In 2025, a series of underwater explosions targeting oil tankers has raised alarms across the global maritime industry. The latest attack on the Seajewel, a Greek-operated Aframax crude oil tanker, is just one of several incidents highlighting new threats to shipping security. As geopolitical tensions rise, these events threaten to disrupt global freight flows, increase operational costs, and reshape maritime risk management.

What’s Happening? The Seajewel Incident and Beyond

On February 2025, the Seajewel was struck by two underwater explosions while docked at Italy’s Port of Savona. The damage—while localized—marked a concerning escalation. Other recent incidents include:

January 2025: The Seacharm, another Greek-operated tanker, was damaged by a similar explosion off Turkey’s coast.
February 2025: The Koala, a Cyprus-owned vessel, suffered hull damage from an underwater explosion at Russia’s Ust-Luga port.

While investigations are ongoing, these attacks have raised critical concerns for global shipping security.

Why This Matters: The Ripple Effect on Global Trade

These incidents aren’t just isolated threats—they have far-reaching implications for global logistics:

Supply Chain Delays: Increased security measures at ports and rerouting of vessels will extend transit times.
Rising Insurance Costs: Following security threats in the Red Sea, some war-risk insurance premiums surged by up to 900%—a trend that could repeat if these underwater attacks escalate.
Geopolitical Instability: If these explosions are linked to Russian oil trade or sabotage, shipping lanes could face new restrictions and diplomatic fallout.
Environmental Risks: A breached tanker hull could lead to oil spills, threatening marine ecosystems and increasing cleanup costs.

What’s Driving These Attacks?

While no conclusive evidence has emerged, several possible motives include:

Targeting Russian Oil Trade: Some analysts suspect attacks are aimed at disrupting oil shipments linked to Russian energy exports.
Sabotage & Terrorism: The use of limpet mines or underwater explosives suggests coordinated efforts by state or non-state actors.
The Shadow Fleet Factor: Many tankers operating in Russian oil transport remain opaque in ownership, raising security concerns over which vessels are being targeted.

How Can the Maritime Industry Respond?

Invest in Underwater Surveillance: Ports should deploy sonar-based detection systems to identify potential underwater threats.
Rethink Route Planning: Operators should assess whether diversifying shipping lanes can mitigate exposure to high-risk regions.
Strengthen Risk Management: Expect insurers to adjust premiums for tankers operating in vulnerable waters—early engagement with risk consultants is key.
Increase Intelligence Sharing: Governments and shipping alliances must improve threat intelligence coordination to prevent further attacks.

Securing the Future of Maritime Trade

The recent explosions targeting tankers are a stark reminder that maritime security is evolving. From traditional piracy to sophisticated underwater attacks, logistics service providers and shipping operators must stay ahead of emerging threats.

With proactive security investments, strategic route planning, and closer industry collaboration, businesses can protect their assets and ensure supply chain resilience. The risks may be rising, but with the right approach, the global shipping industry can navigate these challenges safely.
