Bed Levelling

Seabed levelling is a modern day dredging technique used in many ports and harbours. A plough is towed behind a tug along the seabed levelling high spots and ridges, moving the material to near by low spots. Also built up material can be removed from berths and other inaccessible areas into the tidal stream or operating area of a trailer suction dredger. Material is relocated from one place to another along the seabed and the sediment is not raised from the surface of the water.

Since the bucket dredger departed Shoreham Port in the early 1990’s our harbour tug Adurni has been fitted with a plough for seabed levelling.  We have kept the berths to the charted depths and dedicated ploughing will level shoaling areas. Sediment can be relocated from inaccessible and confined places to deeper areas prior to maintenance dredging. The plough has proven itself as an efficient dredging tool, cutting the amount of tides a trailer suction dredger is required.                        

We are also able to monitor our progress and survey the finished product if requested with our onboard survey equipment.

The plough is fitted with teeth to cut into the seabed material and is very efficient in moving material over short distances. The shorter the distance, the quicker the turn round time, the more material is removed per tide. Types of material that can be moved by seabed levelling are clay, sand, silt and gravel.  The more cohesive the material the more power the tug will need to relocate it.

Bed levelling along side a trailer suction hopper dredger improves the efficiency of the dredger. The peaks the hopper dredger produces can be levelled; this ensures that the draghead is always fully in the bed material.
