Yinson Production will increase the gas export capacity of the John Agyekum Kufuor production vessel, off Ghana, by more than 60% under an amendment signed on 2 October with Eni Ghana and announced on 5 October. Capacity is to rise from about 210 to 220 million standard cubic feet per day to 355 million in the first quarter of 2028.
The work will involve installing two modules above the vessel. The first will include two compressors driven by gas turbines, while the second will process the additional volumes. This equipment is intended to offset the expected decline in reservoir pressure and maintain transport to the coast.
The amendment represents an additional estimated value of 810 million dollars for the work, the new daily rates and the extension of the contract. About 600 million is expected to go to the Yinson group. This amount corresponds to an order book and not to Ghanaian public spending, nor to the physical cost of the equipment alone.
The firm charter period of the vessel will be extended by four years, until 2036. Yinson holds 74% of the company that owns the vessel. The remainder belongs to a Japanese consortium comprising Sumitomo, Kawasaki Kisen Kaisha, JGC Holdings and the Development Bank of Japan.
The vessel operates on the Offshore Cape Three Points development, which includes the Sankofa and Gye Nyame fields in the Tano basin, about 60 kilometres off the coast. Eni operates the project with Vitol and the Ghana National Petroleum Corporation. The gas produced is intended for the domestic market and mainly feeds power plants.
Higher capacity can limit occasional recourse to fuel oil or diesel when gas is short, which reduces exposure to imports and international price swings. It does not, however, guarantee an automatic fall in electricity bills. The outcome will depend on the average cost of gas set by the regulator, the availability of onshore infrastructure and the operation of the power plants.
In July 2025, Eni had said the OCTP non-associated gas system had already been raised from 246 to 270 million cubic feet per day and was supplying about 70% of domestic gas. The new investment aims for a further step, with reinforced compression and processing to support the evolution of the reservoir.
Engineering, procurement and fabrication operations must be carried out without interrupting production. Yinson has identified risks relating to schedule, cost overruns and regulatory compliance. The first-quarter 2028 date therefore remains a delivery target, not production already secured.
