Jumbo Offshore has scooped a contract award from MODEC Guyana for the pre-installation of the mooring spread of the FPSO Errea Wittu, due to be installed on ExxonMobil’s Uaru field offshore Guyana.

Errea Wittu will have the capacity to produce approximately 250,000 BOPD and will have gas treatment capacity of 540 MMcf/D, and water injection capacity of 350,000 B/D. The vessel will also be capable of storing 2 million bbl of oil.

The Errea Wittu is MODEC’s first project with ExxonMobil since it delivered floating storage and offloading vessel Kome Kribi 1 in Cameroon for Esso Chad in 2003.

MODEC Group was authorized to proceed with the engineering, procurement, construction and installation (EPCI) scope for the FPSO in May 2023, following a final investment decision on the Uaru project by ExxonMobil Guyana Ltd. and its co-venturers. The FPSO mooring system will be supplied by MODEC subsidiary SOFEC and comprises a total of 19 mooring legs.

Jumbo Offshore will be using its heavy-lift construction vessel Fairplayer, which will allow the transport and installation of the 19 suction anchors, 8800 m of chain sections, and 43168 m of polyester rope in the minimal amount of installation voyages.

Errea Wittu will be the fifth offshore FPSO in Guyana and will combine the development of the Snoek, Mako, and Uaru resources in the Stabroek block. It will be deployed approximately 200 km offshore Guyana, at a water depth of 1690 m.

Offshore Frontier Solution, a MODEC Group company and a joint venture with Toyo Engineering Corp. launched in August 2022, is responsible for the engineering, procurement, and construction of the FPSO based on MODEC’s M350TM newbuild hull.

The vessel is expected to be delivered to ExxonMobil in 2026. First oil from the project is slated for later that same year.

ExxonMobil’s co-venturers on the Stabroek block are Hess Guyana Exploration Ltd. (30%) and CNOOC Petroleum Guyana Ltd. (25%).
