Oslo-listed FPSO group BW Offshore is "contemplating" buying a Brazilian oil field from Petrobras and Chevron.
It said the move would see it acquire 100% of the Maromba field. Petrobras currently owns 70% and Chevron the rest.
A deal would have to be approved by the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP).
No price has been revealed for the transaction.
The field is in the Campos Basin in 160 metres of water, where BW Offshore has extensive operating experience.
In January, the company secured a one-year extension for its 257,865-dwt FPSO Polvo (built 1980, converted 2007) with PetroRio until the third quarter of 2020.
It is one of BW Offshore's 15 vessels and the second working in Brazil.
The diversification echoes that of sister company BW LPG, which said last week that it would be forming a new division to buy LPG to boost use of its vessels.
