Jumbo Offshore completes mooring pre-installation for Errea Wittu FPSO

Schiedam, Netherlands-headquartered Jumbo Offshore has completed mooring pre-installation activities for the FPSO Errea Wittu for Exxon Mobil Guyana Ltd. at Uaru Field, Stabroek Block, offshore Guyana.

The scope of work, carried out on behalf of Modec, under a contract awarded in January 2024, included the installation of suction anchors and the pre-lay of mooring lines in preparation for FPSO hook-up.

Jumbo Offshore performed installation engineering, procurement, mobilization and marshalling activities to support offshore installation. The offshore campaign was executed using Jumbo Offshore’s J-class installation vessel, Fairplayer. All operations were conducted in accordance with project requirements and applicable safety standards.

“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,” said Freek Muurling, project manager at Jumbo Offshore. “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.

“I would also like to highlight the transparent and constructive communication between Jumbo, Modec, and Exxon, which created a strong working relationship and contributed greatly 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 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.
