Mexico increased exports of ultra-low sulphur diesel (ULSD) cargoes from state-owned Pemex's 340,000 b/d Olmeca refinery in November and December, after recently restarting shipments, according to vessel-tracking data and market sources.
Mexico had already exported its third and fourth ULSD cargoes in November, according to Kpler data, and added a fifth in November. Four additional cargoes were exported in December. Pemex had previously exported ULSD to the US and Central America in March and April.
The MR tanker Clearocean Milano loaded 300,000 bl of ULSD at the Dos Bocas port on 27 November. It discharged about 99,000 bl at a terminal near Newport, Rhode Island, and another 200,000 bl near Portland, Maine, Kpler data show.
The MR tanker Lakshmil loaded a similar volume on 22 November, discharging about 60,000 bl near New York and 230,000 bl near Providence, Rhode Island.
Three more MR tankers loaded ULSD at the Dos Bocas port in December. The Sti Bronx loaded about 300,000 bl of ULSD and discharged volumes across several US ports, including Cape Canaveral and Jacksonville, Florida; Charleston, South Carolina; and Providence.
The Nord Victorious loaded around 300,000 bl of ULSD at Dos Bocas and discharged cargoes in San Juan and Yabucoa, Puerto Rico. The Strimon also loaded about 300,000 bl and discharged roughly 120,000 bl at the Everglades port in Miami, Florida, though the bill of lading for the net discharge has yet to be confirmed, Kpler data show.
Construction of the Olmeca refinery began under former president Andres Manuel Lopez Obrador, but the project faced significant challenges.
Construction costs had more than doubled to $21bn as of 31 December 2024, according to Pemex data. In recent months, Pemex said the refinery has begun operating both refining trains, with crude processing rates exceeding 50pc of capacity.
Olmeca was initially highlighted as a crucial element in the government's strategy for road fuel self-sufficiency. But Pemex's trading arm PMI has also explored profitable ULSD export opportunities in Florida, the Caribbean and Central America, according to market sources. These regions rely heavily on imported diesel because of infrastructure limitations.
In September, the former head of PMI, Margarita Perez, stepped down from her role as director. Perez's replacement was Adan Garcia, the former head of non-tax and hydrocarbons revenue at Mexico's finance ministry.
