Reduce your dredging costs by 20-50%

The most accurate solution for supporting port expansion and operability

Increases in vessel sizes are part of the future. Modern ports will need to be ready for this change to stay competitive – effectively and safely.

The Port Expansion Solution sets new industry standards with cutting-edge modelling software. It allows you to radically reduce your dredging costs and environmental impact for channel expansion and ongoing maintenance.

You'll get an integrated solution for port expansion projects from beginning to end.


Many ports spend millions of dollars more than is necessary when adapting to larger ships. Why? Because the use of conventional methods often results in overly conservative estimates. This significantly raises expansion CAPEX and OPEX costs – potentially intensifying environmental impacts.

Imagine using the most accurate solution in the market to optimise your channel operability and sustainably grow trade now and into the future:

Significant savings in dredging costs

We have saved USD 10-100 million for previous clients, or up to 20-50% compared to conventional methods.

Reduction in environmental impact

By reducing dredge volume requirements and incorporating dynamic frameworks for regulating and optimising dredging operations.

7-day forecasts

Detailed forecasting of environmental conditions with a web interface, allowing for dynamic scheduling and viewing by port operators.

Improved risk management

Due to a transparent and highly accurate methodology for assessing operational safety through navigational channels and at berth.

“The Channel Capacity study by DHI has provided us with a thorough understanding of the capacity and operational capability of our 90 km long channel. Using the latest advances in numerical modelling of dynamic response of powered vessels subject to waves, tides, winds and currents, the operational system developed by DHI allows for the forecast and management of the under keel clearances (UKC) of large commercial vessels accessing the Port of Brisbane.”

“DHI’s integrated channel capacity modelling methodology provided the highly accurate and robust analysis demanded by the Port of Geelong to provide the confidence required to bring in large Suezmax tankers without extensive channel widening and dredging. The channel capacity analysis undertaken by DHI has saved significant capital works dredging costs for the Port and assisted to improve the economics of a major client of the Port.”

How it works

Significant reductions in dredging costs and successful port operability require a highly accurate and comprehensive software.

The Port Expansion Solution delivers:

An integrated approach

Integrated numerical models allow you to investigate the accumulated effect of multiple constraints, for substantial cost and time savings and reduction in environmental impacts.

Hydrodynamic and wave modelling

Incorporating long-term dynamic variations in wind, water level, currents and waves to ensure realistic representation of environmental conditions and impacts throughout the port domain.

Channel capacity and under keel clearance

The most accurate assessment of powered vessel response with the same level of sophistication as high-end full-bridge vessel simulators.

Moored vessel analysis

Simulation of moored vessel motion in ports and harbours exposed to multi-directional sea states or passing vessels enables you to support effective mitigation strategies.

User-friendly web interface

Improved understanding of port operability and effective utilisation of operational forecast services using modern web services.
