The first dredger built by Damen Shipyards Group for Australia, the 60-meter Tommy Norton, has now started work to deliver safe and reliable ocean access for the commercial vessels, oil & gas suppliers and commercial fishing fleet that cross the entrance bar to the Gippsland Lakes area. Propulsion is provided by two SCHOTTEL Rudderpropellers type SRP 330 fixed pitch.

Capable of dredging to depths of 15 meters, the dredger has been built with bottom doors to enable self-emptying and can alternate between a bow connection and rainbow expulsion for beach reclamation work. In order to increase the vessel’s payload capacity when dredging sand with a high specific density, Damen has reduced the freeboard of the vessel and applied a dredge mark.


The SCHOTTEL Group, with its headquarters in Spay/Rhine, is one of the world’s leading manufacturers of propulsion and steering systems for ships and offshore applications. Founded in 1921, the company has been developing and manufacturing azimuth propulsion and manoeuvring systems, complete propulsion systems with power ratings of up to 30 MW, and steering systems for vessels of all sizes and types, for about 65 years. Around 100 sales and service locations worldwide ensure customer proximity. For more information, please visit
