ExxonMobil Guyana Ltd.'s contractor MODEC Inc. delivered the Errea Wittu floating, production, storage, and offloading vessel (FPSO) to integrate the development of the Snoek, Mako, and Uaru resources in Stabroek block, offshore Guyana.

The FPSO will be deployed about 200 km offshore in 1,690 m of water using a spread mooring system. Errea Wittu is expected to produce 250,000 b/d of oil and will have a gas treatment capacity of 540 MMcfd alongside a crude oil storage capacity of about 2 million bbl.

Errea Wittu construction is based on MODEC’s new-built hull design, featuring a full double hull and a larger topsides deck area to accommodate high-capacity processing systems. The vessel is also equipped with a gas-turbine combined cycle system, which helps reduce carbon dioxide emissions and supports more efficient operations.

The FPSO’s advanced design supports future remote operations from shore, while its AI-enabled systems help predict equipment failures, reduce emissions, and enhance process safety insights.

Errea Wittu will undergo final offshore preparations and commissioning ahead of first oil.

ExxonMobil Corp. affiliate ExxonMobil Guyana is operator of and holds 45% interest in Stabroek block. Hess Guyana Exploration Ltd. holds 30% interest, and CNOOC Petroleum Guyana Ltd. holds 25% interest.
