This report documents a project to improve subsea flow measurements to allow the flow rates of individual wells to be known more accurately, thus reducing risk to both producers and the US government while also improving reservoir recovery. In this project, a non-invasive metering approach was adopted using a clamp-on meter that may be conveyed to the sea floor using a ROV. The goal of this project was to develop and prove methods for conveying a clamp-on meter to the sea floor by ROV, and document the results as a draft standard for the future. Meters/sensors were marinized for prototype demonstration in surface multiphase flow loops and in underwater test tanks.
