The P-61 platform was completed on Tuesday at the BrasFels shipyard in Angra dos Reis (RJ), Petrobras announced, and left for the Papa-Terra field in the Campos Basin. The Brazilian company has described the unit as an “innovative solution” crucial to developing one of the “most complex projects” ever undertaken by the oil giant.

 

This is the first tension leg wellhead platform (TLWP) built and operated in Brazil. The TLWP model is similar in many ways to a semisubmersible, Petrobras said, with the exception of its mooring system, which relies on vertical tendons of mooring lines. The deck and four modules were built in Singapore and brought to the BrasFels shipyard, which built the hull and was responsible for integrating the unit’s various components.

 

The P-61 will join the P-63 FPSO unit which started oil production in Papa-Terra on November 11. The units will have a combined production capacity of 140,000 barrels of oil per day from 18 wells. The P-63 will process, store and offload all oil produced by the P-61 to shuttle tankers.

 

The Papa-Terra field is located 110 km off the Brazilian coast and is operated by Petrobras (62.5 per cent) in partnership with Chevron (37.5 per cent). In water depths of 400-1,400 meters and containing heavy oil reservoirs with an API gravity between 14 and 17, it is one of the most challenging projects ever conceived by Petrobras, the company stated, and the P-61 is set to go a long way towards overcoming those challenges.
