Venezuela Uses Tankers as Floating Storage, Onshore Tanks Overflow

Venezuela’s state oil company has begun loading crude and fuel oil into tankers and keeping those vessels anchored in national waters as onshore storage inventories swell, company documents and shipping data show. The tactic, used in prior years when tank farms fill, was deployed again after a weekend of transfers to relieve pressure at terminals that are rapidly reaching capacity.

Production across Venezuela is running at roughly 1.1 million barrels per day, a flow that has contributed to a swift build up of inventories. Pressure is particularly acute at the Jose terminal, which receives extra heavy crude from the Orinoco Belt and now faces bottlenecks as onshore tanks approach their limits. Rather than curtail output, state operators have moved volumes to tankers, effectively using the vessels as floating reservoirs while they await export clearance.

The decision follows a series of recent maritime enforcement actions by U.S. authorities that targeted vessels suspected of participating in sanctions evasion operations known as the shadow fleet. Earlier in December the U.S. Coast Guard intercepted two tankers, the Skipper and the Centuries, in the Caribbean Sea, both reported to be fully loaded with Venezuelan crude. Those interceptions, along with other reported seizures, have added logistical complexity and are cited internally as drivers of the temporary reliance on anchored tankers.

For coastal communities the floating storage strategy poses multiple risks. Anchored tankers carry an elevated danger of spills, pollution and leaks that can damage fisheries and local food supplies. Many communities along Venezuela’s Caribbean coast rely on small scale fishing and coastal tourism for income and nutrition, making them particularly vulnerable to maritime contamination. Health services are also at stake. Fuel is essential for powering hospitals, clinics and water treatment in a country that already faces shortages of medicines and medical supplies. Disruption to export logistics can reduce state revenue that underwrites imports of drugs, vaccines and public health programs, exacerbating existing inequities in access to care.

The choice to avoid cutting production reflects a calculation by oil managers to preserve exportable volumes and contractual relationships. President Nicolas Maduro addressed the tensions in a televised speech, asserting continued cooperation with foreign oil partners and pledging that shipments tied to Chevron would proceed. He said, “(Under) rain, thunder, or lightning, and regardless of any conflicts, the contract with Chevron will be fulfilled. We are serious, decent people.”

Policy questions loom large. Sanctions and maritime interdiction aim to pressure Caracas over political grievances, but the resulting logistical distortions can produce collateral humanitarian effects. Humanitarian exceptions and clearer legal guidance for fuel tied to critical services could mitigate harms, yet the legal bases for recent interceptions and the exact quantities moved to individual tankers remain unclear. Public information does not fully enumerate the number of vessels now used as floating storage, their locations, or the volumes they hold.

As authorities on both sides weigh next steps, the immediate concern is protecting coastal populations and health infrastructure from the environmental and economic side effects of the storage shift. Without transparent coordination and contingency planning, the combination of full tank farms, anchored tankers and intermittent maritime enforcement risks deepening the social and health strains already felt across Venezuelan communities.
