ExxonMobil’s Guyana subsidiary, Esso Exploration and Production Guyana Limited (EEPGL) announced that the Liza Unity floating production, storage and offloading (FPSO) vessel has arrived in Guyana’s waters ahead of schedule.
At present production in Guyana is approximately 100,000 barrels per day. With this additional FPSO, production next year is set to triple.
The Liza Unity FPSO is designed to produce approximately 220,000 barrels of oil per day, to have associated gas treatment capacity of 400 million cubic feet per day and water injection capacity of 250,000 barrels per day. The FPSO will be spread moored in water depth of about 1,600 meters and will be able to store around 2 million barrels of crude oil. There are a total of 19 topsides modules.
The vessel will be supported by six drill centres and approximately 30 wells. This includes 15 production wells, nine water injection wells and six gas injection wells.
According to SBM, the Liza Unity FPSO has also been awarded the SUSTAIN-1 notation by ABS, the Classification Society.
This means that the design and construction of the unit is assessed against and adheres to the requirements of the ABS Guide for Sustainability Notations, aligned with the applicable UN Sustainable Development Goals. The Liza Unity is the world’s first FPSO to achieve such recognition for sustainability for its design, documentation and operational procedures. Examples of features recognised by the SUSTAIN-1 class notation include energy efficiency management, mitigation of ozone depleting substances and management of hazardous materials throughout the life cycle.
