The 159,800-cbm Maran Gas Delphi, which is carrying the LNG cargo, was on Thursday sailing in the Alboran Sea, offshore Spain, its AIS data provided by VesselsValue shows.
It is expected to arrive in Cartagena on Friday, the data shows.
However, the vessel could change its destination in the meantime.
LNG Prime contacted Eni to comment on the delivery.
Earlier this month, the Nguya FLNG unit shipped the first cargo, marking the start of exports of the second phase of the Congo LNG project.
With Phase 2, the Congo LNG project reaches a total liquefaction capacity of 3 million tonnes per annum (mtpa) of LNG, equivalent to 4.5 billion cubic metres of gas per year, leveraging gas resources from the Nene and Litchendjili fields in the offshore Marine XII license.
China’s Wison New Energies built the 380-meter-long 2.4 mtpa FLNG, such as Tango FLNG, the first unit with a capacity of 0.6 mtpa, which began production in December 2023.
In August 2025, Eni hosted the sail-away ceremony for the Nguya FLNG unit in Shanghai, China.
Eni announced the arrival and introduction of gas to the FLNG unit at the beginning of December last year.
Congo LNG Phase 2 features three production platforms as well as the Scarabeo 5 unit dedicated to gas treatment and compression, and the Nguya FLNG for liquefaction and export.
According to Eni, Phase 2 start-up comes only 35 months after construction of the Nguya FLNG unit began, “setting a new international industry benchmark in terms of execution speed and efficiency.”
