The latest Dryad Global Maritime Intelligence Brief examines two fast-moving maritime risk stories with significant implications for commercial shipping, port operations and regional stability: the tightening maritime pressure around Cuba and escalating drone and missile activity across the Black Sea.
Together, these developments underline a broader trend: maritime risk is no longer confined to traditional security threats. Political pressure, sanctions enforcement, energy disruption, drone warfare, port attacks and commercial shipping exposure are increasingly converging into a more complex operating environment.
Cuba is facing a severe economic and humanitarian crisis, intensified by a tightened US-led energy blockade and sharp reductions in fuel imports. Nationwide blackouts, disruption to public services, food spoilage and rising public unrest are placing growing pressure on the Cuban government.
The maritime domain is now central to this crisis. Following US Executive Order 14404, issued on 1 May 2026, secondary sanctions on foreign entities engaged in Cuban trade have expanded significantly. Major international carriers including CMA CGM and Hapag-Lloyd have suspended bookings to and from Cuba, effective mid-May 2026.
This is expected to remove a substantial proportion of Cuba’s container shipping capacity, restricting imports of food, medicine, spare parts and other essential goods. While Crowley Maritime continues limited authorised services between Miami/Port Everglades and Mariel, broader commercial shipping traffic has declined sharply.
With the United States maintaining a robust naval, Coast Guard, aerial and UAV surveillance presence across the Caribbean, the effective monitoring perimeter around Cuba is deterring most third-party shipping and increasing compliance pressure on operators.
The Black Sea has also seen a marked escalation in drone and missile strikes targeting maritime infrastructure, energy terminals, ports and vessels.
Ukraine has carried out strikes against Russian Black Sea oil terminals and port infrastructure, including facilities near the Kerch Strait and the Port of Taman. These attacks targeted key export hubs used for oil, fuel, diesel and liquefied gas storage and transshipment.
Russia has responded with one of the largest sustained drone barrages of the war, targeting Ukrainian infrastructure including port facilities in Odesa. Further Ukrainian strikes have reportedly affected additional targets in the Black Sea and Sea of Azov, including cargo vessels, port cranes and naval communications infrastructure.
For commercial shipping, the risk environment remains highly volatile. Vessels operating near contested ports, energy infrastructure or shadow fleet activity face increased exposure to misidentification, collateral damage and disruption.
This week’s brief highlights how quickly maritime risk can shift when sanctions pressure, military activity, energy disruption and geopolitical signalling intersect.
For shipowners, operators, insurers, charterers and security teams, the key issue is not simply whether a route remains technically open. It is whether the wider operating environment supports safe, compliant and commercially viable movement.
