Guyana has outlined plans for its seventh sanctioned offshore oil project, Hammerhead, which is expected to begin production in 2029. Central to the development is a 13-kilometre subsea pipeline designed to carry an estimated 95 million standard cubic feet of natural gas per day, with the infrastructure built to serve three separate destinations depending on national and regional demand.

The Hammerhead field is projected to produce 150,000 barrels of oil per day once operational. Before any gas is exported elsewhere, the first call on output will be the project's own floating production, storage and offloading vessel, named Essequibo 1899. Gas will be used to power the FPSO and its associated equipment, a standard requirement for offshore installations of this type. Only volumes surplus to these operational needs will be routed onward through the new pipeline.

The pipeline itself connects the Hammerhead terminal to the wider offshore gas transportation network. Engineers have incorporated subsea control systems and isolation valves that can be operated remotely from the FPSO, allowing flow to be managed or halted without requiring a vessel or diver to be sent to the seabed. The route has been assessed for seismic activity, ocean current patterns and the stress that temperature variation can place on subsea infrastructure over its operational lifetime. These checks are intended to reduce the likelihood of structural failure in a section of pipeline that will carry gas for a development expected to run for years.

Once gas moves beyond the FPSO's own requirements, three pathways have been identified for its use.

The first is domestic power generation, through the second phase of the Gas-to-Energy initiative. Up to 75 million cubic feet of gas per day could be diverted to a proposed 300-megawatt power plant onshore. This phase would also support increased processing of natural gas liquids, a by-product that has commercial value of its own when separated and refined.

The second pathway involves the Berbice region, where officials have proposed extending gas supply to support industrial expansion. Fertiliser manufacturing and alumina processing in Region Six have both been cited as potential beneficiaries, industries that typically require a reliable and reasonably priced gas feedstock to remain competitive. Extending pipeline capacity into Berbice would mark a shift from purely offshore or single-site domestic use toward broader regional industrial planning.

The third option is transfer to the Unity facility, an existing offshore installation. Gas routed here would support ongoing extraction at the Liza field, one of the earlier developments in Guyana's offshore programme. This pathway effectively allows newer production to sustain older infrastructure, extending the operational life of fields that have already been in production for several years.

Officials have not indicated what proportion of gas will ultimately go to each destination, and the split is likely to depend on demand, infrastructure readiness and pricing agreements that have yet to be finalised. The pipeline's design, however, allows for that decision to be made flexibly rather than fixed at the point of construction.

The Hammerhead development is being carried out by a consortium of three companies. The principal operator holds a 45 per cent stake in the project, with two international energy firms holding the remaining shares, at 30 per cent and 25 per cent respectively. This ownership structure mirrors the arrangement used across several of Guyana's earlier offshore projects, in which a lead operator manages day-to-day operations while partners share in both the investment and the output.

The scale of the Hammerhead project, alongside the flexibility built into its gas distribution network, reflects the growing complexity of Guyana's offshore sector as it moves beyond its earliest developments. With production not due to begin until 2029, the coming years are likely to bring further detail on how gas volumes will be allocated between domestic energy needs, regional industry and the maintenance of existing offshore output.
