SBM Offshore has completed financing of $1.14billion (£886m) to pay for the vessel which will serve ExxonMobil’s giant Liza field off Guyana.
The Dutch shipbuilder said the loan was secured by a consortium of nine international banks, with SBM expecting to draw it in full over a phased construction period for the floating production, storage and offloading (FPSO) vessel.
Liza Unity will be designed to produce 220,000 barrels of oil per day, with gas treatment capacity of 400million cubic feet per day.
SBM said the FPSO will be able to store around two million barrels of crude oil.
The Liza field lies in the Stabroek block, around 125miles off Guyana.
Operator ExxonMobil, which golds a 45% stake, said the gross recoverable resources estimated from the block, including Liza and other successful exploration wells, exceeds six billion barrels of oil equivalent.
Hess Guyana holds 30% and CNOOC Petorleum Guyana has the remaining 25%.
