Our Projects 

Port of Melbourne

​Yarra River Services Protection Dredging Project, Australia.

Tendering Support

i2D evaluated the feasibility of using Water Injection Dredging as an alternative methodology for dredging sediments from service protection structures.

The scope of this evaluation included reviewing tender packages and assessing contractors’ work methodologies and contract types.  It also involved conducting a project risk assessment and estimating production rates.

BUSS Terminal Eemshaven B.V.

Julianahaven Soil Improvement Project, The Netherlands

Project Management

After conducting a spud can punch-through analysis and managing the soil investigation campaign, i2D assisted BUSS with the project’s execution.  This involved managing the dredging contractor responsible for the soil improvement works identified as necessary by the punch-through analysis.

Additionally, i2D monitored quay side stability during the dredging works.

Roy Hill Holdings

Port Hedland Stanley Point Berth 3 Expansion, Australia.

Dredging Works Tendering Support

i2D was engaged to provide technical support to the Roy Hill technical and procurement project team for the tender package’s preparation.  Our role included assisting the team in evaluating tender responses.

Furthermore, we reviewed proposed work methods, conducted shadow estimates and provided technical evaluations for each submitted response.

Energy Resources of Australia

Dredging Tailings at the Ranger Mine, Australia

Management of Dredging Operations

i2D was tasked with managing the contractor to ensure the project’s two dredgers were maintained and operated safely and efficiently.

We also monitored the contractor’s performance daily using i2D’s Equipment Performance Review tool to boost productivity.

In addition, the i2D team mobilised and commissioned a new dredger and supervised its operation

Copenhagen Offshore Partners

Offshore Windfarm Subsea Cable Burial, Taiwan.

Dredging Consultancy Services

i2D prepared production estimates for the cable burial works using Trailing Suction Hopper Dredgers and Mass Flow Excavators.

Moreover, we conducted analyses for an unforeseen soil condition claim.

Hai Long Offshore Wind Power Co. Ltd

Hai Long Offshore Wind Project, Taiwan.

Dredging Consultancy Services

For this project, i2D carried out suitability inspections of the proposed Trailer Suction Hopper Dredger.  We also conducted a risk and opportunity assessment for the cable trench dredging works.

Furthermore, i2D developed the trench seabed preparation’s requirements and program, and recorded and monitored execution of the works.

Additionally, i2D provided shadow estimates along with scope of works and technical specifications for the dredging activities.

McConnell Dowell Constructors

Osborne Naval Shipyard Maintenance Dredging, Australia.

Specifications Support Services

i2D supplied specifications for further geotechnical investigations required for the maintenance dredging operations at the Osborne Naval Shipyard.

In addition, we provided productivity estimates, conducted Return Water Modelling and reviewed the contractor’s maintenance dredging methodology.

Daewoo E&C Co. Ltd

Al Faw Grand Port Development Project, Iran.

Maintenance Dredging Support Services

For this project, i2D was tasked with conducting hydrodynamic modelling for Placement Turbidity and Return Water Quality.  We also conducted a Threshold of Motion study for soil hydraulically placed in the offshore dumping area.

Furthermore, i2D performed a feasibility assessment for offshore dumping in a shallow area and developed maintenance dredging manuals for the navigation channel and the port basin during the operational phase

Australian Naval Infrastructure

Henderson Large Vessel Dry Berth Project, Australia.

Conceptual Design Review

i2D assisted Australian Naval Infrastructure in selecting dredger types and work methodologies and we identified the implications of the various options.

Moreover, we specified all necessary additional field investigations, detailed onshore and underwater disposal options and identified potential environmental restrictions.  We also estimated project volumes, productivity, cost and duration.

Queensland Ports Association Inc

Long-Term Maintenance Dredging Programme, Australia.

Maintenance Dredging Programme Management and Tender Support

in2Dredging (i2D) provided strategic support to the Queensland Ports Association Inc (QPA) in developing and implementing a Long-Term Maintenance Dredging (LTMD) Programme. The engagement began with defining and scoping the programme to establish a consistent framework across all QPA-represented ports.

i2D then conducted a detailed assessment of service delivery options, analysing dredging requirements alongside each port’s operational, environmental, and regulatory context.

Drawing on these insights, i2D developed a programme plan that informed the technical specifications for the LTMD tender process. These specifications ensured clarity, consistency, and alignment with strategic and regulatory objectives, thereby enabling a transparent and effective procurement process for ongoing maintenance dredging.
