About the Organizations

Six months of dramatic enforcement actions and military escalation have transformed the shadow fleet crisis, but the environmental threat remains the core concern.

In August 2025, SEVENSEAS Media published my article “The Shadow Fleet Crisis: When Ocean Conservation Meets Global Security,” which examined the emerging environmental threat posed by the global shadow fleet: more than 700 aging, poorly maintained tankers operating outside international law, carrying millions of barrels of oil through the world’s most sensitive marine ecosystems. I called for proactive intervention to prevent an uncontrollable environmental catastrophe. This article provides a six-month update on that crisis, and documents how dramatically the situation has evolved.

As I explained in that earlier piece, a single oil tanker grounding in a region such as the Caribbean could result in the destruction of acres of coral reef, the oiling of miles of island and coastal shoreline, the death of vital populations of fish and other species, and permanent harm to the economies of many coastal communities. The potential for widespread harm is amplified by the lack of response capacity and adequate funding mechanisms in the Caribbean and along trade routes through vulnerable areas.

At that time, there were fairly straightforward options for addressing the threat that vulnerable island states and the conservation community could pursue. What I could not have predicted was how rapidly the situation would escalate; not toward resolution, but toward a confrontation that has now drawn in navies, fighter jets, and the highest levels of government from multiple nations.

The shadow fleet crisis has transformed from a maritime environmental concern into a more complicated geopolitical scenario. But amid all the dramatic headlines about seizures and naval escorts, we must not lose sight of what matters most from an ocean conservation perspective: the environmental threat has grown more urgent, not less.

U.S. forces have seized seven sanctioned tankers in rapid succession. Russia has deployed military assets to protect shadow fleet vessels. France intercepted a tanker in the Mediterranean. NATO has established a new task force. These geopolitical developments complicate, but do not diminish, the environmental risks posed by aging, poorly maintained vessels carrying millions of barrels of oil.

A Note on Terminology: Shadow Fleet vs. Sanctioned Vessels

The terms “shadow fleet” and “sanctioned vessels” are often used interchangeably, but from an environmental perspective, they describe fundamentally different categories of risk.

A “sanctioned vessel” is any ship designated as violating trade sanctions, typically for carrying oil from Russia, Iran, Venezuela, or North Korea. Some sanctioned vessels continue to maintain insurance, undergo regular inspections, employ professional crews, and comply with maritime safety standards. These vessels represent a trade dispute: politically contentious, but far less threatening to marine ecosystems.

The “shadow fleet,” by contrast, refers specifically to vessels that combine sanctions evasion with wholesale abandonment of maritime safety infrastructure. These ships operate with falsified documentation, lack legitimate insurance, use aging and poorly maintained equipment, exploit their crews, and engage in dangerous practices such as turning off AIS transponders, refusing pilot services, and conducting risky ship-to-ship cargo transfers at sea.

The distinction matters for policy. When a shadow fleet vessel reflags to Russia (as more than 40 have done since June 2025), it gains state protection but does not necessarily improve its safety profile. The environmental threat persists regardless of which flag is painted on the stern.

Geopolitical Context: A Complicating Factor

The past six months have seen extraordinary geopolitical developments that have complicated, though not fundamentally changed, the environmental calculus. Understanding these events is important, but we should view them as context rather than as the core story.

On December 10, 2025, U.S. forces seized the Venezuelan oil tanker Skipper in international waters between Grenada and Trinidad; notably, on the high seas rather than within any nation’s Exclusive Economic Zone (EEZ). In a dramatic made-for-TV move, armed law enforcement agents rappelled from helicopters onto a vessel carrying nearly 2 million barrels of crude oil. The crew, mostly Russian nationals, offered no resistance. After U.S. forces seized the oil tanker Skipper near Venezuela, they took control of the crew and cargo. They redirected the vessel to the Texas coast off Galveston for forfeiture proceedings and likely offloading.

But the Marinera chase was something else entirely. For eighteen days, U.S. Coast Guard vessels pursued the tanker (previously Guyana-flagged and known as Bella 1) across the Atlantic Ocean. During the pursuit, the crew hastily painted a Russian flag on the hull. Russia formally added the vessel to its Maritime Register and demanded the U.S. halt pursuit. Moscow dispatched a naval escort. The U.S. intercepted the vessel between Iceland and Scotland before Russian ships arrived. After U.S. and allied forces seized the Marinera in the North Atlantic, they placed the crew in U.S. custody. They moved the tanker to the United States to enter judicial forfeiture proceedings as a stateless, sanctions-violating “shadow fleet” vessel, with those involved in its escape attempt facing potential prosecution under U.S. law.

By January 21, the United States had seized seven sanctioned tankers in rapid succession. France, with UK intelligence support, intercepted the tanker Grinch in the western Mediterranean. President Macron personally ordered the operation.

Russia responded by abandoning any pretense of plausible deniability. More than 40 shadow fleet tankers have switched to the Russian flag since June 2025, with 21 reflagging immediately following the Skipper seizure. In May 2025, Russia deployed a Su-35 fighter jet in response to Estonia’s attempt to stop the tanker Jaguar, the first overt military intervention to protect a shadow fleet vessel.

All seven U.S. seizures occurred on the high seas, in international waters beyond any nation’s territorial sea or EEZ. Under traditional maritime law, flag states exercise primary jurisdiction over their vessels on the high seas. The high-seas location makes these actions legally complex, and helps explain why Russia felt emboldened to dispatch naval escorts and why France ultimately had to release the Grinch.

These geopolitical confrontations have significant implications, but from an environmental perspective, the key question remains unchanged: Are these vessels safe? The answer remains no, regardless of whose flag they fly. Vessels that operated as poorly maintained shadow-fleet tankers last month do not suddenly become environmentally sound simply because they fly a Russian flag this month. The aging hulls, inadequate maintenance, undertrained crews, and missing insurance that made them environmental hazards persist.

The Core Environmental Risks: Compounding Threats

Our ongoing research into the shadow fleet has revealed multiple compounding risks that threaten marine ecosystems worldwide. These hazards exist independently of the geopolitical drama, and in many ways are exacerbated by it.

Aging vessels and inadequate maintenance have led to Russia’s shadow fleet expanding from fewer than 100 vessels in February 2022 to over 343 vessels today. Before Russia invaded Ukraine in 2022, just three percent of the global tanker fleet was more than 20 years old. That share has more than tripled to 11%. The newly sanctioned vessels are an average of 16.8 years old. Some shadow fleet vessels have been documented using single-hull designs for oil transport, configurations banned under international regulations precisely because of their vulnerability to catastrophic failure.

Inadequate insurance: Over 70% of shadow fleet vessels lack adequate coverage through International Group P&I clubs. When tankers are uninsured or underinsured, coastal states bear the cost of environmental cleanup and damage. There is no readily available funding mechanism for rapid response mobilization.

Crew competence and exploitation: Reports indicate that forced labor and human trafficking in the maritime sector remain severe problems. Crews are often ill-equipped to handle the unique navigational challenges of regions such as the Baltic Sea, where harsh winter weather, ice cover, and narrow shipping lanes require specialized training. The data we have reviewed shows that there have been significant increases in the number of tankers refusing to use experienced Danish pilots when navigating the Baltic’s dangerous shipping straits. This troubling trend has accelerated, rising from 1 in 20 in July 2023 to 1 in 5 tankers in July 2024.

Navigation interference: GNSS jamming and spoofing (the deliberate interference with satellite navigation systems) has become endemic in certain maritime regions. The Baltic Sea has experienced persistent navigation interference that degrades situational awareness and increases the risk of collisions and groundings.

A Growing Crisis: Abandoned Vessels

A troubling new dimension of the shadow fleet crisis has emerged: the dramatic increase in abandoned vessels. According to the International Transport Workers’ Federation (ITF), ship abandonments have skyrocketed from 20 vessels worldwide in 2016 to 410 in 2025, with 6,223 merchant seafarers left stranded. Both figures were up by almost a third from the previous year.

The ITF reports that shadow fleet vessels are contributing significantly to this spike. These aging vessels of obscure ownership, often unseaworthy and uninsured, are being abandoned when operations become unprofitable or when enforcement pressure increases. Flags of convenience (FOC) vessels accounted for 82% of all abandonments in 2025.

From an environmental perspective, abandoned vessels represent a compounding risk. A tanker abandoned with cargo aboard (as has occurred with several vessels carrying hundreds of thousands of barrels of Russian crude) is an environmental time bomb. Without an active crew to maintain systems, monitor conditions, or respond to emergencies, the risk of cargo spill, leak, or loss increases dramatically. When owners disappear into shell company structures and flag states disclaim responsibility, there is no one to hold accountable for cleanup costs.

The human dimension compounds the environmental risk. Abandoned crews face shortages of food, fresh water, and essential supplies. Unpaid, hungry, and demoralized seafarers cannot be expected to maintain vessel safety systems or respond effectively to emergencies. Last year, abandoned merchant navy crews worldwide were owed a total of $25.8 million in unpaid wages.

Infrastructure Incidents: Evidence of Operational Hazards

A series of incidents in the Baltic Sea demonstrated, in dramatic fashion, the operational hazards posed by shadow fleet vessels. While media attention focused on the infrastructure damage and potential that these acts are sabotage, the incidents also reveal how poorly these vessels are operated, and what that means for environmental risk.

On Christmas Day 2024, the Russian oil tanker Eagle S, operating under a Cook Islands flag, cut the Estlink 2 power cable and four data cables by dragging its anchor for 62 miles through Finnish waters. Whether intentional sabotage or negligent operation, this incident demonstrates the reality: a vessel dragging its anchor for 62 miles is a vessel that could be dragging through even more sensitive marine habitat or run aground on a reef.

Finnish authorities seized the Eagle S and found 32 safety deficiencies, including problems with fire protection, navigation equipment, and ventilation systems. The vessel’s S-band radar did not work. Its insurance had expired months earlier. This is the condition of the vessels carrying millions of barrels of oil through our oceans. The Eagle S was released after three months of detention but was subsequently scrapped in Turkey in late 2025.

These same vessels, uninspected, poorly maintained, operated by crews who manipulate navigation systems to avoid detection, are navigating congested waterways where a single miscalculation could result in catastrophic collisions and spills. The infrastructure sabotage concern and the environmental concern are two sides of the same coin: vessels operating outside established safety systems pose threats everywhere they operate.

Beyond Sanctions Evasion: The Hybrid Warfare Dimension

Our research has also revealed concerning evidence that some shadow fleet vessels serve purposes beyond oil transport. In July 2025, Danish pilots reported crew members photographing bridge infrastructure during transit. A Danwatch investigation found that many shadow fleet crew members had backgrounds in Russian defense or intelligence services. Swedish naval authorities documented unusual antenna configurations suggesting intelligence-gathering capabilities.

In August 2025, drawing on the accumulating evidence from DanPilot reports, the Danwatch investigation, and Swedish Navy observations, the U.S. Naval Institute’s Proceedings published an analysis concluding that shadow fleet vessels should be viewed as “multirole tools” for sanctions evasion, intelligence collection, and potential sabotage.

NATO responded by announcing its “Baltic Sentry” operation. Germany established Commander Task Force (CTF) Baltic, a shore-based tactical maritime headquarters at Rostock that coordinates frigates, patrol aircraft, submarines, and naval drones to protect undersea infrastructure.

This hybrid warfare dimension is concerning in its own right, but for ocean conservation purposes, it reinforces a key point: these are not normal commercial vessels subject to normal oversight. They operate in a gray zone where the usual assumptions about vessel behavior, crew competence, and emergency response cannot be trusted. This uncertainty compounds environmental risk.

When Disaster Strikes: The Response Capacity Gap

The January 2026 seizures in the Caribbean highlighted a vulnerability that extends far beyond enforcement. What happens when a shadow fleet vessel spills its cargo in waters that lack the infrastructure to respond?

In European waters, the European Maritime Safety Agency operates 20 pollution response vessels and maintains satellite monitoring through its CleanSeaNet service. But even this capacity has gaps; remarkably, there are currently no EMSA pollution response vessels stationed in the Baltic Sea, despite the concentration of shadow fleet activity in those waters.

The Caribbean and Latin America would face even greater challenges in the event of a catastrophic spill. When U.S. forces seized the Skipper between Grenada and Trinidad, they intercepted a vessel carrying enough oil to devastate marine ecosystems and the economies that depend on them. These coastal states lack response infrastructure, equipment pre-positioning, and coordinated contingency planning. Local and migratory fisheries, fragile reef and mangrove areas, and coastal tourism remain at serious risk.

The insurance gap compounds this vulnerability. With no guarantee of repayment, communities may have to choose between mounting expensive cleanup efforts with uncertain cost recovery and continuing to provide ordinary but necessary services to their residents.

The Enforcement Paradox

The Grinch case exposed a critical gap in the legal framework. When France intercepted the vessel, President Macron declared it a triumph of sanctions enforcement. Three weeks later, he informed Ukrainian President Zelensky that France would be forced to release the tanker because current French and international maritime law do not permit prolonged detention of civilian vessels, even when under sanctions.

This is not an argument against enforcement. It is an observation that enforcement alone cannot solve the environmental crisis. The shadow fleet continues to grow. Russia’s seaborne oil exports now account for almost 70% of shipments via shadow-fleet vessels. Iran maintains exports of approximately 1.6 million barrels per day. The total reaches approximately 3.7 billion barrels annually: 6 to 7 percent of global oil flows moving in vessels that operate outside safety systems designed to protect marine environments.

The Path Forward: Focusing on Environmental Protection

The conservation community faces the same choice I outlined six months ago, but with greater urgency. The shadow fleet crisis has attracted the attention of governments, militaries, and international institutions. It has become a subject of great power competition. But amid all this geopolitical attention, the environmental dimension remains neglected.

What the crisis demands is not a political position on sanctions. It is a relentless focus on the environmental consequences of vessels operating outside established safety systems, regardless of whose flag they fly or whose cargo they carry.

What can nations do? Coastal states can strengthen Port State Control regimes: refusing entry to suspicious vessels, demanding proof of adequate insurance, and requiring comprehensive documentation of cargo origin. The EU’s approach of denying port access to vessels that turn off their AIS transponders provides a model. Nations can enforce MARPOL requirements, including the 48-hour notification for ship-to-ship transfers in their territorial seas or EEZ. Financial pressure matters too: targeting insurance providers, financiers, and service providers that enable shadow fleet operations can significantly increase operational costs and risks.

What should the ocean conservation community do? First, we must acknowledge this issue as part of our mandate. The shadow fleet threat is not separate from ocean conservation; it is a direct and growing threat to marine ecosystems. Second, we need to invest in monitoring and documentation. Organizations like SkyTruth have demonstrated how satellite imagery and remote sensing can expose environmental violations. Third, we must develop and advocate for risk-based policy frameworks that distinguish between environmental compliance and political affiliation, frameworks that create incentives for safety even within sanctioned trade. Fourth, we should build regional response capacity, particularly in vulnerable areas such as the Caribbean. Finally, we need to bring our collective voice to international forums (the IMO, UNCLOS processes, and bilateral negotiations) to ensure that environmental protection remains central to any framework addressing the shadow fleet crisis.

The window for proactive intervention remains open, but it will not remain open indefinitely. The current period of heightened attention offers an opportunity to establish frameworks before a catastrophic incident forces reactive responses. The question is whether the conservation community will rise to meet this challenge, or whether we will wait for the next spill, the next grounding, the next preventable disaster to force our hand.

The Ocean Foundation will continue to monitor developments and share what we learn. The ocean deserves better. The choice, as always, belongs to all of us.

Editor’s Note: Why We Are Featuring Iran Now

Iran is once again dominating headlines.

From widespread public demonstrations that surged across Iran in late 2025 into early this year, to the current escalation and the breaking of war, the country is being discussed globally in the context of politics, conflict, and human suffering. The loss of life and instability unfolding are real and devastating. Nothing in this feature is intended to diminish that reality.

But there is something else that often goes unspoken.

For years, inside and outside of environmental circles, people have quietly asked me a question. Sometimes with curiosity. Sometimes with hesitation. Sometimes almost with guilt.

“What is actually there?”

They were referring to biodiversity.

In today’s world, there is pressure to already know. When the breadth of human knowledge appears to sit at our fingertips, asking basic questions can feel uncomfortable. If a place overlaps with your professional field or your moral concern, you are expected to understand it fully.

Curiosity, however, should never carry shame.

At SEVENSEAS Media, we see questions as bridges. When a region becomes defined only by conflict, it becomes even more important to remember that it is also defined by landscapes, species, ecosystems, culture, and people who have lived in relationship with nature for millennia.

Iran is not only a geopolitical flashpoint. It is a country of vast mountain ranges, ancient forests, wetlands, deserts, coral communities, migratory flyways, and one of the most strategically significant marine corridors in the world. It sits at the intersection of terrestrial and marine biodiversity, connecting ecosystems across Central Asia, the Caucasus, the Arabian Peninsula, and the Indian Ocean.

It is home to coastal communities whose fishing traditions stretch back centuries, to wetlands that host migratory birds crossing continents, and to marine systems that sustain life far beyond their shorelines.

This feature has been in development for some time. In light of current events, we believe it is important to move forward thoughtfully and with care.

Education is not a distraction from suffering. It is part of long term resilience.

At SEVENSEAS Media, we promote education and peace across cultures and living in harmony with nature. We believe that understanding biodiversity can humanize places that are otherwise reduced to headlines. Conservation, at its best, transcends politics and builds shared responsibility for the natural world.

In the articles that follow, we explore the geography of Iran, its terrestrial biodiversity, its migratory importance, and its ocean and coastal ecosystems. We touch on traditional fishing cultures, current pressures, conservation challenges, and the organizations working to protect what remains.

As always, we are not here to simplify complexity. We are here to make space for informed curiosity and careful understanding.

In moments of conflict, it can feel easier to look away. We choose instead to look closer, and to recognize that ecological systems persist regardless of political borders.

This story is developing rapidly. Details may shift as the situation evolves. Last verified: March 3, 2026.

The headlines are dominated by oil prices, geopolitical brinkmanship, and military escalation. But below the waterline of the Persian Gulf, a quieter catastrophe is taking shape, one that will outlast any ceasefire.

The Persian Gulf is not the barren petrochemical corridor that its reputation might suggest. It is a semi-enclosed sea of roughly 241,000 square kilometres, averaging just 35 metres in depth, connected to the wider Indian Ocean only through the 56-kilometre-wide Strait of Hormuz. Within this shallow, hypersaline basin lives a marine community that has adapted to conditions most ocean species could not survive: summer surface temperatures regularly exceeding 35°C, salinity levels above 45 PSU, and winter cooling that can plunge below 18°C. The organisms that thrive here are not merely surviving. They are demonstrating resilience strategies that climate scientists around the world are studying with increasing urgency.

Approximately 60 species of reef-building coral have been documented in the Gulf, including the endemic Acropora arabensis, found nowhere else on Earth. These corals withstand water temperatures of up to 36°C, well beyond the 32°C threshold that triggers bleaching in most tropical reefs. Researchers have increasingly turned to Persian Gulf coral populations as living laboratories for understanding how reef organisms might adapt to a warming planet. The Gulf also supports the world’s second-largest population of dugongs, after northern Australia, with an estimated 7,500 individuals grazing on seagrass beds along the coasts of Qatar, Bahrain, the UAE, and Saudi Arabia. Over 700 species of fish, populations of hawksbill and green sea turtles, Indo-Pacific humpback dolphins, whale sharks, and migratory seabird colonies all depend on this ecosystem.

The Immediate Threats

The environmental risks now facing this ecosystem are layered and compounding.

Oil contamination is the most visible concern. At least three commercial tankers have been struck by projectiles, with one confirmed ablaze and producing thick plumes of black smoke near Omani waters. A burning tanker does not simply release crude oil; it generates a toxic cocktail of partially combusted hydrocarbons, heavy metals, and particulate matter that settles across surrounding waters. With more than 150 laden tankers now anchored in open Gulf waters, the risk of collision, grounding, or further military targeting grows with each passing day. The shallow depth of the Gulf, averaging just 36 metres, means that spilled oil reaches the seafloor and coastal habitats far more quickly than in open ocean environments.

The sinking of at least nine Iranian warships introduces a different category of pollution. Sunken military vessels carry bunker fuel, hydraulic oils, lubricants, and munitions, all of which corrode and leach into surrounding waters over years and decades. A 2023 IUCN brief estimated that globally, over 8,500 shipwrecks are at risk of leaking approximately six billion gallons of oil. The Persian Gulf’s warm, shallow conditions accelerate corrosion, meaning these newly sunken warships could begin releasing contaminants faster than wrecks in colder, deeper waters.

Underwater noise pollution from military operations, including sonar, detonations, and sustained engine activity from hundreds of anchored vessels, adds biological stress. Marine mammals such as dugongs and dolphins rely on acoustic communication for feeding, mating, and navigation. Prolonged noise disruption can displace populations from critical habitats, with consequences that persist long after the sound stops.

Reports of potential mine-laying by Iranian forces introduce yet another dimension. Naval mines are indiscriminate by design; they threaten not only vessels but also the seabed itself, disturbing sediment and destroying benthic habitats when detonated. GPS jamming, confirmed across the region, increases the likelihood of navigational accidents among the hundreds of ships now attempting to shelter in place.

History’s Warning

The Persian Gulf carries the scars of previous conflicts. During the 1991 Gulf War, an estimated 4 to 11 million barrels of crude oil were deliberately released into its waters, covering more than 600 kilometres of Saudi coastline. Research conducted by Jacqueline Michel in 2010 found that oil had penetrated up to 50 centimetres into Gulf sediments and remained detectable 12 years after the spill. A 2017 study by Joydas et al. found “alarming levels” of hydrocarbons persisting in secluded bay areas more than 25 years later. While fish and bird populations showed encouraging recovery by 1994, the long-term contamination of sediments and coastal habitats tells a more complicated story.

The Gulf ecosystem did recover from 1991, a testament to its remarkable resilience. But it recovered into a world with fewer stressors. Today, the same ecosystem faces compounding pressures from coastal development, desalination plant discharge, climate-driven temperature extremes, and chronic oil pollution from routine shipping. A 2024 review published in Marine Pollution Bulletin found that 63.5% of the Gulf’s key habitats and species remain “data-deficient,” while 21.2% show documented decline. The margin for absorbing another major environmental shock has narrowed considerably.

What Comes Next

The environmental consequences of this crisis will not be determined by the conflict’s duration alone, but by what happens when it ends. After 1991, clean-up efforts focused almost exclusively on oil recovery from the water’s surface, while coastal habitats were largely neglected. If history offers any instruction, it is that the environmental response must begin alongside the military and diplomatic response, not after it.

International bodies, including the Regional Organization for the Protection of the Marine Environment (ROPME) and the International Maritime Organization, will need to coordinate rapid environmental assessment once conditions allow. Monitoring of coral communities, seagrass beds, and dugong populations should be prioritized, alongside sediment sampling near tanker anchorage sites and sunken vessel locations.

The Persian Gulf’s marine life has survived environmental extremes that would have destroyed ecosystems elsewhere. It has endured the largest deliberate oil spill in history and emerged, battered but functional. Whether it can absorb another round of military trauma on top of everything the 21st century has already thrown at it is a question that marine scientists are watching with deep concern, and one that the rest of us should be paying attention to as well.
