Surge in Sanctioned Russian “Shadow Fleet” Vessels Detected Near Irish Waters, Raising Security and Environmental Alarms

Dublin, Ireland – An investigation by The Irish times has revealed a meaningful and concerning increase in the number of sanctioned Russian vessels, commonly referred to as a “shadow fleet,” transiting through or adjacent to Irish-controlled waters. Nineteen such ships have been recorded passing through ireland’s Economic Zone (EEZ) as May, a stark rise from previous months and a growth prompting heightened vigilance from Irish defense and transport authorities.

These shadow fleet vessels are characterized by their involvement in deceptive practices to transport sanctioned oil and other cargo, often circumventing international regulations.Many are registered in jurisdictions with limited capacity or willingness to enforce maritime law.A notable portion of these ships have exhibited unusual navigation patterns, including the adoption of economically inefficient routes and deviation from established shipping lanes.

The escalating presence of these vessels has led to increased monitoring by the Defence Forces and the Department of Transport, driven by apprehension over potential environmental hazards and national security implications.Russia, facing broad sanctions as its full-scale invasion of Ukraine in 2022, has increasingly utilized this shadow fleet to supply its oil and natural gas to markets in the Global South.

Of the 19 vessels tracked near Ireland, 18 were identified as crude oil tankers, with a dozen carrying full oil loads. The majority of these ships are subject to European Union sanctions, with others falling under US or UK restrictions. This surge contrasts sharply with the more sporadic appearances of Russian vessels in Irish waters previously.

Specific incidents have amplified authorities’ concerns. Recently, tankers Sierra and Marathon, departing from a Baltic Sea port with crude oil bound for India, chose a circuitous route around the north of Ireland into the North Atlantic, rather than the more direct and economical English channel. Maritime analysts suggest such deviations are not made without reason, pointing to a potential increase in scrutiny in other key maritime areas.

Indeed,the UK has reportedly intensified its monitoring of shadow fleet activity off its coast,challenging an average of 40 such vessels monthly as part of a broader European initiative to combat Russian sanctions evasion. Some tankers have also appeared to be deliberately avoiding designated reporting areas where cargo details are typically disclosed, further complicating oversight.

The condition of many shadow fleet vessels, frequently enough described as old and poorly maintained, presents a significant environmental risk. Overworked and potentially inexperienced crews exacerbate these concerns. The potential cost of an oil spill from a single such tanker could reach an estimated €750 million, underscoring the critical need for robust monitoring and preparedness. The Irish authorities are now enhancing their surveillance capabilities to address these growing challenges.

What specific international maritime law is violated when vessels disable their Automatic Identification System (AIS) transponders?

Russian ‘Shadow Ships’ Surge in Irish Waters: A Growing Security Concern

The Increase in Unidentified Vessels

Over the past year, Irish authorities have observed a significant increase in the presence of russian-linked vessels operating in its Exclusive Economic Zone (EEZ) and territorial waters. these ships, often referred to as “shadow ships” or “dark vessels,” frequently engage in suspicious activities, raising concerns about potential espionage, infrastructure vulnerability assessments, and even preparations for potential sabotage. The surge in activity coincides with heightened geopolitical tensions following the invasion of Ukraine and increased scrutiny of Russian maritime activity globally.

This isn’t simply a matter of increased shipping traffic. The defining characteristic of these vessels is their purposeful obfuscation – turning off Automatic Identification System (AIS) transponders, engaging in ship-to-ship transfers, and exhibiting unusual maneuvering patterns. This behavior instantly flags them as requiring closer inspection.

Identifying the ‘Shadow Fleet’ – Tactics and Techniques

The term “shadow fleet” encompasses a range of vessels, but several common characteristics define the current surge around Ireland:

AIS Spoofing & Dark Activity: The most prevalent tactic. Vessels switch off their AIS transponders, making them invisible to standard maritime tracking systems. This is a clear violation of international maritime law (SOLAS Convention) and a strong indicator of illicit activity.

Ship-to-Ship (STS) Transfers: Frequent STS transfers, particularly involving oil and gas products, are observed. These transfers can be used to circumvent sanctions, disguise the origin of cargo, and potentially facilitate the transfer of prohibited goods.

Loitering Near Critical Infrastructure: Several vessels have been documented loitering near subsea cables, gas pipelines, and wind farms – vital components of Ireland’s energy and communications infrastructure.

Unusual maneuvering: Erratic or unexplained changes in course and speed, often combined with AIS manipulation, are common indicators.

Linked to Sanctioned Entities: Many of these vessels are demonstrably linked to companies or individuals already subject to international sanctions related to the conflict in Ukraine.

Key Subsea Cable Hub: Ireland is a major landing point for numerous transatlantic subsea cables carrying the vast majority of global internet traffic. Disrupting these cables would have catastrophic consequences.

Energy Infrastructure: The country is increasingly reliant on offshore wind energy and has significant natural gas infrastructure, both of which are potential targets.

EU access Point: Ireland’s position as an EU member state and its access to European markets make it a potential transit point for sanctioned goods.

Limited Maritime Surveillance: While the Irish Naval Service is capable, it faces resource constraints and challenges in monitoring a vast maritime area.

February 2024: The Irish naval Service intercepted a Russian-linked vessel, the Sevastopol, engaging in suspicious activity near the Kinsale Head gas field. The vessel was observed repeatedly switching off its AIS.

June 2024: Multiple reports surfaced of unidentified vessels conducting detailed surveys near subsea cable landing stations along the Irish coastline.

Ongoing Monitoring: the Irish Security Services (including the Defense forces and Garda Síochána) are continuously monitoring identified vessels of interest, sharing intelligence with international partners.

Increased Naval Patrols: In response to the escalating situation,the Irish naval Service has increased patrols in key areas,focusing on surveillance and interception capabilities.

Sanctions circumvention: STS transfers allow Russia to continue exporting oil and gas products despite international sanctions, generating revenue to fund the war in Ukraine.

Infrastructure Mapping: The loitering and surveying activities suggest a deliberate effort to map and assess the vulnerability of critical infrastructure. This information could be used for future sabotage or disruption.

Intelligence Gathering: Vessels may be equipped with sophisticated sensors to gather intelligence on naval movements, communications infrastructure, and other sensitive data.

International Cooperation & Response

Addressing this growing security concern requires a coordinated international response.

Information Sharing: Ireland is actively collaborating with EU partners,NATO allies,and other countries to share intelligence and coordinate maritime surveillance efforts.

Enhanced Maritime Domain awareness (MDA): Investing in advanced MDA technologies, such as satellite tracking, radar systems, and data analytics, is crucial for detecting and tracking suspicious vessels.

Strengthened Enforcement: Increased enforcement of maritime regulations, including penalties for AIS manipulation and illegal STS transfers, is necessary.

Joint Naval exercises: Conducting joint naval exercises with allied nations can enhance interoperability and demonstrate a commitment to maritime security.

Protecting Critical Infrastructure: Practical Steps

While the obligation for national security rests with the government,individuals and businesses can take steps to enhance security awareness:

* Report Suspicious Activity: Report any unusual maritime activity to the
