Baltic Subsea Cable Repaired

;s Cinia said on Friday its C-Lion1 submarine telecoms cable between Finland and Germany, which was suspected to have been damaged in January, had been repaired.Cinia suspected the damage had occurred in the early hours on January 26 in the same area where damage was detected in another subsea fibre optic cable linking Sweden and Latvia."The cable fault was minor and communications through the cable worked normally," Cinia said in a statement.The Baltic Sea region is on alert and the NATO alliance has boosted its presence after a series of power cable, telecom and gas pipeline outages

Tampnet to Help Enable Remote Ops at Woodside’s Trion FPU

Tampnet, a Norway-based provider of offshore connectivity services, has secured a fibre optic project and long-term service contract for fibre connectivity at Woodside’s Trion deepwater field in the Gulf of Mexico.The fibre-based connectivity to shore for Trion will enable remote operations, safety and training capabilities which will be managed from a Woodside onshore facility based locally in Mexico.  The additional subsea fibre cable of approximately 200km represents a significant addition to Tampnet’s existing fibre infrastructure in the deepwater region of the Gulf of Mexico

Turbidity Currents and Their Effects on Subsea Fibre Optic Cables

When sediment becomes suspended within a mass of water, this increase in density causes the water body to begin moving downslope under the influence of gravity. This is termed a turbidity current. These high-energy currents can form through several different processes but three of the most common are offshore of rivers during flooding events, where large amounts of sediment are carried out to sea and then begin to move down the continental slope following volcanic eruptions such as Tonga as the eruption column collapses and during landslides caused by earthquakes, where the finer sediment thrown up by

Another Baltic Undersea Cable Damaged

An undersea fibre optic cable between Latvia and Sweden was damaged on Sunday, likely as a result of external influence, Latvia said, triggering an investigation by local and NATO maritime forces in the Baltic Sea."We have determined that there is most likely external damage and that it is significant," Latvian Prime Minister Evika Silina told reporters following an extraordinary government meeting.Latvia is coordinating with NATO and the countries of the Baltic Sea region to clarify the circumstances, she said separately in a post on X.Latvia's navy earlier on Sunday said it had dispatche

Sweden Seeks Return of Chinese Ship Linked to Baltic Sea Subsea Cable Sabotage

Sweden is asking a Chinese vessel to return to Swedish waters to help facilitate the Nordic country's investigation into recent breaches of undersea fibre-optic cables in the Baltic Sea, Prime Minister Ulf Kristersson said on Tuesday.Two subsea cables, one linking Finland and Germany and the other connecting Sweden to Lithuania, were damaged in less than 24 hours on Nov. 17-18, raising suspicions of sabotage, countries and companies involved said.Denmark's military said soon afterwards that its vessels were staying close to Chinese bulk carrier Yi Peng 3, which travelled through the Baltic Sea

I also don't want to believe in versions that these were ship anchors that accidentally caused the damage," German Defence Minister Boris Pistorius said before a meeting with EU colleagues in Brussels.Two fibre-optic cables - one linking Finland and Germany, the other connecting Sweden to Lithuania - stopped working between Sunday and Monday, recalling previous security incidents in the busy waterway affected by war between Russia and Ukraine."We have to state, without knowing specifically who it came
