Russia Says Telecoms Cable Damaged Last month Just Before Nearby Baltic Gas Pipeline
A Russian fibre optic cable under the Baltic Sea was damaged last month only 28 km (17 miles) from where a gas pipeline linking Finland and Estonia was damaged soon afterwards, Russian state company Rostelecom said on Tuesday.Finnish police believe damage to the Balticconnector gas pipeline was caused by a Chinese container ship dragging its anchor along the seabed but have not concluded whether this was an accident or a deliberate act.Security of sub-sea cables and pipelines in the Baltic has become a top concern against the background of the Ukraine war, especially since the blowing-up of
Kremlin’s Threat to Interfere with Undersea Data Cables Should Be Taken Seriously
subsea cables are the backbone of the contemporary digital economy. Almost all of our internet connections depend on them.According to SubTelForum’s Submarine Cable Almanac as of the beginning of 2023, there were 380 cables in Europe on the ocean floor, mostly the size of a garden hose. They use fibre optic technology to convey information at large distances.Yet they are easy to cut and get damaged quite frequently. The industry reports up to 100 cable failures annually, mainly caused by fishing activities or the anchors of ships.This rarely causes serious disruptions. As already established above
TenneT Awards Deals for Installation of 7,000 km HVDC Cable System for 10 Projects
current (HVDC) solution based on 525 kV is that it requires only one cable system, and "therefore limits the impact on the environment, on nature and the seabed."The cable system will consist of four cables, a 'plus' and 'minus' pole cable, a metallic return cable, and a fibre optic cable. With twice the size of current connection systems, the new 2 GW standard needs an offshore cable system operating at a 525 kV HVDC voltage level and uses innovative extruded insulation types, TenneT said
Prysmian Bags €1.8B Order to Connect Dutch Offshore Wind Farms
; aggregate value increases the total value of Prysmian’s order book to about €8.5 billion.Prysmian Group will be responsible for the design, engineering, manufacturing, installation, testing and commissioning of two 525 kV HVDC submarine and land cable systems — including fibre optic cables — and all related accessories for the IJmuiden Ver Alpha and Nederwiek 1 offshore wind farms, for a total of 4 GW capacity.©TenneTIJmuiden Ver Alpha is an offshore grid connection system with around 176 km of route length (of which about 164 km offshore), while Nederwiek 1 has
CorPower Ocean, Maersk Supply Service Install Subsea Export Cable for Wave Energy Project in Portugal
Hull Development Programme.The CorPower C4 WEC will later be fused to the cable through a quick-connect interface located at the anchor-head. While providing power connection to feed electricity to shore through the 7.2kV cable it will also deliver high speed communication to the wave farm through fibre optic cores.The CorePower wave energy converters are of the point absorber type, with a heaving buoy on the surface absorbing energy from ocean waves and which is connected to the seabed using a tensioned mooring line. The device oscillates in resonance with the incoming waves, amplifying the motion
Alcatel Submarine Network’s DC/FO Tech together with Equinor ASA wins the 2022 UTC Award
and expanded has been announced as the winner of this year’s Underwater Technology Conference (UTC) Award.Alcatel Submarine Networks’ (ASN) DC/FO subsea power and communications solution combines subsea controls and power in a single, open-standard and standardised high voltage DC and fibre optic cable, reducing the cost and complexities involved in traditional and often more bespoke umbilical cable solutions.The same standard cross section can be used to deliver 100 kW of power over distances in excess of 300 km to any subsea production system supplied equipment. It unlocks new
