Available to rent from Ashtead Technology – the OceanTools D8-DyeTector dual channel subsea dye detection system

The D8 DyeTector is an advanced subsea leak, dye and cement detector developed by OceanTools to detect Rhodamine and Ultraviolet dyes using a single compact ROV mounted Device The ROV mounted D8 DyeTector has two sets of optical components, configured to detect both C Dye 530 or other rhodamine dyes and C Dye 370 or other ultraviolet dyes. One set of optics is activated at a time, so that rhodamine or ultraviolet dyes can be detected in isolation. High intensity LED light is focused through lenses and filters to create a concentrated beam that is tuned to a specific wavelength to cause maximum molecular agitation and fluorescence of the dye.

A sophisticated optical multiplier employs light amplification technology to detect fluorescence from the agitated dye molecules. Advanced detection electronics convert the measurements to digital data. The powerful DyeTector technology is capable of detecting single photons of light It can detect down to single digit parts per billion of dye dissolved in water and is approximately one hundred times more sensitive than the human eye This makes it ideal for detecting the very smallest of leaks or traces of dye dosed cement. Detection can be carried out at a safe working distance.

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. The DyeTector is machined from aviation grade titanium and sapphire glass to give it a standard depth rating of 4000 metres. Simple and intuitive DyeTection software is used to select the required dye detection optics, display detection data at the surface, and record data for future analysis.

  • Dual channel subsea dye detection system
  • Rhodamine and Ultraviolet dye detection
  • Focused beam and filtered high intensity LEDs
  • Light amplification and photon detection technology
  • Compact alternative to using separate detectors
  • 4000m standard depth
  • 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, if dye impregnated fluids are used
  • Detect cement returns during casing cementing operations, using a tracer dye is added to the seawater spacer or to the cement, from a distance of several metres (depending on dye concentration)
