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.
Key Features:
Rhodamine, Fluorescein and Ultraviolet dye detection
Focused beam and filtered high intensity LEDs
Light amplification and photon detection technology
4000m standard depth rating
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.
A DyeTector may also be used during casing cementing operations to detect cement returns if a tracer dye is added to either the seawater spacer or to the cement itself. Unlike pH meters which rely upon the cement passing over them, a DyeTector can detect cement from a distance of several metres depending on the concentration of dye.
The D10 DyeTector is designed to detect several types of dye or fluid in addition to C-Dye 530 (Rhodamine) and C-Dye 370 (Ultraviolet) including:
Rhodamine dyes such as B275, RX9022, Pelagic 100 Pink
Fluorescein dyes such as HW443, HW540P, Oceanic Yellow LTF
Ultraviolet dyes such as RX9026E, Pelagic 100, Champion Cleardye, Castrol HT2
