Topsides lifting for the ExxonMobil-commissioned 220,000-b/d Liza Unity floating production, storage, and offloading (FPSO) vessel has finished at Keppel Shipyard in Singapore. System integration and onshore commissioning are the next steps in the FPSO’s construction, after which it will depart for station at Liza field in Stabroek block offshore Guyana.
Liza Unity is the first FPSO to be built using SBM Offshore’s Fast4Ward standardized design and execution plan, based on a fully completed and commission multipurpose floater (MPF) hull. SBM says the project remains on schedule for first oil in 2022.
Liza Unity moved out of drydock fourth-quarter 2020 following mooring and riser system integration. Keppel and Dyna-Mac shipyards fabricated Liza Unity’s topsides modules.
ExxonMobil last year increased its estimated recoverable resource base in Guyana to 8 billion boe from 6 billion boe. The company has 16 discoveries in Stabroek block. It also last year advanced development of its third Stabroek field, Payara, using another SBM MPF-based FPSO (OGJ Online, Oct. 1, 2020).
