In a significant step forward for subsea technology, NOV and Petrobras have signed a pre-commercial agreement to develop flexible pipelines capable of withstanding extreme CO₂ conditions in deepwater. This collaboration focuses on solving the challenge of stress corrosion cracking (SCC), a persistent problem in subsea oil and gas operations, by incorporating stainless steel armor.
Flexible pipes and their impact on the petroleum industry
The signing of this agreement, which took place in February 2025, marks a breakthrough for the energy industry. Petrobras will invest in the development and certification of this new technology, while NOV will utilize its expertise in flexible pipes to ensure that the proposed solutions are both innovative and practical.
The collaboration will focus on developing risers and gas injection and production flow lines that can handle elevated CO₂ levels. The goal is to provide a corrosion-resistant solution that addresses cracking issues while retaining the key features of traditional flexible pipes , such as ease of installation and compatibility with existing infrastructure.
This agreement, in addition to benefiting Petrobras, represents a breakthrough for the entire oil and gas industry, demonstrating how collaboration between major players in the sector can drive the development of advanced technologies for extreme subsea conditions.
