Finnish Court Sentences Russian Captain and Crewman to Prison for Subsea Cable Sabotage

A Finnish court has sentenced the Russian captain and an Azerbaijani crew member of a commercial cargo ship to prison for deliberately sabotaging undersea telecommunications cables. The landmark ruling marks one of the first times a civilian crew has faced criminal liability for destroying critical maritime infrastructure, setting a new legal precedent for European security.[1][4]

The Helsinki District Court convicted 57-year-old Andrei Maksimenko and 48-year-old Vusal Majidov of aggravated criminal damage on Thursday. The three-judge panel unanimously found that the men intentionally dragged their vessel's heavy anchor across the Gulf of Finland seabed on New Year's Eve in 2025, dismissing claims that the destruction was merely a navigational accident.[2][3]

Maksimenko, who served as the ship's captain, received a prison sentence of three years and six months. Majidov, the vessel's boatswain, was sentenced to two years and 10 months. Both men were ordered to be taken into custody immediately directly from the courtroom following the reading of the verdict.[3][5]

The court also imposed significant financial penalties on the convicted sailors to cover the massive repair bills. The men were ordered to jointly pay approximately €1.9 million ($2.1 million) in damages to the affected companies, while Maksimenko must pay an additional €85,000 individually for his role in the incident.[2][5]

A 130-kilometer trail of destruction

The incident centered on the Fitburg, a 132-meter general cargo vessel sailing under the flag of Saint Vincent and the Grenadines. The ship departed the Russian port of St. Petersburg on December 30, 2025, carrying a heavy load of steel products bound for the Mediterranean port of Haifa, Israel.[2][5]

According to Finnish investigators, the ship's anchor and its locking mechanism were in proper working order and fully secured when it left the Russian port. However, the court established that the anchor was lowered into the water at some point before the vessel exited Russian territorial waters, beginning a destructive path.[3][5]

The Fitburg dragged its anchor chain and shank for approximately 130 kilometers (81 miles) over several hours. The heavy equipment plowed a deep trench through the Gulf of Finland, directly severing two subsea telecommunications cables operated by the Finnish company Elisa, which connect Helsinki to Tallinn, Estonia.[4][5]

The damage could have been substantially worse, according to the court's detailed findings. The dragging anchor crossed up to nine other telecommunications and electricity cables, as well as a major subsea gas pipeline, putting critical regional energy and communications infrastructure at severe risk of catastrophic rupture.[3][5]

Finnish authorities eventually detected the seabed anomaly and urgently contacted the vessel on the morning of December 31. The court noted that the crew only raised the anchor after receiving these explicit warnings from local maritime officials, prompting the immediate interception and seizure of the ship in the gulf.[2][5]

Establishing intent and jurisdiction

During the eight-day trial held between September and October, prosecutors did not present evidence proving that Maksimenko explicitly ordered the anchor to be dropped, or that Majidov physically lowered it. Instead, the prosecution argued that the men's failure to intervene constituted a deliberate and calculated act of sabotage.[3][5]

The judges agreed with this assessment, ruling that both experienced mariners must have known the anchor was dragging while the vessel continued its voyage. The court concluded that Maksimenko accepted the ship's continued movement, while Majidov actively contributed to its passage despite the obvious drag on the vessel.[2][5]

The court determined that the actions deliberately endangered infrastructure essential to society and that the limited damage resulted from chance. Judges justified the captain's longer sentence by citing his ultimate legal responsibility for the vessel's safe navigation and daily operations.[3]

Defense lawyers fiercely contested the charges, arguing that Finland lacked the legal authority to try the case at all. They pointed out that the physical damage to the telecommunications cables occurred in international waters, strictly outside of Finland's sovereign maritime territory and exclusive economic zone.[2][5]

The district court rejected that jurisdictional challenge entirely. The panel ruled that because the severed cables connected directly to Finland and disrupted vital services there, the intentional offenses had immediate consequences within Finnish borders, giving Helsinki the absolute right to prosecute the perpetrators.[3][5]

Both men have maintained their innocence throughout the lengthy proceedings, which saw them confined to Finland under strict travel bans for nearly a year. Maksimenko's defense attorney confirmed that the captain will appeal the verdict, while Majidov's legal team stated he has not yet decided on his next steps.[2][4]

The Baltic infrastructure threat

The convictions arrive during a period of heightened anxiety over the severe vulnerability of Europe's underwater networks. Since Russia launched its full-scale invasion of Ukraine in February 2022, Western intelligence agencies have repeatedly warned about Moscow's growing capacity and willingness to conduct hybrid maritime warfare.[4][5]

The Baltic Sea, a shallow and heavily trafficked body of water bordered by eight NATO member states and Russia, contains a dense web of data cables and energy pipelines. Unexplained ruptures have become increasingly common, forcing regional navies to intensify their patrols and monitoring operations.[2][5]

In December 2024, Finnish authorities investigated a remarkably similar incident involving the Russian-linked oil tanker Eagle S. That vessel was suspected of damaging power and data links by dragging its anchor, but a Finnish court dismissed the case last October after prosecutors failed to definitively prove deliberate intent.[3][5]

The Fitburg ruling represents a sharp departure from that earlier precedent. By establishing that a crew's failure to notice or correct a dragging anchor can constitute intentional sabotage, the Helsinki court has significantly lowered the threshold for prosecuting suspected hybrid attacks carried out by ostensibly commercial vessels.[2][3]

"Finland has intensified efforts to protect its undersea infrastructure following a string of incidents affecting cables and pipelines in the Baltic Sea since 2022," Reuters noted. The outlet highlighted a recent vessel-boarding drill conducted by Finnish maritime forces in September to prepare for exactly this type of threat.[5]

Sanctions and the shadow fleet

The initial seizure of the Fitburg also highlighted the complex enforcement of European economic restrictions. When Finnish officials detained the vessel at the port of Kantvik, they discovered its cargo consisted entirely of Russian steel products that are subject to strict European Union sanctions.[2][5]

Despite the clear embargo, Finnish customs authorities declined to launch a separate criminal investigation into the cargo. Officials determined that the sanctioned steel only entered Finnish territorial waters because maritime authorities had explicitly ordered the ship to dock there following the cable incident, negating any smuggling charges.[2]

The ship's diverse crew further complicated the initial investigation and diplomatic fallout. The 14 sailors aboard the Fitburg included nationals from Russia, Georgia, Kazakhstan, and Azerbaijan, reflecting the multinational labor pools commonly used in global commercial shipping to obscure direct state involvement.[2][4]

While Maksimenko and Majidov faced serious charges, the remaining crew members were eventually cleared of direct involvement and allowed to leave. The Fitburg itself, which had been held as material evidence and diplomatic leverage, was subsequently released by Finnish authorities earlier this year.[2][5]

The case underscores the immense difficulty of securing critical infrastructure against deniable, low-cost threats. Commercial ships, often sailing under flags of convenience like Saint Vincent and the Grenadines, can inflict massive economic damage using standard equipment, leaving investigators to untangle genuine accidents from state-sponsored sabotage.[2][5]

As the appeals process begins, the broader maritime industry will be watching the outcome closely. The final ruling in the Finnish appellate courts will likely shape how coastal nations police their exclusive economic zones and how shipping companies manage their crews in highly contested waters.[4][5]
