Rosslyn Bay

Rosslyn Bay is situated just east of Rockhampton, adjacent to Yeppoon, in Northern Queensland. The central feature of the town is its busy harbour, used by both commercial and recreational vessels. The harbour is within Keppel Bay and close to the Mackay/Capricorn management area of the Great Barrier Reef Marine Park.

The harbour requires maintenance dredging about every 3-4 years to maintain accessibility and internal public channels.

Birdon was awarded a maintenance dredging contract to improve navigational access to the Boat Harbour in 2012 and again in 2016.

In excess of 85,000m3 of material was dredged in 2012 followed by another 75,000m3 in 2016. The material consisted of a combination of silt and sand. Dredged materials were transported via a submerged underwater pipeline to an offshore disposal area approximately 1.1km from the Harbour entrance.

The work was carried out using Birdon’s cutter suction dredge “DARWIN” on both occasions.
