Brazilian state-controlled company Petrobras has launched a tender to contract two new floating production, storage and offloading vessels to serve the Atapu and Sepia pre-salt fields in the prolific Santos basin.

Petrobras invited companies to submit commercial bids on 20 July and is offering engineering, procurement and construction (EPC) contracts for Atapu-2 and Sepia-2, internally labelled as the P-84 and P-85 FPSOs, respectively.

The contracting strategy, under which Petrobras will own and operate both units, is expected to attract some Asian shipyards, although no single company will be awarded the two deals, according to the bidding rules.
