The ALD system in ROV and diver version is equipped with an additional channel which can now host a hydrocarbon detector: the Turner Design – Cyclope 7. The sensor detects crude oil with a minimum detection limit of 0.1ppm. It is now possible to run an acoustic and optical inspection of the pipeline simultaneously.
Leak simulator
CO.L.MAR has recently completed the supply of a underwater leak simulator. The system simulates liquid and gas leaks within a wide range of differential pressure and leak sizes. The on-site conditions can be replicated and the acoustic signal generated measured and used as a precise target reference.
