Seabed levelling towage plays a vital role in preparing marine environments for safe navigation, construction, and anchorage.
At Polaris Marine Group, our specialist towage services are used to level seabeds efficiently and accurately, ensuring uniform depth and removing natural or project-related obstructions.
From harbours and marinas to large port developments, our seabed levelling capabilities support safe, navigable, and construction-ready waters.
What Is Seabed Levelling Towage?
Seabed levelling towage is the process of dragging specialised equipment, such as levelling blades or ploughs, across the seabed using a tugboat or workboat.
This technique is used to redistribute material on the seafloor to achieve a smoother, more consistent profile. It is particularly useful in post-dredging clean-up, berth preparation, channel formation, and the removal of high spots or shoaling.
Why It's Needed
In any port or marine infrastructure setting, an uneven or obstructed seabed poses serious challenges. High spots can limit vessel access, cause grounding risks, and interfere with piling or construction work.
Sediment build-up from tides, river inputs, or dredging works can quickly alter conditions. Seabed levelling is a cost-effective and non-intrusive way to return the seabed to its intended depth without extensive re-dredging or disruption.
How Polaris Marine Group Delivers
Polaris Marine Group uses dedicated tugboats equipped with custom-built levelling ploughs to deliver high-accuracy seabed levelling towage. Our team assesses the site’s hydrographic data and sediment characteristics before developing a towage pattern that delivers uniform coverage. GPS-guided towing paths ensure consistent results, and post-levelling surveys confirm the seabed is within the desired tolerance.
We often work in tandem with dredging operations—either cleaning up after dredge passes or fine-tuning depths where precision is required. Our seabed levelling services are also called on for berth reinstatement, approach channel smoothing, or to prepare laydown areas for marine infrastructure.
Suitable for Diverse Environments
Seabed levelling towage is suited to a wide range of underwater conditions, including silt, sand, and soft clay. It can be deployed in confined urban waterways, deep harbours, and remote marine zones.
Our vessels and equipment are highly mobile and adaptable, allowing us to quickly respond to client requirements anywhere along the Australian coastline.
Environmental Considerations
Seabed levelling towage is considered a low-impact method compared to more intrusive mechanical dredging. It does not remove material from the marine environment; instead, it redistributes it to eliminate high spots.
This method generates less turbidity and is ideal in areas where marine flora and fauna must be protected. Polaris Marine Group also monitors for sediment movement, turbidity, and ecological impact where required.
Integrated Marine Services
Our seabed levelling towage services are often delivered as part of a broader marine works package.
Whether your project includes berth dredging, piling, pontoon installation or seabed preparation for a pipeline or cable lay, Polaris Marine Group can provide the levelling services required to ensure a smooth, safe seabed profile.
By combining this service with our marine plant, engineering and project management capabilities, we streamline delivery for complex jobs.
