WEG Motors And Generators Maintain FPU Reliability

WEG has announced that its HV electric motors, inverters and generators have been utilised in the P-53 floating platform unit (FPU) deployed by Petrobras off the coast of Brazil. The company said the FPU relies on WEG's products for its continuous reliable operation in the worst of environmental conditions. The platform uses WEG medium- and high-voltage motors to drive water-injection pumps to pump water into the oil well; this in order to maintain high levels of extraction and avoid internal low-pressure conditions.

WEG motors also drive the pumps used for oil production outflow from the platform, and those responsible for cooling systems on the platform. The compression modules used on P-53 are supplied by DRVA, a consortium of Dresser-Rand and Vetco Aibel. These units also depend on three WEG 13,500kW, four-pole, 6600V, synchronous motors driven by frequency inverters. The motors and inverters were supplied as integrated systems by WEG to Dresser-Rand in the US, and to the oil and gas market in general.

The supply of three compression module motors to P-53 follows the success of three identical WEG motors that are already in operation on the Petrobras P-54 platform. These drive Dresser-Rand compressors, exporting the gas extracted from Module Two of Roncador field, in the Campos Basin in the state of Rio de Janeiro, Brazil. The P-54 project is targeted to provide production of 180,000 barrels of oil, and six million cubic metres of gas per day- the same amount projected for P-53 when it is in full production.

On both platforms, motors supplied by WEG are playing a key role in helping to achieve these targets. In addition to HV motors, WEG has also supplied P-53 with four 28.75MVA WEG generators driven by generation module turbines; a 42-column load centre of 4000A - 65kA (resistant to internal electric arc); and a 49 removable-column MCC.

Specially designed for offshore application, the low-voltage panels will be installed on electric modules P-08 and P-06, all of which have been tested and approved, and are Bureau Veritas certified.
