D7 DyeTector

Single digit parts per billion dye detection

  • ROV mounted or Diver Held versions

  • Rhodamine, Ultraviolet or Fluorescein dye detection

  • Focused beam and filtered high intensity LEDs

  • Light amplification and photon detection technology

  • Depth ratings of 400m, 4000m and 8000m

The D7 DyeTector is a truly state of the art subsea dye detector. High-power LED light is focused through lenses and filters to create a very narrow high energy 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 in order to detect the fluorescing dye.

The D7 DyeTector uses a new technology capable of detecting single photons of light, 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.

For larger leaks, we offer the D3 and D5 DyeLighter range.

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.

Cement detection

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.

Detection dyes

Versions of the D7 DyeTector are designed to detect specific types of dye in addition to OceanTools C-Dye and C-Dye 370, including:

  • Rhodamine dyes such as B275, RX9022, Pelagic 100 Pink

  • Ultraviolet dyes such as RX9026E, Pelagic 100, Champion Cleardye, Castrol HT2

  • Fluorescein dyes such as HW443, HW540P, Oceanic Yellow LTF
