarine electricity cables has arrived in Atlantic Canada onboard the cable-laying vessel the Skagerrak. The cables each measure 170 km and weigh 5,500 tonnes.

Combined, the two cables weigh more than the Eiffel Tower in France.

The first cable was manufactured in Halden, Norway, while the second cable, which is expected to arrive in mid-May, was manufactured in Futtsu, Japan.

The arrival of the Skagerrak, operated by the cable supplier Nexans, marks the start of the submarine cable installation process.

Over the next few weeks members of Nexans crew will prepare for the installation of the first electrical connection across the Cabot Strait between Nova Scotia and Newfoundland.

Nexans used two facilities for cable manufacturing, allowing both cables to be produced at the same time.

The cable manufactured in Futtsu, Japan, was spooled onto a giant barge in early April and then loaded onto a heavy lift vessel for the long journey to the Cabot Strait to await installation.

The vessel carrying the second submarine cable from Japan will take approximately six weeks to travel to the port in Sydney.

Installation of both submarine cables is expected to be completed.
