Petrobras Joins Hull and Topsides for P-51 Platform

On Saturday, April 19th, Petrobras completed the deck mating procedure for platform P-51, the first semisubmersible platform built entirely in Brazil. Deck mating is a huge operation carried out to join the unit's hull to its topside. This maneuver was carried out in one day at the BrasFels shipyard, in Angra dos Reis RJ, proving Brazilian naval engineering capacity and Petrobras' technology for deepwater production projects.

With investments of approximately $830 million, the P-51 was built by the FSTP (Keppel Fels and Technip) consortium in the cities of Niteroi, Rio de Janeiro, Itaguai, and Angra dos Reis. Today, after deck mating completion, the platform will enter its final construction and integration phase at the BrasFels shipyard, in Angra. Its hull was the first to be built in Brazil for a semisubmersible platform. The job has already surpassed the minimum national content requirements, at a rate of nearly 70%, and generated more than 4,800 direct jobs.

The platform is expected to leave the BrasFels shipyard towards its installation site in September and to kick off operations late this year in the Marlim Sul field, in the Campos Basin. The unit will be able to process and treat 180,000 barrels of oil and 6,000,000 cubic meters of gas, and to inject some 45,000 cubic meters of water in the reservoir per day.

Even after platform P-51 sails away to its location, another 4,800 jobs will be generated with the construction work for P-56. This new platform will be a clone of the P-51 and is expected to go online, also in the Campos Basin, in 2010. The same companies in charge of building the P-51 were hired to construct the P-56, since one project is a copy of the other. This will allow production to be anticipated at Marlim Sul.
