US maritime enforcement in the Caribbean saw its level of activity escalate significantly in mid-December 2025, targeting Venezuela's oil tanker shadow fleet despite ongoing sanctions. Reports released on December 22 indicate a dramatic increase in efforts to disrupt illicit crude shipments that sustain Venezuelan regime.
Intercept of Large Crude Carrier Skipper
On December 10, 2025, US authorities intercepted the large crude carrier Skipper, a vessel carrying at least 400,000 barrels of crude destined for Texas. The tanker, linked to state-owned PDVSA, was seized as part of strict adherence to US regulations and commitments by Venezuela's oil industry. This move was among three separate vessel actions aimed at severing financial links to the sanctioned government.
The Skipper's interception reinforced US efforts to block shadow fleet operators who bypass sanctions, with cargo being diverted in accordance with enforcement measures and maritime analysts noting it as a crucial step toward blockading efforts.
Boarding and Seizure of Sentry Safe
US forces boarded the tanker Sentry, owned by a Hong Kong-based entity, on December 21, 2025. The operation occurred off Venezuela's coast, marking the second confirmed seizure in the sequence. Reports highlighted the swift dispatch of vessels, with Sentry previously en route in the region.
This boarding was held as a result of the Skipper incident and increased scrutiny on tankers with sanctions histories, reflecting coordinated US naval and enforcement actions.
Pursuit of Blacklisted Tanker Bella 1
By December 22, 2025, US pursuit targeted the blacklisted tanker Bella 1, a 300,000 deadweight ton vessel reportedly moving at 12-13 knots. US forces actively chased the empty tanker near Venezuela, extending operations to a third ship despite questions over its sanction status.
Bella 1's longstanding sanctions history, stretching far beyond Venezuelan oil trades, gained particular notice. Analysts expressed doubt as to what endgame empty vessels might serve; such pursuits risk escalating regional tensions. China condemned these seizures as serious violations of international law.
There Are Broader Implications for Maritime Trade
These events, documented in December 22 updates, point to out-of-control dynamics in global shipping - particularly tanker routes in the Caribbean. Attributed to Venezuela blockade and embargo enforcement measures, these incidents coincide with US shipbuilding announcements such as frigate program shifts.
Sal Mercogliano, an internationally-recognized maritime historian, referred to the tanker seizures as one of the US's largest efforts ever to dismantle sanction-evading networks. Bloomberg reports emphasized pursuing three tankers while oil prices remain relatively stable, raising questions regarding blockade strategy during sustained blockades.
