Nord Stream Operators Sue Insurers Over Pipeline Sabotage

other · 2026-04-24

On September 26, 2022, four underwater explosions destroyed the Nord Stream I and II gas pipelines near the Danish island of Bornholm. The pipelines, which run from Russia to Germany, were sabotaged in an act widely attributed to a Ukrainian team. Seven Ukrainians, including four professional divers, are suspected of attaching explosives from a sailing yacht. One suspect was arrested in Italy, extradited to Germany, and is now in pretrial detention in Hamburg. The operators of the pipelines have filed lawsuits against insurers, including Lloyds and Arch, seeking compensation for the damage. The insurers have refused payment, arguing that damage from acts of war is excluded from coverage. The legal question now hinges on whether the sabotage constitutes terrorism, which might be covered, or an act of war, which is not. The case remains unresolved, with no successful claims to date.
