DNV to Class Petrobras' P-58 FPSO Conversion

A contract has now been signed with Petrobras for classification services for a VLCC tanker conversion into an FPSO, to be named the Petrobras-58, or simply P-58. The P-58 will be the first Petrobras-owned FPSO to be classed by DNV.

P-58 will operate in Parque das Baleias' north fields, Campos Basin, located offshore in Espírito Santo state south coast, and will be spread moored in a maximum water depth of 1,400 meters. The unit will be designed for at least 25 years of uninterrupted operation without the need for dry-docking.

The process plant will have the following capacity:

  • production and treatment of 47,700 m3/day of liquids
  • 28,620 m3/day of crude oil
  • gas compression capacity of 6,000,000 m3/d and
  • de-sulphated water injection capacity of 57,500 m3/day

Oil production will come from 19 satellite wells connected individually to the unit. Water will be injected into 10 satellite wells.

The classification contract for the conversion phase will last for 56 months and includes the design review of the basic design, FEED, detailed design, hull conversion survey, modules fabrication survey, integration and offshore commissioning. The classification services will mainly be carried out by DNV in Brazil, since the design and most of the conversion work will be performed locally.
