Japanese vessel builder MODEC recently conducted the first steel-cutting ceremony for the Guyana-bound floating production and offloading storage (FPSO) vessel, Errea Wittu, in China.

The FPSO is being used for the Uaru field development which is ExonnMobil’s fifth development in the Stabroek Block offshore. The ceremony followed the commencement of steel cutting for the topside modules in Singapore.

MODEC had secured the FPSO order from the ExxonMobil-led consortium in May 2023 for deployment to the Stabroek block. The construction involves China’s DSIC making the hull and Bomesc Offshore Engineering and DynaMac for the topside modules.

President and Chief Executive Officer (CEO) of MODEC in Singapore, Soichi Ide, expressed gratitude to ExxonMobil for choosing MODEC for this project, highlighting their successful track record in project deliveries.

The Errea Wittu FPSO will play a crucial role in developing the Snoek, Mako, and Uaru resources in the Stabroek block, situated approximately 200 kilometers offshore Guyana.

Operating at a water depth of 1690 meters, it will use a SOFEC Spread Mooring System and have a storage capacity of around two million barrels of crude oil. ExxonMobil’s co-venturers on the Stabroek block include Hess Guyana Exploration LTD (30%) and CNOOC Petroleum Guyana Limited (25%).

The FPSO’s topside is being designed to produce approximately 250,000 barrels of oil per day, with gas treatment, water injection, and produced water capacities specified for optimal operations. MODEC will not only supply the Errea Wittu FPSO but also provide ExxonMobil with operations and maintenance services for 10 years from its first oil production.
