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