Jumbo Offshore has completed mooring pre-installation activities for the FPSO Errea Wittu at Uaru field, Stabroek block, offshore Guyana for Exxon Mobil Guyana
The scope of work, conducted on behalf of Modec, 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, mobilisation and marshalling activities to support offshore installation, using Jumbo Offshore’s J-class installation vessel, Fairplayer.
“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."
Muurling also highlighted the effective communications 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 and is estimated to hold more than 800 million barrels of oil. Production is expected to begin this year.
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 350,000bpd, a produced water capacity of 300,000bpd and a storage capacity of two million barrels of crude oil.
Guyana is seeing its offshore sector expand rapidly, which in turn is spurring significant economic growth in the country. According to Finance Minister Ashni Singh Singh, whose remarks when presenting the nationa's annual budget were reported by Reuters, the oil sector is set to grow 17.9% this year. He forecast 309 crude oil cargo exports, up from 260 last year, and estimated oil revenue of about US$2.79bn.
ExxonMobil Guyana Limited and its Stabroek block co-partners, Hess Guyana Exploration Limited, and CNOOC Petroleum Guyana Limited are progressing several offshore developments in Guyana’s offshore Stabroek Block. The consortium reached a new production milestone of 900,000 bopd in November 2025, following the ramp-up of Yellowtail, Guyana’s fourth offshore project, and excellent operating performance from other assets. Once its other four planned developments are in production, ExxonMobil Guyana expects to have total production capacity of 1.7mn bopd.
