Feb 15, 2026 News

(Kaieteur News) – Guyana’s fifth Floating production Storage and Offloading vessel (FPSO), Errea Wittu is making steady construction progress with mooring pre-installation activities now completed.

The scope of work included the installation of suction anchors and the pre-lay of mooring lines in preparation for hookup of the FPSO in the Stabroek Block, offshore Guyana.

Jumbo Offshore, a subcontractor working along with ExxonMobil to complete the vessel recently reported that it performed installation engineering, procurement, mobilisation and marshalling activities to support offshore installation. The offshore campaign was executed using Jumbo Offshore’s J-class installation vessel, Fairplayer. Furthermore, the company said all operations were conducted in accordance with project requirements and applicable safety standards.

The Errea Wittu FPSO will produce hydrocarbons discovered by Exxon at the Uaru project, the fifth deepwater development that is likely for start-up this year. The contract for the construction of the vessel was awarded to Japanese shipbuilder Modec in November 2022.

Project Manager at Jumbo Offshore, Freek Muurling said, “I am very proud of the hard work and commitment shown by all Jumbo personnel and subcontractors during the preparation, mobilisation, and execution of this deepwater pre-lay mooring project. The team demonstrated full focus on engineering, procurement, documentation, and meticulous planning in sometimes challenging circumstances. The yard and offshore teams’ resilience and teamwork led to a safe and successful completion of the mooring line installation campaign”.

He also lauded the transparent and constructive communication between Jumbo, Modec, and Exxon, which created a strong working relationship and contributed to moving the project forward safely and efficiently.

The Uaru field is located 200 kilometres offshore Guyana at a depth of 1,750 metres. It is estimated to hold more than 800 million barrels of oil.

The Errea Wittu FPSO will produce 250,000 barrels of oil per day (bpd) and will have a gas treatment capacity of 540 million cubic feet per day. It will have a water injection capacity of 350,000 bpd, a produced water capacity of 300,000 bpd and a storage capacity of two million barrels of crude oil.

Currently, Guyana is producing about 900,000 barrels of oil per day (bpd) from four FPSOs thar are operating in the Stabroek Block. The startup of the Uaru project will push Guyana’s total production capacity to almost 1.2M barrels per day.

Exxon has already signalled its intention to the government of Guyana to increase production here to 1.7M barrels per day by 2030. So far, the company has obtained regulatory approvals for seven projects. An eight application was made by the company and is currently pending review at the Environmental Protection Agency (EPA).

While sections welcome the new FPSO, the eventual startup of the project will not bring change Guyana’s revenue stream from the sector significantly, as 75 of every 100 barrels will continue to be deducted for cost until the country pays Exxon for all the projects it intend to bring online in the coming years.
