Our dredging studies consider all aspects of the required works, ranging from the ground conditions and the prevailing weather and ocean conditions to selecting a suitable plant to assess the optimal approach for completing each project.

We have experience in a wide range of dredging methods, dredging related issues and complimentary services.

Our services include:

  • Reclamation advisory and design
  • Dredging options assessment
  • Dredged material characterisation
  • Sand bypassing and beach renourishment projects
  • Unexploded and exploded ordnance (UXO/EXO) investigations
  • Port planning to define dredging needs
  • services, including peer review.
  • 3D Dredging Model of Walker Shoal


  • Review and assessment of relevant site data to determine project requirements and constraints
  • Identification of likely project constraints
  • Evaluation of geotechnical/ geophysical data to assess the ability to dredge
  • Evaluation of dredged material disposal options, including offshore disposal and reclamation
  • Selection of appropriate dredging equipment
  • Assessment of site conditions and associated implications for the effectiveness of dredging equipment
  • Determination of proper project execution methodology
  • Evaluation of ‘constructability’ requirements and the optimized staging of works
  • Preparation of detailed ‘internal’ cost estimates based on in-house experience and guidelines
  • Management of contractor requests for cost estimates
  • Validation and review of dredge production rates and workability limits

Metocean studies

Our understanding of the metocean processes and conditions that influence the design and operation of marine infrastructure is based on extensive experience in the industry.

We use in-house historical metocean databases, numerical modelling, and analysis to inform the criteria for operations, preliminary design, front end engineering design, mooring layout design and breakwater and terminal design, including coastal erosion modelling and coastline evolution under the influence of shoreline recession and sea-level rise.

Keeping the channels open

Our experience in managing the whole life cycle of dredging projects mean that we are best placed to assist our clients in ensuring timely execution and best value for money from the engineering design, procurement, execution and maintenance phase.

Silting assessments

Silting at terminals requires regular dredging to maintain navigation channels.

Reclamation and sand bypassing

We provide an integrated approach to managing capital and maintenance dredging, reclamation, and sand bypassing.
