The contracts for three floating drilling rigs include a three-year deal for the ultra-deepwater semisubmersible Ocean Valor, a three-year deal for the deepwater semisubmersible Ocean Baroness, and a five-year deal for the deepwater drillship Ocean Clipper.
Diamond also said Petrobras will use the Ocean Courage in Brazil late in the second quarter, rather than in the Gulf of Mexico as previously planned.
