SolstadFarstad has fixed an anchor-handler in Brazil for up to four years.
The Norwegian owner said Queiroz Galvao Exploracao E Producao has taken the 165-bp BOS Turmalina (built 2006) for two firm years.
The ship will support installation and production of the BS-4-Atlanta early production system in Brazil.
The work begins in September and the charterer can extend the contract for another two years.
