DRAGFLOW Trench system includes multiple Hydraulic Pumps attached to a steel frame with a protective shield. This symmetrical and reversible system uses a special version of our classic HY85 pump, modified for increased performance. The solution is unique and can be used in different ways according to specific needs.
Every pump is assisted by two attached Hydraulic Excavators.
The Trench can be used to pipe maintenance in off shore project.
It can be easily moved along the whole length of the pipes lying on the seabed, to complete the sand extraction. Once the maintenance is over, the same equipment will put the sand back to cover the pipes.
