* Platform listed 3 degrees after fire, drilling-fluid leak
* No workers aboard the platform were injured-Petrobras
RIO DE JANEIRO, March 13 (Reuters) - Brazil's state-controlled oil company Petrobras said on Tuesday that it suffered a fire and drilling-fluid leak aboard an offshore drilling rig in the Albacora Field northeast of Rio de Janeiro.
The platform listed as much as 3 degrees from normal after the accident, Brazil's energy regulator, the ANP said. The fire was controlled immediately, the platform stabilized and none of the 102 workers aboard the Alaskan Star rig were injured, Petrobras said in a statement.
The platform, also known as the SS-39, was built in Japan in 1976 according to an oil rig tracking website Rigzone, and is operated for Petrobras by Brazil's Queiroz Galvao.
The Albacora Field, one of Rio de Janeiro-based Petrobras' largest, is in the Campos Basin, an offshore area responsible for about 80 percent of Brazil's oil output.
Petrobras said it is conducting an investigation and that the well connected to the platform was closed as a security measure and that no oil had leaked into the ocean.
While no oil was spilled, a "small" quantity of drilling fluid, a liquid used to help bore through rock, had been leaked, the ANP said in a statement.
Queiroz Galvao officials could not be immediately reached for comment.
