Brazil's Brasdril has fixed Deep Sea Supply and Siem Offshore platform supply vessels (PSVs) for cargo runs.
Deep Sea's 4,700-dwt Sea Brasil (built 2012) and Siem's 4,700-dwt Siem Atlas (built 2013) have been taken for three firm days plus options.
No rates have been revealed, but they will supply the semi-submersible rig Ocean Valor, broker Westshore said.
Meanwhile, CBO's 3,400-dwt PSV CBP Manoella (built 2008) has been released by Statoil as it optimises its fleet in Brazil.
