Sweden Investigates Damage to Baltic Sea Cable: Cause Remains Uncertain

Introduction
The Swedish Accident Investigation Authority (SHK) recently released a report regarding the damage sustained by the C-Lion 1 subsea cable in the Baltic Sea on November 18, 2024. The findings conclude that authorities are unable to determine whether the damage was caused by an accident or deliberate action.

Investigation Details
The incident drew attention to the Chinese bulk carrier, Yi Peng 3, which was initially linked to the cable damage. Investigators from Sweden and several neighboring countries boarded the vessel as part of the inquiry. However, the SHK noted that access to crucial evidence, including surveillance footage and the ship's Voyage Data Recorder, was restricted. Furthermore, interviews with the crew were conducted in the presence of Chinese officials, which raised concerns about the availability and integrity of the information collected.

Scenarios Considered
In their report, the SHK outlined two main possibilities regarding the cable's damage. The first scenario suggests that the vessel's anchor may have been intentionally released to harm the subsea infrastructure. The second scenario proposes that the anchor detached due to inadequate security measures on the ship. Although the report emphasized that the absence of damage to key anchor components makes the accidental scenario less probable, the investigation faced limitations in confirming either hypothesis definitively.

Maritime Law and Compliance
Under international maritime law, investigations into incidents occurring in international waters are typically led by the flag state of the vessel. However, the SHK’s report highlighted that exceptions can apply in cases where suspected criminal activity is involved, complicating the investigation into this incident.

Concerns Over Potential Sabotage
While some analysts have speculated about the possibility of state-sponsored sabotage, officials from various European nations have started to express a greater confidence that the recent incidents involving cable breaks are unlikely to be the result of coordinated or intentional actions.

Conclusion
The uncertainty surrounding the cause of the damage to the Baltic Sea cable reflects the challenges of investigating incidents that occur in international waters. As authorities continue to evaluate the circumstances, discussions about the implications for subsea infrastructure and cybersecurity remain a critical area of concern.
