Dredging
Dredging depth of Optimus can be anything between
3 - 29 m
Wasa Dredging Backhoe Dredgers are highly specialized for dredging both soft and harder soils. The backhoe dredger is the preferred tool to dredge in protected water, especially in hard soils and for dredging blasted rock. Large units such as big boulders can be handled. The backhoe dredger has the capability of working in shallow waters or even dredge its own water depth if needed. Limited manoeuvring space near quay walls, breakwaters and such is not a problem for this versatile piece of equipment.
The Wasa Backhoe Dredger (BHD) can quickly be optimized for the task at hand. WD dredgers have a wide range of equipment available such as boom and stick configurations and different bucket sizes and types. For example the dredging depth of “Optimus” can be everything in between 3 and 29 meters. The buckets can be changed ranging from light-weight loose soil 22 m3 buckets to hard material 9 m3 buckets to environmental buckets. The pontoon itself has been formed by the experience Wasa Dredging has gained throughout its existence. An example of this is the spud system which is optimized to be one of the fastest systems in the world for moving the backhoe dredger
