Petrobras, a state-owned oil and gas company in Brazil, has chosen a company based in North Carolina to supply a seal-less canned motor boosting system for their field in the Campos Basin. This will help to facilitate reliable subsea production.

Curtiss-Wright Corporation has partnered with Petrobras to design, manufacture, test, and provide operational support for a subsea canned motor boosting system, which will be deployed mudline at a Petrobras production field in the Campos Basin offshore Brazil. The goal is to develop a subsea boosting system for unprocessed hydrocarbon fluid at a 1,500-meter water depth.

Curtiss-Wright is conducting the design, manufacturing, and water-based testing at its Cheswick, Pennsylvania, facility within its Naval & Power Segment. Multiphase testing with hydrocarbons will take place at a facility in Brazil. The first subsea canned motor boosting system is expected to be ready for operation in 2027.

This new technology is designed to enable reliable subsea production while requiring fewer topside support systems. It will also provide flexibility to deploy these systems on lighter-weight, lower-cost vessels, which are more readily available than the larger handling vessels required in today’s operations.

The canned motor pump technology is expected to be a key component in Petrobras’ objective of all-electric subsea boosting systems to enable long tie-back production arrangements. Furthermore, the design provides flexibility to deploy future Curtiss-Wright topside-less subsea boosting systems scalable to 6 MW for multiphase applications, in alignment with Petrobras’ technology development roadmap.
