SBM Offshore has received a statement of maturity from ABS for its seawater intake riser technology, developed with Shell for FPSO applications.

The endorsement followed ABS’ new technology qualification program, which assessed the prototype design. The statement confirms that the technology has passed testing and validation and can be considered for use in a production unit.

The system is designed to bring colder seawater from around 700 m below the ocean surface to an FPSO’s topsides for cooling. Depending on project conditions, it can support onboard process cooling and power generation.

By using colder seawater, the technology is intended to improve energy efficiency, reduce fuel gas use and lower greenhouse gas emissions from offshore oil and gas production.

ABS said completion of the prototype validation stage reflected its cooperation with SBM Offshore and its focus on engineering safety for future offshore energy infrastructure.

SBM Offshore said the technology began as an internal concept in 2014 and was developed through a multi-year program involving Shell and academic research support.

The statement follows a six-month prototype qualification campaign in 2025, witnessed by ABS, Shell and Petrobras. The project was supported by Shell Brasil under Brazil’s ANP research, development and innovation investment clause.

Shell Brasil said the results point to potential optimization and performance gains for FPSO process and utility plants, while supporting decarbonization in offshore oil and gas production.

The milestone comes shortly after SBM Offshore secured work with Petrobras for two FPSOs planned for the Sergipe Alagoas Basin offshore Brazil.
