Maersk Drilling, a unit of A.P. Moller-Maersk, said on Wednesday it had sold its Venezuelan drilling barge activities. “The accounting gain from the transaction is positive for Maersk Drilling, but insignificant for the Maersk Group,” the unit said in a statement, adding that revenues from the Venezuelan barge business amounted to $195 million. Maersk Drilling made a similar announcement on Tuesday but later said the statement had been uploaded erroneously.
