Petrobras' PRA-1 Commences Production Ops in Campos Basin

Petrobras announced that Autonomous Repumping Platform PRA-1 started operating on September 22 in the Campos Basin, located in the State of Rio de Janeiro. Designed to receive and transfer oil production from platforms P-51, P-52, P-53, and P-55, the PRA-1 is capable of transferring up to 818,000 barrels of oil per day.

The first oil to be transferred will come from the P-52. This oil is currently pumped to FSO Cidade de Macae, a storage vessel, from where it is offloaded to relief vessels via transfer operations. According to logistics needs, as of 2009 this oil may also be transferred through two monofloats which will supply oil tankers.

The PRA-1 is part of one of the most important logistics systems of the Campos Basin: the Outflow and Treatment Master Plan (PDET), which, when in full operation, will offload part of the oil produced in the Roncador, Marlim Leste, and Marlim Sul fields, where four production platforms will be in operation.

Technical Characteristics

The PRA-1 is a fixed platform designed to receive and transfer, via submarine pipelines, a high volume of oil coming from units P-51, P-52, P-53, and P-55. In the future, it will be able to receive oil from four more producer units. The main difference between the PRA-1 and Petrobras' other fixed units is the fact that it does not have an oil processing plant and that it operates as a repumping unit.

Installed in January 2007, it is anchored in the Campos Basin, some 120 km off the coast, at a depth of 106 meters. With 65% national content, the PRA-1 construction work generated six thousand direct and indirect jobs.

With investments in the order of $837 million, it took two years for the autonomous repumping unit to be built in a modular manner. The jacket (the lower part of the platform) was manufactured in Paranagua, Parana, by Techint; the pumping, measurement, utility and housing modules were built at the Sao Roque de Paraguacu construction site, in Bahia, by the Odebrecht/UTC consortium; and the power generation module was manufactured by Rolls Royce, in Niteroi, Rio de Janeiro.
