Diver held subsea dye detection system

OceanTools DyeTector is a state of the art subsea leak and dye detector. 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 diver held D9 DyeTector is a self-contained unit featuring ruggedised single switch operation, a built-in detection display and a depth rating in excess of 250m. The unit is ideally balanced with centre of gravity at the front face of its ergonomic handle. It can be powered using an external portable battery pack via a tidy cable that exits from the end of the handle near the operator’s wrist.

The D9 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.

Key Features:

• Rhodamine, Fluorescein or Ultraviolet dye detection

• Focused beam and filtered high intensity LEDs

• Light amplification and photon detection technology

• Diver operated with 250m+ 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 metres 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
