Head of Sales Upstream Industries, Holger Wörner sees an increasing demand for this small-footprint compressor technology. It is hermetically sealed, oil-free and employs seven-axes active magnetic bearings, so it dispenses with many components typically requiring maintenance in conventional topside compressor systems including gear- box, lubrication-oil system, instrumentation and valving.

Virtual sensors allow operators to validate measured data in real time, increasing operational effciency and ac- curacy while, leveraging machine learning capabilities, the system also continuously improves performance over time.

Digitalization is also helping optimize the faring pro- cess. With Baker Hughes’ emissions abatement technol- ogy, fare.IQ, bp is using critical information from its fare systems, including temperature, pressure, vent gas veloci- ties and gas composition, to help maximize combustion effciency and minimize emissions. Acting on real-time

Growing interest in measurement-based reporting network purge, and some provision for fugitive emissions is evident in the growth in OGMP membership which has are also accounted for. The result will be a reduction of about 50kT of CO2 per year or 1,250kT CO2 over the doubled to over 120 companies since its launch in 2020.

TotalEnergies has used AVEVA’s PI System to create a full operating life of the FPSO.
