OceanTools D10 DyeTector is an advanced subsea leak, dye and cement detector developed with three sets of optical components to detect the three primary dyes used for underwater detection – rhodamine, ultraviolet and fluorescein – using a single compact device.

High-power LED light is focused through lenses and filters to create a concentrated beam that is tuned to a specific wavelength to cause maximum fluorescence of the dye. Detection electronics employ clever light amplification technology to amplify even the smallest amounts of fluorescence from the agitated dye molecules.

The powerful ROV mounted D10 DyeTector uses the same technology capable of detecting single photons of light as the single channel D7 DyeTector, which enables it to detect down to single digit parts per billion of dye dissolved in water. This makes it ideal for detecting the very smallest of leaks or dye dosed cement.

Advanced ambient light suppression technology allows the DyeTector to be used in high levels of background light and also means the ROV’s lights do not need to be turned off.

Subsea infrastructure

A DyeTector may be used to detect leaks from subsea infrastructure such as manifolds, wellheads or pipelines if a suitable dye has been added to the infrastructure fluids. Pipeline or flow line pressure testing can be monitored by the DyeTector if dye impregnated fluids are used.
