Amber Cable is a next‑generation Baltic Sea subsea system that will connect Finland, Estonia, Latvia, Lithuania, Poland and Denmark. It will incorporate Distributed Acoustic Sensing (DAS) concepts to enable monitoring and protection of the subsea infrastructure.
The Amber Cable in the Baltic Sea is set to be 1,500km long, with nine cable landing stations in Finland, Estonia, Latvia, Lithuania, Poland, and Denmark. The project is currently in Phase 1, which involves conducting studies and stakeholder engagement. After this follow Phase 2 (FEED – Front-End Engineering Design – and permitting progression), Phase 3 (Technical planning and implementation preparation) and Phase 4 (Deployment and operational readiness).
Amber Cable SIA is a Latvia-based company developing next-generation subsea infrastructure for the Baltic region. In a LinkedIn comment, CEO Simon Fletcher said: "... the Baltic has become the place where resilience is no longer theoretical. The incidents over the last couple of years have shown how quickly exposure becomes operational reality, and why diversified routes matter. From our side, the long‑term picture is where the real work sits. Building the route is one thing; sustaining it over its life is where the operational burden lands — and that depends on people, capability, and the finite marine resources." you’ve highlighted. It’s a valuable point, and one we need to factor into our long‑term operational planning as the Baltic’s resilience profile shifts."
Between December 2024 and January 2025, five Baltic Sea subsea cables were cut. Authorities at first suspected deliberate sabotage by Russia and China, but subsequent investigations have been inconclusive – the cuts may have been accidental.
