Technical system, method and use for online measuring and monitoring of the particle contents in a flow of injection water in an underwater line

Abstract

Technical system and method for online measuring and monitoring of the particle content in an injection water flow (') in an underwater line (). The system comprises a data gathering means, a data communication link () and a data receiving means comprising an image analysis apparatus () provided with: a water sample line () for throughput of a partial flow (″) of the injection water flow (′); a means of conveyance () connected to the water sample line () for transport of the partial flow (″); a light-transparent flow portion (′) disposed along the water sample line (); a camera () at the flow portion (′); at least one light source () for emission of light () via the flow portion (′) and into the camera (); an electronic control means () for (a) control of the image recording of the camera (); (b) reception of image material from the camera (); and (c) transmission of the image material to the data receiving means; and at least one energy supply. The image analysis apparatus () is disposed in a water-tight housing () under water (); wherein the water sample line () is connected to the underwater line () at a connection site () between a shipment site () for the injection water (′) and an injection well (); wherein the data receiving means is located at a distance from the image analysis apparatus (); and wherein the control means () of the image analysis apparatus () is connected to the remote data receiving means.
