Bunbury and Port Hedland Maintenance Dredging

We were engaged by the Bunbury Port Authority in 2004 and again in 2007 to manage maintenance dredging works undertaken in the harbour and channel areas of the Port.


The Port of Port Hedland is one of Australia’s largest bulk export terminals, the primary commodity being iron ore.

Similarly, the Port of Bunbury is a large mainly bulk commodity port. Maintenance dredging is required approximately every 3 years to keep the inner harbours and their access channels cleared to design depth.

Dredging contracts involve the removal of up to 750,000 m3 of soft sediments by trailer suction hopper dredge (TSHD) at each location.

In 2004, both contracts were awarded to Dredeco Pty Ltd, who deployed one of the largest TSHDs in the world at the time - the 24,000 m³ hopper capacity, Pearl River.

We provided dredge supervisors on board the dredge 24 hours a day.

We were awarded separate contracts by the Port Authorities of Port Hedland and Bunbury to provide project management services for maintenance dredging campaigns in 2004 and 2007, respectively.

Synergies were created through the management of both projects which resulted in savings for both customers.
