OceanTools D7 DyeTector®

The D 7 DyeTector is state of the art subsea leak and cement dye detection system developed by OceanTools based on many years of experience detecting subsea dyes.



The ROV mounted D 7 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, or during casing cementing operations to detect cement returns.

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.
