The hull for SBM Offshore’s Prosperity floating production, storage and offloading vessel — which will be deployed at ExxonMobil’s Payara field offshore Guyana — has arrived safely at Keppel Shipyard in Singapore.

The next construction phase for the newbuild floater will see the topsides modules being integrated at the yard.

“Despite the various challenges posed by the ongoing global pandemic, the unit remains on schedule to be completed in 2024,” SBM said on Thursday.

“Drydock activities are scheduled to begin in the fourth quarter of this year, with the installation of major structures that will support the mooring and subsea risers.”

Keppel Offshore & Marine in November late last year won an approximate S$100 million (US$74.7 million) contract for a mystery floater, which Upstream reported appeared to be the FPSO Prosperity.

The hull of the Prosperity was constructed by Chinese yard Shanghai Waigaoqiao Shipbuilding under SBM’s Fast4Ward concept.

Keppel’s workscope includes the fabrication, installation and integration of topsides modules, riser balconies and spread-mooring support structures, as well as supporting the customer on pre-commissioning and commissioning work.

It is understood that Dyna-Mac in Singapore was also tasked with some of the topsides modules fabrication.

The Prosperity FPSO will be capable of producing 220,000 barrels per day of oil, with associated gas processing capacity for 400 million cubic feet per day.

“With the challenges posed by Covid-19, the health and safety of our workforce is paramount. We have put in place measures to safeguard our people and maintain our operations to ensure that each project entrusted to us is delivered as planned,” Keppel O&M’s managing director (conversions and repairs), Chor How Jat said earlier.

Standardisation philosophy

SBM noted that in keeping the standardisation philosophy that guides its Fast4Ward programme, the Prosperity FPSO "by and large" replicates the design used for the earlier Liza Unity FPSO.

“This approach has showcased the value of Fast4Ward, ensuring that the final product is delivered faster to our client ExxonMobil. Once installed, the vessel is intended to produce roughly 220,000 bpd of oil and will be able to store around 2 million barrels of crude oil,” said SBM.

Once completed, Prosperity will join her sister vessel Liza Unity — also under construction at Keppel Shipyard — and the FPSO Liza Destiny, operational since the end of 2019, offshore Guyana.

Partnered by Hess and CNOOC Ltd, ExxonMobil has discovered more than 9 billion barrels of oil equivalent on the prolific Stabroek block, starting with the breakthrough Liza find in 2015.
