Petrobras transportation subsidiary Transpetro is to rebid eight 30,000 dwt product tankers. A new solicitation will go out by the end of this month after Transpetro could not conclude contracts awarded to Brazilian shipyards Rio Nave and Estaleiro Maua under an earlier solicitation. Rio Nave, which was to have built five of the ships, could come up with all the documentation demonstrating that it could meet Transpetr's technical and financial requirements. Estaleiro Mau and Transpetro could not agree on a final price for the other three. All eight ships are required to be built in Brazil.
