Maria Quitéria Project in Brazil | Topside Design, Flow Assurance & Mooring Analysis

The Maria Quitéria Project is a pre-salt offshore oil development located in the Santos Basin, Brazil. As part of Petrobras’ ongoing efforts to expand production from Brazil’s ultra-deepwater reserves, this project involves the deployment of a new-generation Floating Production Storage and Offloading unit (FPSO) connected to a network of subsea wells. NWE has been engaged in the project primarily to provide specialized inspection services, ensuring equipment and materials meet strict quality, safety, and regulatory standards across multiple international fabrication and integration sites.

Project Description

5
(1)

The Maria Quitéria field is part of the broader pre-salt cluster development strategy in the Santos Basin, approximately 200 km offshore Brazil in water depths of around 2,000 meters. The FPSO Maria Quitéria will have a production capacity of approximately 100,000 barrels of oil per day and will be equipped to process associated gas and reinject CO₂, in line with Petrobras’ low-carbon strategy.

The field development involves subsea wells, flexible risers, umbilicals, and tie-ins to the FPSO. The FPSO is being converted and integrated at international yards before final commissioning and deployment offshore Brazil.

Provided Services

For this project, NWE is providing:

  • Third-party inspection of topside modules, pressure vessels, piping systems, and structural components at fabrication yards mainly in Norway.
  • In-depth welding inspections, NDT evaluations, and coating verification at critical stages of fabrication.
  • Electrical and instrumentation component inspections prior to shipment and integration.
  • FAT witnessing for major equipment packages including compressors, separators, and power systems.
  • Quality surveillance to ensure dimensional accuracy, mechanical integrity, and vendor compliance.
  • Support for punch listing, certification tracking, and document control to align with project quality requirements and international standards.
