D5 DyeTector

Mini subsea leak and dye detection system

The D5 DyeTector is an advanced ultra-compact subsea leak and dye detection system developed for installation on AUV systems or smaller observation class ROVs.

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 D5 DyeTector uses the same technology capable of detecting single photons of light as larger DyeTector units. This enables it to detect down to single digit parts per billion of dye dissolved in water and 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.

The D5 DyeTector has been specifically designed for installation on AUV systems, with free-running data and low-power electronics to reflect the increasing use of AUVs for pipeline surveys. It can also be deployed on smaller observation class ROVs, with simple and intuitive DyeTection software to display detection data at the surface.

 

Key Features:

  • Rhodamine, Fluorescein or Ultraviolet dye detection

  • Compact design for AUVs or small ROVs

  • Same powerful DyeTector technology as larger units

  • Configurable serial control or free-running data output

  • 1000m standard depth rating

 

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.

 

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 meters depending on the concentration of dye.

Detection dyes

Versions of the DyeTector are 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
