Co.L.Mar has won a new project for ALD: a new success for
us and excellent business for our customer.

A new, 20km pipeline was found to be leaking during the final hydrotest. After adding dye, the ROV visual survey gave no result. ALD was then mobilised ALD which detected the leak during the very first run. At the moment of the detection the differential pressure was lower then 8

The turbulence created by the leak flow generated turbidity in a very wide area, making the visual detection of
the leak impossible.
