Eni has cut first steel on the floating production, storage and offloading vessel that will serve its West African deepwater development, Upstream Online reports.

The steel-cutting milestone moves the project from the engineering and procurement phase into fabrication. For an FPSO program, that transition is the first hard confirmation on the ground that schedule commitments made at sanction are being executed — yard slots booked, plate ordered, welders mobilized.

First steel typically precedes hull integration by a margin of 24–36 months on vessels of this class, depending on whether the unit is a newbuild or a conversion of an existing tanker. Eni has not yet stated in the reported material which route the West African unit follows, nor the vessel's designed production capacity in barrels per day.

Eni's West African portfolio gives the project several possible anchor points. The company operates across the Congo Basin — including the Marine XII hub offshore Republic of Congo, where it has deployed a sequence of converted FPSOs tied to FLNG and oil production — as well as interests offshore Ghana, Ivory Coast, and Angola. Upstream's report identifies the vessel only as Eni's West Africa FPSO; the company has not confirmed in the cited material which license the unit will serve.

Watch for the follow-on milestones that will define the project timeline: keel laying, topsides module integration, sail-away from the fabrication yard, and the arrival and hook-up window on station offshore. Each step narrows the startup range, and first oil from an FPSO of this type generally follows station arrival by three to six months of commissioning.

The margin to watch is Eni's schedule discipline. West African FPSO programs have historically faced slippage at the integration and commissioning stages rather than at first steel; the industry-wide metric that matters now is months from steel cut to first hydrocarbons, and whether this program holds inside a three-year envelope.
