The Liza Unity is the second FPSO built for the ExxonMobil-operated Liza field development in the Stabroek block.
Mooring, hook-up, and commissioning operations will now start. First oil is expected in 1Q 2022.
The Liza Unity is designed to produce about 220,000 b/d of oil, to have associated gas treatment capacity of 400 MMcf/d, and water injection capacity of 250,000 b/d. It will be able to store around 2 MMbbl of crude oil.
It is also the first FPSO to receive the SUSTAIN-1 notation from ABS.
The Liza Unity is SBM Offshore’s first Fast4Ward FPSO, which incorporates the company’s newbuild, multi-purpose hull combined with several standardized topsides modules.
The Prosperity, engineered to produce around 220,000 b/d and to store close to 2 MMbbl, largely replicates the design used for the Liza Unity.
Payara, the third development in the Stabroek block, is expected to start-up in 2024.
