Brazilian tanker owner Transpetro is preparing tender papers for 21 newbuildings after launching a hunt for four tankers aimed at fleet renewal.

The tanker and terminal operating subsidiary of government-controlled oil giant Petrobras told TradeWinds it is targeting 25 vessels under its TP 25 expansion and renewal programme.

The contracting efforts will build on a just-launched tender for a quartet of handysize clean product tankers, in which the shipowner invited international yards to compete with Brazil’s shipbuilding sector.
