Dutch oil and gas platform leasing company SBM Offshore has started the topside integration phase on the floating production storage and offloading (FPSO) vessel ‘Liza Unity’ in a yard in Singapore.

Liza Unity FPSO will be capable of producing 220,000 barrels of oil per day (boed). It will have an associated gas treatment capacity of 400 million cubic feet per day (mcfd) and water injection capacity of 250,000 barrels per day (bpd).

The vessel will be spread moored in water depth of around 1,600m and will have the capacity to store more than two million barrels of crude oil.

According to SBM, the mooring and riser system integration and other work were completed at Keppel FELS’ dry dock.

Upon completion, the FPSO will be deployed at Stabroek block in Guyana and become second FPSO in production for the Liza project in Guyana.

The Liza prospect is located approximately 120 miles (193km) offshore Guyana in the Stabroek block, which is operated by ExxonMobil affiliate Esso Exploration and Production Guyana. It is spread over an area of 26,800km² (6.6 million acres) offshore Guyana.

In a press statement, SBM Offshore stated: “Both Keppel and Dyna-Mac shipyards are fabricating the topsides modules for the Liza Unity FPSO.

“This FPSO represents SBM Offshore’s first Fast4Ward design, benefitting from standardisation of the project’s execution plan and using a fully completed and commissioned MPF hull, which sets the benchmark for future FPSO projects.”

SBM Offshore noted that the latest milestone aligns with the Liza Phase 2 project schedule, which targets departure of the FPSO to its final location at the Liza field next year.

The start-up is anticipated for 2022.

In October last year, SBM Offshore completed the project financing of Liza Unity for a consideration of $1.14bn.
