RIO DE JANEIRO (Reuters) -- Brazil’s state oil company Petrobras started up a new 180,000 barrel-per-day rig Tuesday night on the heavy oil Roncador field after several months of delays, a company spokeswoman said Wednesday.

It is the second rig with that capacity to start working on Roncador in the past two weeks, and the third platform to go on stream since Nov. 16, when Petrobras cranked up the 100,000 bpd rig on the light oil Golfinho field.
All the rigs have suffered delays due to problems with suppliers in an overheated market as well as the complexity of the projects. The rigs should reach capacity by the end of the first half of next year.
